Transport’s journey to sustainability

Over the past year, our ability to travel within the UK and further afield has been heavily restricted as a result of the ongoing Covid-19 pandemic. As a result of ongoing restrictions, there has been a reduction in the amount of carbon dioxide emitted by the UK. According to figures published by the Department for Business, Energy, and Industrial Strategy (BEIS), over the past year, the UK has recorded a 10% reduction in carbon emissions. The reason for this large fall has been attributed to the substantial drop in road traffic as a result of several national lockdowns.

Analysis by BEIS found that in 2020 there was a 19.6% reduction in the amount of carbon dioxide emitted by the transport sector. Previous research found that the transport sector was the biggest polluting sector in the UK, therefore, the reduction of the number of cars on our roads naturally had a considerable impact on our overall carbon emissions.

As this year’s host of the UN COP26 climate conference, and signatories of the Paris Agreement, the UK is committed to and has a large role to play in the journey to reach carbon neutrality by 2050. Therefore, as we see restrictions ease, the way we use transport cannot simply return to business as usual.

Sustainable choices

Naturally, as we return to something closer to normality, people’s need to travel and move around will increase. Whether it’s returning to the office or going on holiday, transport levels will be quick to return to normal levels, with statistics published by Transport Scotland highlighting that in the past week car journeys were only down 10% compared with the pre-pandemic baseline.

It’s unrealistic to ask people to reduce their transport to the levels seen during national lockdowns. However, we all can make more sustainable choices when it comes to our everyday journeys.

There are several options available when it comes to making sustainable choices around our method of transport. All of these options tend to focus on reducing our dependency on petrol/diesel cars, particularly, when it comes to short journeys which can be made using active or public transport.

Research conducted by the University of Oxford’s Transport Studies Unit found that switching from the car to active transport for one day a week could result in an individual’s carbon footprint being reduced by a quarter. Additionally, regularly walking or cycling has been found to improve our physical health, reduce anxiety, and improve levels of self-esteem. However, our ability to switch to alternative means of transport is heavily reliant on the provision of sustainable transport infrastructure.

Supporting sustainable infrastructure

For people to make more sustainable choices surrounding their method of transportation, infrastructure that supports active and public transport will have to be as reliable and safe as using a car. Across the UK, there is often a disparity in the choices that are available to people, this is particularly acute for people who live in less densely populated areas.

Expanding and improving active transport infrastructure is a relatively cost-effective way in which local authorities and governments can reduce the carbon emitted by the transport sector.

On top of the previously mentioned personal health benefits, research commissioned by the European Commission has found that there are many economic benefits to the deployment of sustainable transport infrastructure. There was found to be strong evidence that the following interventions had both environmental and economic benefits:

  • enhancements to public transport systems
  • cycling infrastructure
  • personalised travel plans (PTP)

The development of PTPs has been flagged as a particularly cost-effective way to help people  make more sustainable transport choices. Evidence from across the world has found PTPs are successful in reducing the number of car journeys made. Information about the state of a local transport network (for example, how many rental bikes are at a station or when the next bus will arrive), can help individuals make more sustainable choices. 

Smarter transport

For PTP to be successful, the transport network has to get smarter and provide real-time information about the state of the network. This includes information on the availability of rental bikes, the time of the next arriving bus, and if there are points of congestion that should be avoided. All of this can be used to enable individuals to make more sustainable choices that are responsive to changes in the transport network.

At Idox, we are at the forefront of designing solutions that can support the deployment of smarter transport networks. From urban traffic management and control to real-time passenger information, these interventions can help support the development of sustainable transport networks and allow individuals to make better choices.

Final thoughts

We’ve all had to make changes to our day-to-day lives over the past year to protect our communities from Covid-19. The threat posed by climate change poses a similar threat to our day-to-day lives. If we are to reach carbon neutrality, we all have to make changes to reduce our carbon footprint.

Making more sustainable transport choices is a simple action that we can all take to reduce the carbon emitted by the UK’s most polluting sector. By making these choices we won’t only be protecting our environment and local communities, we will also be improving both our physical and mental health.

However, to make these choices, the development of smart sustainable transport infrastructure will need to be a focus. Here at Idox, we stand ready to help and have solutions that can make the transport sector smarter and more sustainable.

Idox’s transport solutions support traffic management and the delivery of real-time passenger information across all modes of transport. Innovative services and solutions enable complete management across all forms of transport, supporting the safe and efficient movement of people and vehicles – whatever the end goal.

Close to home: getting to net zero means decarbonising the UK’s housing stock

Photo by Erik Mclean on Unsplash

Two years ago, the UK became the first major economy in the world to pass a law pledging to bring all greenhouse gas emissions to net zero by 2050. Achieving net zero means balancing the amount of greenhouse gases we emit with the amount we remove, and it’s a critical factor in tackling climate change by reducing global warming.

But, according to the government’s independent adviser on tackling climate change, the UK will be unable to meet the net zero target without the near-complete elimination of greenhouse gas emissions from 29 million homes. 

The necessity: why buildings need to be decarbonised

In 2014, emissions from domestic properties accounted for 34% of total UK greenhouse gas emissions. A combination of high energy prices and improvements in energy efficiency brought that figure closer to 19%. But those reductions have stalled, and because the UK’s building stock is one of the oldest and most energy-inefficient in Europe, the need to decarbonise is even more urgent.

The benefits: environmental, health, economic

While achieving net zero is one good reason for making our buildings more energy efficient, decarbonisation offers further dividends.

Energy efficient homes are cheaper to run, reducing the levels of fuel poverty that affect millions of households. They can also bring health benefits in the form of healthy air temperatures, lower humidity, better noise levels, and improved air quality.

In addition, a nationwide programme of decarbonising buildings could make a vital contribution to the recovery of the economy from the coronavirus pandemic. A recent inquiry by the House of Commons Environmental Audit Committee  (EAC) found that investing in energy efficiency alone could create 34,000 full-time jobs within the next two years. In the longer term, energy efficiency investment could support an estimated 150,000 skilled and semi-skilled jobs to 2030.

The problems: high costs, skills uncertainty and a “disastrous” insulation scheme

The UK government says the cost of decarbonising homes is between £35 billion and £65 billion. But the EAC believes that this seriously underestimates the cost of upgrading the energy efficiency of homes. With 19 million homes in England requiring energy efficiency installations, this could cost £18,000 per home, even before the installation of a heat pump.

Another area of concern is skills. Brian Berry from the Federation of Master Builders told the committee that every tradesperson in the country needs to be upskilled in retrofit techniques in order to secure overall competency in the supply chain:

“We need to upskill people in the building industry because there is a need to understand how their skills interrelate to one another. You cannot just pick out one bit of this. It has to be seen holistically, which is why I think there needs to be a national retrofit strategy, a clear political direction and a commitment to reducing carbon emissions in our homes.”

The EAC was also outspoken in its criticism of the government’s flagship home insulation scheme. The Green Homes Grant was launched in 2020 to offer £1.5bn in subsidies for insulation and low-CO2 heating. However, only 6.3% of the money has been spent, despite exceptionally high demand.

The committee said the scheme was rushed and poorly implemented, and described its administration as “nothing short of disastrous.” Just six months after its launch, the scheme has now been scrapped. Instead, energy saving upgrades and low carbon heating will be delivered to homes through local authorities in England.

The recommendations: strategies, incentives and insights from overseas

There’s no shortage of suggestions for driving decarbonisation forward. The EAC has called for a government strategy for the next decade to give industry and tradespeople time to upskill and to give households the right signals to invest in energy efficiency. The committee also recommends that VAT on the labour element of refurbishment and renovations is reduced to 5%, a measure also supported by the Royal Institute of Chartered Surveyors.

It’s also worth looking at ideas from overseas. In February, research by the University of Edinburgh reviewed the heat decarbonisations policies in nine European countries. The report highlights particular progress made by the Nordic countries in decarbonising buildings’ heat supply and in making greater use of electricity as a potential future source of low-carbon heating.

The solutions: putting promises into practice

While the challenge of decarbonising homes may be daunting, a growing number of housing providers are taking steps to cut emissions from domestic properties.

The Welsh Government has provided £20m in funding for Optimised Retrofit. Through this scheme, 28 social landlords can retrofit homes and test the ways heat and energy are produced, stored and supplied. If it’s successful, the scheme could be the model for decarbonising all of Wales’ 1.4 million homes by 2050.

Last month, Sutton Council launched an energy-efficiency programme to transform draughty properties with high energy bills into net zero carbon houses which are warmer and cheaper for residents. The programme is based on a successful Dutch initiative known as Energiesprong (energy leap). In the Netherlands, 1300 net zero energy refurbishments have been completed, and a further 500 are being built. The initiative involves insulating the external walls and roof areas, replacing windows and doors and installing new solar panels to power a new central heating and ventilation system. Sutton is the first London borough and the latest UK housing provider to adopt the programme, which has already been taken up in Nottingham and Maldon.

Many housing associations are at the start of their journey to net zero, but a National Housing Federation survey has shown that two thirds of social housing landlords have started planning to make their homes greener and warmer. Three quarters (74%) of survey respondents expect to retrofit homes in 2020-21. A similar proportion (73%) expect to retrofit homes in 2021-22. However, the survey also reported that lack of finance and continuing policy uncertainty remain major obstacles to decarbonising homes. That’s important, particularly given the cost of decarbonisation of social housing – £104bn by 2050.

The future: decarbonisation begins at home

Local authorities, housing associations, and the construction industry are all keen to transform existing homes into greener, warmer places to live in. At the same time, residents – especially those having to make the choice between heating or eating – need to be taken out of fuel poverty. And, as we’ve seen, achieving net zero will only be possible by making the nation’s housing stock more energy efficient.

With so much riding on decarbonisation of domestic properties, the need for more funding as part of an ambitious policy approach is clear. As the UK prepares to host the critical climate change talks in Glasgow this year, there has to be a better understanding that tackling the climate emergency starts on our own doorstep.

Creating carbon conscious places

Last week, we reported on a series of webinars organised by Partners in Planning, a partnership of key organisations and sectors to support Scotland’s planners in delivering successful places.

This week, we’re looking at a further webinar in this series, which focused on the creation of low carbon places.

Planning for carbon conscious places

Steve Malone and Heather Claridge from Architecture & Design Scotland  (A&DS) opened the webinar by describing how A&DS have been exploring how the challenge of climate change can act as a driver towards the creation of low carbon places.

A&DS has been supporting the Scottish Government in implementing its climate change plan at a local level. This recognises that the planning system plays a key role in tackling climate change, and helping Scotland achieve its carbon emission targets.

Over the course of a year, A&DS worked with four local authorities to develop and deliver plans that prioritised climate action. As a result, a number of key principles of a carbon conscious place were identified.

  • A place-led approach
  • A place of small distances
  • A place designed for and with local people
  • A place with whole and circular systems
  • A place that supports sharing (of assets and services)

These principles are closely connected with ideas identified in earlier work by A&DS which explored how placemaking can tackle the challenges of an ageing population.

A&DS further developed this work to imagine the changes that might need to happen to support more carbon and caring conscious places by 2050. Earlier this year, its report Designing for a Changing Climate shared the learning from the year-long exploration into a whole place approach to the net-zero carbon challenge.

The report provided examples of each of the principles in action, and considered what Scotland would look like in 2050 if these principles were adopted for urban neighbourhoods, city centres, towns and rural areas.

Among the ideas highlighted were:

  • rooftops repurposed as usable areas with green space and room for urban growing
  • accessible zero emission public transport connecting city centres
  • local food growing and agroforestry helping support food self-sufficiency and security
  • natural flood defence schemes
  • peatland and woodland restoration to help a rural area absorb carbon and balance emissions

A&DS is now working with local authorities to apply these principles in real places. For example, in Clackmannanshire, the principles are being used to guide development of a mixed use housing site in Alva.

Planning as a circular economy enabler

Later in the webinar, Angela Burke and Ailie Callan from the Scottish Environment Protection Agency (SEPA) considered how the design of places that are conducive to the circular economy can help to tackle climate change.

Since the industrial revolution, the world’s economies have used a linear “take-make-consume-dispose” pattern of growth, a model which assumes that resources are abundant, available and cheaply disposable.

In contrast, a circular economy changes that mindset by designing-out waste and pollution, keeping products and materials in use and regenerating natural systems. These principles not only apply to resources such as consumer goods and product packaging, but also to land, water, buildings, infrastructure and energy.

Angela and Ailie went on to describe how planning can be an enabler of the circular economy. In Scotland, the planning system is set to change, with the publication of a new National Planning Framework (NPF4), which sets out where development and infrastructure is needed to support sustainable and inclusive growth.

NPF4 will address a number of high level outcomes, such as meeting the housing and wellbeing needs of the people of Scotland and meeting targets for reducing greenhouse gas emissions. Integrating circular economy principles early in the planning process will help to deliver a number of these outcomes, and NPF4 policy will provide the framework to ensure that these principles are integrated into new developments.

Ailie provided some examples of how circular economy principles can be embedded into planning:

  • Brownfield sites can be redeveloped instead of developing new sites and generating higher carbon emissions.
  • Distribution nodes on key transport corridors can enable electric vehicles to carry out last stage of delivery, minimising emissions and reducing traffic.
  • Developing re-use hubs at these distribution nodes can drive down waste.
  • Mobility hubs can ensure that everyone is well connected, not just for public transport, but also cycle paths, routes for mobility vehicles and charging points for electric vehicles.
  • Planning for shops and services locally (perhaps sharing the same premises) will reduce the need to travel outside the local area.

Angela and Ailie concluded with an invitation to anyone interested in partnering with SEPA on developing the circular economy in Scotland.

20 minute neighbourhoods

In the final section of the webinar, the Scottish Government’s Chief Architect, Ian Gilzean looked at 20 minute neighbourhoods. This is not a new concept, but has gained added significance due to the COVID-19 pandemic.

20 minute neighbourhoods are all about living more locally by ensuring people have most of their daily needs met within a 20 minute walk from home. This in turn improves quality of life and reduces carbon emissions.

20 minute neighbourhoods bring together a range of characteristics, including transport, housing, schools, recreation, shopping and local employment. Recent limitations on travel due to the coronavirus have given many of us a lived experience of 20 minute neighbourhoods. But they have also brought into sharp focus the barriers preventing people from accessing work, shops and services close to where they live.

Ian went on to describe the implementation of the 20 minute neighbourhoods concept in Melbourne, Australia. Since 2017 Plan Melbourne has embraced this concept, feeding into the ambition of Melbourne to become a more liveable, connected, sustainable city. While some parts of Melbourne, such as the inner suburb of Fitzroy, already enjoy the facilities that make up a 20 minute neighbourhood, some of the outlying suburbs do not, and Plan Melbourne has been aiming to tackle some of the problems that prevent these places from delivering on the concept.

20 minute neighbourhoods appear to be an idea whose time has come. The pandemic has triggered a rise in remote working, and especially working from home. At the same time, cities have seen significant rises in cycling numbers. The economic impact of COVID-19 is still playing out, but it’s already clear that the recovery of small businesses and local services will be a priority, along with the need to reimagine urban centres.

Ian explained that these factors have all fed into the Scottish Government’s Programme for Government, which has a strong focus on localism. This in turn has generated commitments and policies on town centre and community regeneration, local working hubs and active travel infrastructure, all underpinned by the new National Planning Framework.

Ian concluded with an example of a project in the Wester Hailes district of Edinburgh, where the city council has been developing a local place plan. The plan is making the most of existing assets, such as local canal and rail connections, as well as identifying new opportunities, such as cycle routes, food growing and green spaces.

Final thoughts

This webinar, along with others in the series, provided plenty of useful information about how Scotland is trying address climate change through the planning system, while also taking account of local communities’ needs.

Much more remains to be done if Scotland is to meet its net-zero ambitions, but it’s clear from the initiatives highlighted in these webinars that communities in partnership with local and national government and other stakeholders are working hard to create carbon conscious places.

How the planning system can help address climate change

The Scottish Government’s Climate Change Plan Update is due to be published this month (December 2020), after being postponed from April due to the coronavirus (COVID-19) pandemic.  The plan will provide an update on the Scottish Government’s Climate Change Plan, reflecting the new targets set out in the Climate Change (Emissions Reduction Targets) (Scotland) Act 2019, with the overall aim of reducing Scotland’s emissions of all greenhouse gases to net-zero by 2045. 

In the face of the climate emergency, the target is both admirable and ambitious.  Achieving it will require input from all sectors of the economy and society – from energy, transport, infrastructure to skills, training and innovation. 

A recent series of webinars held by Partners in Planning looked at the ways in which town planning could help play its part by embedding nature-based solutions and green infrastructure planning into the planning process.

In this blog we look at three innovative projects that were highlighted.  They illustrate some of the varied ways in which planning can contribute towards the Scottish Government’s net zero targets and address the wider climate emergency.

Building with Nature: green infrastructure benchmark

Encouraging developers to incorporate green infrastructure and nature-based solutions into new developments is a key challenge, particularly if there is a perception that it may be more time consuming and/or costly to do so.

Building with Nature is a set of wellbeing standards built around the ‘3 Ws’ – water, wildlife and wellbeing.  The standards go beyond statutory requirements, bringing together evidence, guidance and good practice to provide something akin to a ‘how to’ guide for creating places that benefit both people and nature.  The standards are free to access and use, and there is also a paid-for accreditation scheme, with three levels of achievement – design, good, and excellent.

As well as reducing carbon emissions, the standards aim to help support biodiversity, promote flood resilience and support wellbeing through the provision of green space that is both inclusive and accessible to everyone, regardless of age or disability.

The standards are entirely voluntary but many local authorities are now beginning to either refer developers to Building with Nature or incorporate them as requirements in their own plans.

Plans themselves can also become accredited.  Indeed, West Dunbartonshire Council’s Local Development Plan 2, published in August 2020, is the first Building with Nature accredited policy document, achieving the ‘excellent’ rating.

Building with Nature have also recently launched a new national award scheme, with the first winners being Forth Valley Royal Hospital and Larbert Woods.

Green-blue roofs – Meadowbank, Edinburgh

One way that developers can incorporate nature-based solutions into their developments is through the use of green-blue roofs. Green-blue roofs can provide a range of benefits for both people and nature – including surface water management, urban cooling, as well as providing habitats for wildlife and opportunities for people to access nature in the urban environment.  

At present, there is no mandatory policy for green roof infrastructure in Scotland, thus while developers may be aware of the benefits that they have, many do not incorporate them into their plans due concerns about their impact on scheme costs and viability.

These concerns have been addressed in a study of the viability of incorporating green-blue roofs into a mixed-used development at the former Meadowbank Stadium site in Edinburgh, conducted by Collective Architecture on behalf of NatureScot (previously called Scottish Natural Heritage). 

The study highlights the varied range of green-blue roof options available to developers – all with different costs, levels of maintenance, building requirements etc.  Some are suitable for public access whereas others are not.  Blue-green roofs are a combination of both green roofs and blue roofs – where rainwater is retained rather than drained (as with a typical green roof) and released in a controlled manner.

Overall, green-blue roofs were found to be a viable option for the Meadowbank development, freeing up space that might otherwise be used for ground-based SUDS (sustainable drainage systems), and offering a range of potential wellbeing and community benefits.  Blue-green roofs did cause a small uplift in roofing costs. However, as a proportion of the overall construction costs, these were minimal, coming in at around £350 per dwelling.

Retrofitting green infrastructure – Queensland Gardens, Cardonald, Glasgow

If our towns and cities are to become truly carbon neutral, then there will also be a need to retrofit green infrastructure into existing developments.  One such example of retrofitting is Queensland Court and Gardens – a partnership between Southside Housing Association and Glasgow City Council to retrofit green infrastructure designs into two multi-storey tower blocks and the surrounding land in Cardonald, Glasgow. 

The project is part of the wider Green Infrastructure Strategic Intervention (GISI) programme, which as well as contributing to the ultimate goal of achieving a net zero carbon society, seeks to demonstrate how green infrastructure can be used to address some of the key issues faced in urban areas – from declining economic growth, social inequalities, pollution, flooding, noise, multiple deprivation, health problems and limited biodiversity. 

One of the key issues facing the outdoor space at Queensland Gardens is excess surface water, which renders much of the space unusable.  As such, the project has also received funding from 10,000 Raingardens for Scotland.  It plans to turn the rainwater run-off from the tower blocks into a feature that is incorporated into the gardens.  It also plans to expand the current parking facilities, create a shared community green space, and enhance the currently very limited play space for children and young people.

Both the Queensland Gardens and the Meadowbank site developments will be assessed against the Building with Nature standards.

Green infrastructure as part of the green recovery

The coronavirus pandemic has brought into sharp focus the importance of having local green spaces that are both easily accessible and inclusive of all ages and disabilities.  It highlighted the importance of nature to the health of society and the world more broadly, along with the urgent need to address climate change.

It also demonstrated that it is possible to create and implement innovative solutions to global crises on a tight timescale, when both the need and will exist.  There are strong calls now for a ‘green recovery’, and it is expected that the imminent Climate Change Plan Update will feature this concept heavily.  Indeed Scotland has already made a number of commitments for a green recovery as part of their 2020/21 Programme for Government, and the findings of the recent Green Recovery Inquiry reinforce its importance.

As the above examples show, embedding green infrastructure and nature-based solutions into the planning system is one way to help achieve Scotland’s goal of becoming net zero by 2045.  By doing so, we can create places and spaces that benefit not only ourselves, but also society and the planet.

‘Bending the Curve’ of biodiversity loss – could Covid-19 be the catalyst for change?

dead forest pic

“The evidence is unequivocal – nature is being changed and destroyed by us at a rate unprecedented in history” (WWF)

The latest Living Planet report from the Worldwide Fund for Nature (WWF) finds that 68% of the world’s wildlife populations have been lost since 1970 – more than two thirds in less than 50 years – with the most striking result a 94% decline in tropical subregions of the Americas. The report says this ‘catastrophic’ decline shows no signs of slowing. The cause – human activity.

Until 1970, the ecological footprint of the human population was less than the rate of the Earth’s regeneration. Explosive growth in global trade, consumption, population growth and urbanisation means we are now using more of the world’s resources than can be replenished:

“To feed and fuel our 21st century lifestyles, we are overusing the Earth’s biocapacity by at least 56%.” (WWF)

The environmental impact of human activity is hardly a new topic but the numerous warnings over the years haven’t had the desired effect of changing society’s trajectory. The stark warnings from recent reports including the 2018 IPCC (Intergovernmental Panel on Climate Change) special report on the impacts of global warming, and popular programmes such as the Blue Planet II series which highlighted the devastating impact of pollution on the world’s oceans, have certainly helped heighten awareness and action has been taken across the world to address the climate emergency. Unfortunately, the progress made so far is not enough to reverse the current declining trends.

But the new report raises hope in that times of crisis new ideas and opportunities for transformation can arise and that the current Coronavirus (COVID-19) pandemic could perhaps be the catalyst for such change.

‘People and nature are intertwined’

COVID-19 has undoubtedly injected a new sense of urgency, emphasising again the interconnectedness of humans and nature. It has provided a stark reminder how unparalleled biodiversity loss threatens the health of both people and the planet.

Factors believed to lead to the emergence of pandemics – including global travel, urbanisation, changes in land use and greater exploitation of the natural environment – are also some of the drivers behind the decline in wildlife.

The report emphasises that biodiversity loss is not just an environmental issue, but also a development, economic, global security, ethical and moral one. And it is also about self-preservation as “biodiversity plays a critical role in providing food, fibre, water, energy, medicines and other genetic materials; and is key to the regulation of our climate, water quality, pollution, pollination services, flood control and storm surges.”

As well the pandemic, a series of recent catastrophic events are used to underline the intrinsic links between human health and environmental health, including: Africa’s plague of locusts in 2019 which threatened food supplies, caused by the unusually high number of cyclones; extreme droughts in India and Pakistan in 2019, leading to an unknown death toll; and Australia’s most intense bushfire season ever recorded, made worse by unusually low rainfall and record high temperatures, as well as excessive logging.

Alongside this, the “extraordinary gains in human health and wellbeing” over the past century, including reduced child mortality and increased life expectancy, are highlighted as a cause for celebration but the study warns that the exploitation and alteration of the natural environment that has occurred in tandem threatens to undo these successes.

Biggest threats to biodiversity

Clearly, biodiversity is fundamental to human life and it is vital that the drivers of its destruction are addressed; and quickly.

Drawing on the Living Planet Index (LPI), which tracks the abundance of mammals, birds, fish, reptiles, and amphibians across the globe, using data from over 4,000 different species, the report identifies the major threat categories to biodiversity:

  • Changes in land and sea use
  • Invasive species and disease
  • Species overexploitation
  • Pollution
  • Climate change

It may be surprising to learn that climate change has not yet been the main driver of biodiversity loss. In fact, globally, climate change features lower on the scale of threats than the other drivers in almost all regions. Changes in land and sea use is the biggest proportional threat, averaged across all regions, at 50%. This is followed by species exploitation at 24% with invasive species taking third place at 13%. Climate change accounts for 6% on average.

However, the report warns projections suggest the tables are set to turn with climate change overtaking all other drivers in the coming years.

But all is not lost yet. The report argues that it is possible to reverse these trends and calls for action to do so by 2030.

Bending the Curve’

This year’s report highlights findings from significant new research, the Bending the Curve initiative, which uses pioneering modelling of different human behaviour scenarios aimed at restoring biodiversity. It argues that this has provided ‘proof of concept’ for the first time that we can halt, and reverse, the loss of nature while feeding a growing population:

“Bending the curve of biodiversity loss is technologically and economically possible, but it will require truly transformational change in the way we produce and consume food and in how we sustainably manage and conserve nature.”

2020 has certainly made the whole world stop and think. And it has provided an opportunity to reset humanity’s relationship with nature. Encouragingly, there has been widespread talk of a ‘green recovery’ from the pandemic and the British public have recently backed a “fairer, greener Britain” amid concerns the government might be rushing the country back to a ‘business-as-usual’ model.

Achieving a balance with nature will clearly require systemic change, as the Living Planet report shows. In the words of Sir David Attenborough, above all it will require a change in perspective”.

Role models for a new economic landscape: lessons from Europe’s Green Capitals

Hamburg: StadtRÄDER bike rental system

Last month, the French city of Grenoble was crowned European Green Capital for 2022. Since 2010, this award has been presented by the European Commission to cities judged to be at the forefront of sustainable urban living.

Being named Europe’s Green Capital is good PR for any winning city, and the €350,000 prize is an additional incentive to win. But the award also places demands on the winners to build on the environmental improvements that helped put them in first place.

The key message of the award is that Europeans have a right to live in healthy urban areas. Cities should therefore strive to improve the quality of life of their citizens and reduce their impact on the global environment.

Cities bidding for the award are judged on a range of environmental criteria, including climate change, local transport, public green areas, air quality, noise, waste, water consumption, wastewater, sustainable land use, biodiversity and environmental management.

The award enables cities to inspire each other and to share examples of good practice. So far, 13 cities have been named European Green Capitals:

2010: Stockholm (Sweden)

2011: Hamburg (Germany)

2012: Vitoria-Gasteiz (Spain)

2013: Nantes (France)

2014: Copenhagen (Denmark)

2015: Bristol (United Kingdom)

2016: Ljubljana (Slovenia)

2017: Essen (Germany)

2018: Nijmegen (Netherlands)

2019: Oslo (Norway)

2020: Lisbon (Portugal)

2021: Lahti (Finland)

2022: Grenoble (France)

Green approaches

Each city has adopted different approaches during its year as a green capital.

  • One very clear example of Stockholm’s commitment to sustainable development during its year as European Green Capital was the opening of a new tramway. The line opened in August 2010 and quickly achieved substantial environmental and economic impacts.

  • One of the campaigns during Hamburg’s year as green capital in 2011 aimed to make it easier for citizens to switch from cars to bikes and public transport. The Hamburg Transport Association distributed 2,735 free tickets to friends and acquaintances of season ticket holders, and many visitors made use of the free advisory and ‘get involved’ activities of Germany’s national bicycle club. During the year, Hamburg’s StadtRÄDER bike rental system was also promoted, resulting in an 8% increase in the number of users.

  • Even before it was named as a European Green Capital, Grenoble, had already made efforts to address noise pollution, promote cycling and reduce speed limits. It has also taken a proactive approach to maximising its limited green space by encouraging citizen-led planting initiatives. Grenoble reduced greenhouse gas emissions by 25% from 2005 to 2016 and is working towards a 50% reduction by 2030.

Britain’s green capital

The only UK city to be awarded the European Green Capital prize is Bristol, which held the title in 2015. The city hosted a number of art projects to raise awareness about sustainable development. Bristol also began a trial of ‘bio-buses’ powered by biomethane gas, using human waste from more than 30,000 households, an initiative that was developed further in 2020.

The selection of Bristol opened up a serious debate about  the true value of the award, with some regarding it as a distraction from Bristol’s serious environmental issues, such as traffic congestion, while others were critical of public funding for some European Green Capital projects as wasteful.

However, an important legacy from the year was the publication of the “Bristol Method”, a knowledge-transfer programme aimed at helping people in other cities understand and apply the lessons that Bristol learned in becoming a more sustainable city.

The Bristol Method is made up of a series of modules, each of which uses Bristol’s experience to present a ‘how to’ guide on a particular topic. Topics include:

  • how to use partnerships to drive change;
  • how to use grants to support grassroots change;
  • how to prepare a winning bid for the European Green Capital;
  • how to grow the green economy in a city;
  • how to get more people riding bikes and walking;
  • how to protect and enhance green spaces in a city.

Green shoots for a post-Covid recovery

Although the world is currently preoccupied by the coronavirus pandemic, that other serious planetary threat –  climate change – has not gone away. So it’s significant that many governments see this moment as an opportunity to build radical green policies into their packages for economic recovery.

Some of the practical ideas developed over the past decade by Europe’s Green Capitals are important in their own right, but may also be seen as key elements in rebuilding economies that have been devastated by restrictions to suppress the coronavirus.

The German city of Essen, for example, (European Green Capital in 2017) has developed one of Europe’s largest infrastructure projects, restoring 80 kilometres of waterways and creating a network of green spaces. The project was not only an important climate adaptation milestone, but has also created new jobs and business opportunities. Essen has shown that it’s possible for a city which previously relied on heavy industry to transform itself into a vibrant and sustainable space for humans, animals and plants.

Another project, in the Dutch city of Nijmegen, (Green Capital in 2018) is a social enterprise that collects, restores and re-sells second-hand goods. The venture prevents waste, as well as employing people who can put their repair and retail experience to good use. Similar projects across the Netherlands have collected 20,000 tonnes of goods a year, with 80% being re-used. They also provide jobs for disadvantaged and disabled people who have found it especially difficult to enter the labour market.

Europe’s Green Capitals have already become role models for green economies throughout Europe and beyond. Now they can demonstrate the economic as well as the environmental benefits of building back greener.

Counting down the hours: could a shorter working week raise productivity and improve our mental health?

In 1930, the influential British economist John Maynard Keynes predicted that within 100 years the working week would have shrunk to 15 hours. He believed that as living standards rose people would choose to have more leisure time as their material needs were satisfied.

For a time, it looked as if Keynes might be right. In the post-war period, average working hours continued falling, and analysis by the New Economics Foundation has suggested that if this trend had continued we would currently have an average working week of around 34 hours.

But in the 1980s, labour market deregulation, reduced collective bargaining, and slower growth in pay for low income workers put the brakes on working time reductions.

In the UK, 74% of the workforce work an average of 42.5 hours a week. That’s longer than in any EU country, apart from Greece and Austria.

The benefits of a shorter working week

In recent years, the twin challenges of climate change and automation of jobs, along with growing concerns about mental health and work/life balance, have prompted a rethink on working hours.

For some, a shorter working week means compressing forty working hours into four days instead of five.  Others argue that a truly progressive four-day week involves fewer hours at work, with no reduction in pay.

While many employers may recoil at the prospect of paying the same wage for fewer hours, a growing body of evidence presents some strong arguments in favour of this approach:

  • Studies of working hours reductions have demonstrated increases in productivity over four days to compensate for the loss of the fifth working day.
  • Employees with reduced hours spend less time on inefficient tasks, such as meetings.
  • Fewer hours can mean less stress, greater work-life balance and increased motivation.
  • A 2020 study by Autonomy found that a four day working week could potentially reduce energy consumption for the extra non-working day by 10% and emissions intensity by 15%.
  • A shorter working week could have positive effects on gender equality.
  • Maintenance costs can be reduced if all employees are out of the office for an additional day each week.

The four-day week in practice: lessons from New Zealand

In May, New Zealand’s prime minister, Jacinda Ardern encouraged employers to consider the four-day working week as one of the ways the country’s economy could be rebuilt following the Covid-19 pandemic. She suggested that reductions in working hours could boost productivity and domestic tourism and improve work/life balance.

In fact, one New Zealand firm has already demonstrated the positive effects of a shorter working week. In March 2018, financial services company Perpetual Guardian began a two-month trial in which its 240 staff worked four eight-hour days, but got paid for five. The experiment was monitored by academics at the University of Auckland and Auckland University of Technology.

The findings from the trial showed that supervisors were able to maintain performance levels, and most teams recorded a marginal increase. Meanwhile, employees reported improved job satisfaction and a better work/life balance. In addition, many employees expressed a sense of greater empowerment in their work because of the planning discussions that preceded the trial. The success of the trial has now resulted in the four-day week being adopted as company policy at Perpetual Guardian.

The cost of cutting hours

Another working hours trial, in Gothenburg, Sweden, involved nurses in a care home being offered the chance to work six-hour shifts instead of eight, on full pay. While the trial resulted in improvements in staff satisfaction, health and patient care, the city had to employ an extra 17 staff, costing £1.4m. Critics of the scheme said the need to pump additional taxpayers’ money into the trial proved that it was not economically sustainable.

Cost is a potential stumbling block to further working hours reductions. A 2019 report from the Centre for Policy Studies (CPS) estimated that the cost to the UK public sector of moving to a four-day week would be £45 billion if attempted immediately, or £17 billion assuming generous productivity gains from shorter hours. The authors argued that such costs would require spending cuts in public services or substantial tax rises.

However, the Autonomy think tank has put the net cost of a 32-hour week at no more than £5.4 billion. Autonomy has also pointed to improvements in job quality for millions of public sector staff, the creation of 500,000 new jobs and reductions in the sector’s carbon footprint as potential benefits of shorter hours.

Burnout or rethink?

In October 2020, the 4 Day Week Campaign, Autonomy and Compass published Burnout Britain, looking at the impact of longer working hours. The report noted that over the past three years the length of the working day has increased steadily, resulting in a 49% rise in mental distress reported by employees. Women are experiencing particular pressures, with 43% more likely to have increased their hours during the Covid-19 crisis.

The report warned that beyond the coronavirus pandemic, the UK faces another serious public health emergency:

“…as well as an impending recession and mass unemployment, we are heading into an unprecedented mental health crisis”

The existing evidence suggests there’s a strong case to be made for reductions in working hours. Apart from the potential productivity gains and improvements in the quality of life, there are savings to be made in the costs of treating mental ill health caused by overwork.

Even so, government and employers will require further proof of the tangible benefits of a shorter working week before committing to permanent changes.

Crisis often accelerates change, and the Covid-19 pandemic has injected new urgency into the debate. Remote working, restrictions in the workplace and the threat of mass unemployment have demonstrated the need to reconsider the old rules that only months ago seemed set in stone.

We are still a long way from Keynes’ vision of a 15-hour week. But 2020 has shown that shining a light on previously unthinkable alternatives to our current ways of working is not only possible, but essential.

Guest post: biodiversity: where the world is making progress – and where it’s not

Vlad61/Shutterstock  Tom Oliver, University of Reading

The future of biodiversity hangs in the balance. World leaders are gathering to review international targets and make new pledges for action to stem wildlife declines. Depending on whether you are a glass half-full or half-empty person, you’re likely to have different views on their progress so far.

More than 175 countries agreed to 20 targets under the banner of the Convention for Biological Diversity, which was signed in 1992. The most recent plan, published in 2010, was to halt the extinction of species and populations by 2020 to prevent the destruction of global ecosystems and to staunch the loss of genetic diversity – the variety within the DNA of species’ populations, which helps them adapt to a changing environment.

But the targets were missed. An optimist might say that’s because they were laudably ambitious, and we’re making good progress nonetheless. The protection of land particularly rich in biodiversity has increased from 29% to 44% in just a decade, which is a huge policy achievement. On the other hand, we failed to halt global biodiversity loss during a previous round of global targets ending in 2010 and, a decade later, we are still far behind where we need to be.

A recent UN report compiled detailed assessments of the world’s progress towards each of the 20 targets. It highlights some small victories, and where the greatest gulfs exist between present action and necessary ambition.

The good news

The international community has made progress on several goals. We have improved our global capacity to assess biodiversity trends, and funding for conservation roughly doubled over the previous decade to USD$78-91 billion annually.

There is now an international protocol governing the fair sharing of genetic resources discovered in nature, so they cannot be plundered by companies from rich countries. This gives countries added incentives to protect their biodiversity, which might lead to new medicines or technologies for use in food production.

Two of the biggest drivers of biodiversity loss are habitat destruction and invasive species. Through scientific research and monitoring programmes, scientists are now better at identifying the pathways by which invasive species colonise vulnerable habitats. Protected areas have expanded across the globe too. Achim Steiner, leader of the UN Development Programme, stated that the world is on track to achieve protection of 17% of land and 10% of marine areas identified under the programme by the end of 2020.

All this has had a tangible effect. Up to four times as many birds and mammals likely would have become extinct in the past three decades without such actions.

The bad news

So far, so good. But all these successes are partial and ambiguous. Yes, we have increased funding for biodiversity, but this is still swamped by more than £500 billion in environmentally harmful subsidies, such as aid for the fossil fuel industry. Although we have identified more of the ways in which invasive species spread, there has been limited progress in actually controlling them. Though a significant area of the world is now designated as “protected”, management within these areas is still often inadequate.

What’s more, for many of the other targets, things have actually got worse. The loss and fragmentation of the world’s forests continues, depriving biodiversity of habitat and exacerbating climate change. Deforestation rates are only one-third lower in 2020 compared to 2010, and may be accelerating again in some areas.

Essential ecosystem services – such as the provision of clean water, soil for farming and pollinating insects – continue to deteriorate, affecting women, indigenous communities, and the poor and vulnerable more than others. We are still unable to even track changes in the genetic diversity of wild species, meaning we cannot assess these hidden changes in biodiversity which are important for the long-term resilience of a species.

The fundamental problem is that we have failed to address the underlying drivers of biodiversity loss. Targets for reducing pollution, habitat loss and climate change all show negative progress. We have achieved several easy wins, but the tougher challenges remain. Overcoming these will mean stopping the activities that are at the root of biodiversity loss.

We need better regulation of harmful chemicals which pollute the environment. Of the over 100,000 chemicals used in Europe today, only a small fraction are thoroughly evaluated or regulated by authorities, despite many causing harm to health and the environment. We need strong trade policies that prevent the destruction of primary rainforest for products such as palm oil and soy. Perhaps most of all, we need radical action on climate change, which is expected to overtake other drivers to be the number one cause of biodiversity loss in coming years.

These systemic changes require action from states and industries. But we can also take action as citizens and consumers. We need fundamental changes in the way we live – how we invest our money, the food we eat and how we travel. Each of us, making internet orders at the click of a button, has hidden power to influence the state of the planet. What we choose to buy, or not to buy, can help decide whether wild species flourish across the globe.

If world leaders fail to regulate unsustainable markets, then we need to be even more savvy about potentially harmful connections to the natural world that lie behind our purchases. Perhaps then we can start to be both optimistic and realistic about the state of our planet’s biodiversity.The Conversation

Build back better: is now the time for Green New Deals? – Part 2

A window of opportunity

In policymaking, there is a concept known as the “Overton Window”, which describes the range of policies that politicians can propose without being considered too extreme by the population at large. This window of opportunity can be shifted and can allow for policies that in the past may have been considered unthinkable and radical to become mainstream and even sensible.

The impact of Covid-19 and the public health measures that have been required to suppress the virus, have undoubtedly resulted in a shift in the “Overton Window”. Policy interventions, such as the Job Retention Scheme and national lockdown, which involved massive amounts of government spending and restrictions to every aspect of our day-to-day lives, suddenly became normal and were largely approved of by the public.

In these circumstances, the concept of the Green New Deal, a policy package which involves large amounts of government spending, designed to create green jobs, develop green infrastructure and modernise the economy, may no longer be such an unfeasible idea.

Build back better: a green recovery

The economic impact of Covid-19 is expected to result in a 5.2% contraction of global GDP, amounting to the deepest global depression since 1945. In order to recover from this contraction, governments are formulating unprecedentedly large economic stimulus packages, designed to mitigate the economic and social damage created by the pandemic. Already there are numerous examples of governments utilising aspects of the Green New Deal within their economic recovery plans.

European Union

Next Generation EU – A European Green Deal

Prior to the Coronavirus pandemic, the European Commission was already working on creating a European Green Deal, which would support the EU transition to climate neutrality by 2050. After the onset of the pandemic, the European Commission moved to position the Green Deal as a key pillar of the EU’s €750 billion recovery package, known as Next Generation EU. 25% of the recovery package has been dedicated to funding climate action, whilst the entire package features a commitment that any money spent as part of the EU’s economic recovery must “do no harm” to the EU’s climate neutrality goal. The recovery package includes policies that are similar in nature to other Green Deals, including:

  • a €40 billion ‘Just Transition Fund’, to alleviate the socio-economic impacts of the green transition and diversify economic activity;
  • a €91 billion a year fund to improve home energy efficiency and develop low carbon heating;
  • the introduction of an EU-wide border tax on carbon-intensive industrial imports with the potential to raise €14 billion.

French Government

France Relaunch

The French government’s recently announced €100 billion stimulus package, includes a €30 billion package of measures designed to aid France’s transition to carbon neutrality. The measures set out within the package incorporate core elements from Green New Deals, such as developing cleaner forms of transport and improving the energy efficiency of buildings. The package includes the following green measures:

  • a €11 billion investment in developing and encouraging the use of green transport methods, nearly €5 billion of which will be used to upgrade rail lines to encourage freight traffic from road to rail;
  • a €6 billion investment to help improve the energy efficiency of homes and other buildings;
  • A €2 billion investment to help develop the hydrogen sector.

Scottish Government

Protecting Scotland, Renewing Scotland

Within this year’s Scottish Government Programme, it is evident from the first page that it views the need for economic recovery as an opportunity to create a  “fairer, greener and wealthier country”. The programme explicitly describes the measures contained as “the next tranche of our Green New Deal” and borrows extensively from existing Green New Deals, with policies including:

  • a £100 million green Job Creation Fund;
  • a £1.6 billion investment to decarbonise the heating of homes and other buildings;
  • a £62 million Energy Transition Fund to support businesses in the oil, gas and energy sectors over the next five years to grow and diversify;
  • capitalisation of the Scottish National Investment Bank with £2 billion over ten years, with a primary mission to support the transition to net zero emissions.

UK Government

A Plan for Jobs

A key element of the UK Government’s plans to support and develop the labour market is the creation of green jobs, through investment in infrastructure, decarbonisation and maintenance projects. Improving the energy efficiency of buildings is a principle which is at the core of the Green New Deal. The Plan for Jobs includes similar proposals, such as:

  • a £2 billion Green Homes Grant scheme that will provide homeowners and landlords with vouchers to spend on improving the energy efficiency of homes across the UK;
  • a £1 billion Public Sector Decarbonisation Scheme that will offer grants to public sector bodies, including schools and hospitals, to fund both energy efficiency and low carbon heat upgrades;
  • a £40 million Green Jobs Challenge Fund for environmental charities and public authorities to create and protect 5,000 jobs in England.

Final thoughts

The concept of the Green New Deal is one that appears to evolve and shift as time goes on. This is unfortunately to be expected as time runs out for governments to take meaningful action to avert rising global temperatures. The transition to carbon neutrality is one that will undoubtedly result in massive changes to almost every aspect of our day-to-day lives, and therefore it is not surprising that the journey to reach this point may require bold and unprecedented action.

However, prior to the Coronavirus pandemic, it would have been unimaginable to consider the levels of spending and intervention that governments would be required to take in order to implement a Green New Deal. The shift to carbon neutrality involves a complete reimagining of the economy and requires a great deal of public support, in particular when the energy transition may threaten the jobs of those who work in carbon-intensive industries.

In a post-Covid era, the concept of governments spending huge sums of money and making unprecedented interventions is now our everyday reality. The economic consequences of the pandemic will require an extraordinary response to ensure that its legacy is not one of increasing levels of unemployment, inequality and stagnation. In this new world, the ambition and wide-ranging nature of the Green New Deal may no longer be seen as unfeasible. In fact, as can be seen in the UK and Europe, governments are already looking to implement various elements of the Green New Deal as part of their economic recovery packages. Perhaps the Green New Deal is about to have its time.

Build back better: is now the time for Green New Deals? – Part 1

From the signing of the Paris Climate Agreement to the pressure placed on governments by worldwide school strikes, the issue of climate change and its effects on the world around us has increasingly risen to the top of the political agenda. Across the world, governments have begun to take various forms of action in an attempt to prevent further rises in global temperatures.

In particular, the concept of a package of measures designed to address climate change and economic inequality, known as the Green New Deal, has gained particular prominence in the past few years.

This two-part blog looks at the concept of the Green New Deal, how it has influenced global policy and its relevance as a means of economic recovery in a post-Covid world.

What is the Green New Deal?

The original concept of a Green New Deal was proposed in a report published by the New Economics Foundation in 2008. The report set out a range of policy proposals that would allow the UK to recover from the global financial crisis, whilst tackling the threat posed by climate change. The scale and ambition of the Green New Deal was largely inspired by the wide-ranging New Deal package of reforms and investment carried out by President Roosevelt, that enabled the United States to recover from the Great Depression.

In a similar vein, the report made recommendations that addressed a wide range of policy areas,  these included:

  • a £50 billion per year programme to create a low-carbon energy system that will involve making “every building a power station” by maximising energy efficiency and renewable energy generation;
  • creating and training a “carbon army” of workers to provide the human resources required for a vast environmental restructuring programme;
  • re-regulating the domestic financial system to ensure that the creation of money at low rates of interest is consistent with democratic aims, financial stability, social justice and environmental sustainability;
  • minimising corporate tax evasion by clamping down on tax havens and corporate financial reporting.

Green New Deal: 2.0

Over time the Green New Deal has evolved and has spread internationally. Following the 2018 US Elections, the concept gained increasing prominence in the United States. Advanced by newly elected Congresswoman Alexandria Ocasio-Cortez and Senator Ed Markey, the Green New Deal set out a vision for the United States to transition to become carbon neutral in just ten years.

In a similar vein to the ambition of both the New Deal and the original Green New Deal, the package proposed included a variety of measures that crossed a range of policy areas, including:

  • meeting 100% of the power demand in the United States through clean, renewable, and zero-emission energy sources;
  • upgrading all existing buildings in the United States and building new buildings to achieve maximal energy efficiency, water efficiency, safety, affordability, comfort, and durability, including through electrification;
  • providing all people of the United States with high-quality health care; affordable, safe, and adequate housing; economic security; and access to clean water, clean air, healthy and affordable food, and nature;
  • guaranteeing a job with a family-sustaining wage, adequate family and medical leave, paid vacations, and retirement security to all people of the United States.

Criticism of Green New Deals

The concept of the Green New Deal is often criticised for being too expensive to be implemented. Opponents of the US Green New Deal believe the timeline for the United States to become carbon neutral in just ten years is unrealistic, and the estimated cost of  $12.3 trillion is too high. Critics also argue that the proposals are too vague and often fail to consider the seismic changes the measures may have on wider society, particularly for those who work in industries directly impacted by the energy transition.

In short, critics of a Green New Deal believe that as a package it is simply too large, both in ambition and price, to be implemented successfully. The level of government action required to implement such wide-scale reform would be unprecedented in peacetime and could potentially require citizens to make substantial changes to the way they live their lives. Until wider society is willing to accept a substantial increase in government spending and changes to their way of life, it is unlikely that a Green New Deal will be able to be effectively implemented.
