Revisiting the blue economy – a vital part of the world’s environment

This is the third in a series of republished blog posts from The Knowledge Exchange, revisiting important topics with ongoing relevance for public policy and practice, as well as for communities and wider society. This post covers the blue economy, focusing on why it is so important, the current challenges and what is being done to protect it. At the end of the republished article, we’ve updated the post to report on recent developments.

As the international community attempts to address the current ‘climate emergency’, increasing attention has been paid to the green economy. According to the United Nations (UN), “an inclusive green economy is one that improves human well-being and builds social equity while reducing environmental risks and scarcities.” Over the past decade, many governments have highlighted the green economy as a strategic priority, and since the Intergovernmental Panel on Climate Change (IPCC) published its special report on the impacts of global warming of 1.5 °C, action has been stepped up across the globe.

However, green economy strategies tend to focus on the sectors of energy, transport, agriculture and forestry, which leaves out a vital part of the world’s environment – the oceans. It has been argued that “a worldwide transition to a low-carbon, resource-efficient green economy will not be possible unless the seas and oceans are a key part of these urgently needed transformations”.

Perhaps unsurprisingly then, a new buzzword in the international sustainability agenda is gaining momentum – the ‘blue economy’. Since the turn of the 21st century, there has been an increasing commitment to growing the blue economy but what exactly is it and why is it important?

What is the blue economy?

Similarly to the green economy, there is no internationally agreed definition of the blue economy. Its origins stem from the Rio+20 outcomes whereby member states of the UN pledged to ‘protect, and restore, the health, productivity and resilience of oceans and marine ecosystems, to maintain their biodiversity, enabling their conservation and sustainable use for present and future generations.’

It is further explained through the UN General Assembly support for Sustainable Development Goal (SDG) 14: ‘Conserve and sustainably use the oceans, seas and marine resources for sustainable development’ as set out in the UN’s 2030 agenda for sustainable development.

Various definitions have been used by different agencies.

According to the World Bank, the blue economy is the “sustainable use of ocean resources for economic growth, improved livelihoods and jobs, and ocean ecosystem health.”

Conservation International has suggested that, “at its simplest, ‘blue economy’ refers to the range of economic uses of ocean and coastal resources — such as energy, shipping, fisheries, aquaculture, mining, and tourism. It also includes economic benefits that may not be marketed, such as carbon storage, coastal protection, cultural values and biodiversity.”

Like the green economy, the blue economy model aims for improvement of human wellbeing and social equity, while significantly reducing environmental risks and ecological scarcities.

Why is the blue economy so important?

Clearly, ocean health is vital to the blue economy. With over 70% of the world’s surface covered by ocean, almost half of the world’s population living in close proximity to the sea, the majority of all large cities being located along the coast and 90% of global economic trade travelling by sea, it is not difficult to see why the ocean and its resources are seen as increasingly important for both sustainable and economic development.

It is also a source of food, jobs and water, and contributes to the protection of the environment by absorbing carbon dioxide emissions. It has been estimated that the global blue economy has an annual turnover of between US$3 and 6 trillion and is expected to double by 2030. It is also estimated that fisheries and aquaculture contribute $US100 billion annually and about 260 million jobs to the global economy. In addition, over 3 billion people around the world, mostly from developing countries, rely on the world’s oceans and seas for their livelihood.

It is therefore not surprising that ocean pollution and the threat to marine resources have ascended the sustainability agenda in recent years, attracting increasing global attention and high-profile interest.

Sir David Attenborough’s popular Blue Planet II series highlighted the devastating impact pollution is having on the world’s oceans. It led to drastic behaviour change – 88% of people who watched the programme reported having changed their behaviour as a result, with half saying they had “drastically changed” their behaviour, and half saying they had “somewhat changed” it.

The recently heightened concerns over climate change have also highlighted the importance of the blue economy. The IPCC report warned that coral reefs would decline by 70-90% with global warming of 1.5°C, whereas virtually all (> 99%) would be lost with 2ºC.

Momentum building

Governments and organisations from across the world have been taking action to address the climate emergency with many strengthening commitments to growing the blue economy in particular.

The first ever global conference on the sustainable blue economy was held in 2018. It concluded with hundreds of pledges to advance a sustainable blue economy, including 62 commitments related to: marine protection; plastics and waste management; maritime safety and security; fisheries development; financing; infrastructure; biodiversity and climate change; technical assistance and capacity building; private sector support; and partnerships.

A new High Level Panel for a Sustainable Ocean Economy was also established in September 2018, the first time serving heads of government have joined forces on a global pact to protect the world’s oceans.

The UN’s Decade for Ocean Science (2021-2030) will also soon be upon us and the World Trade Organisation (WTO) has been tasked with ending harmful fisheries subsidies by 2020. New approaches are also helping countries value their small-scale fisheries. Scotland’s economic action plan, for example, makes a specific commitment to grow the blue economy which includes a new, world-leading approach to fisheries management with a focus on inclusive economic growth.

Way forward

The increasing awareness of the blue economy and the threats it currently faces provide an opportunity to change things for the better. As the global conference on the sustainable blue economy suggested, a sustainable blue economy strategy needs to be people-centric with ocean-centric investments. If momentum keeps building towards growing the blue economy across the globe, perhaps this will go some way to mitigating the global climate emergency bringing benefits for all.

What happened next?

Since this blog was first published in 2019, the world has been turned on its head by the global pandemic. But while COVID-19 has stopped many things in their tracks, the climate crisis is not one of them. The IPCC’s latest report has provided new estimates of the chances of exceeding the 1.5°C global warming level, warning that “unless there are immediate, rapid and large-scale reductions in greenhouse gas emissions, limiting warming to close to 1.5°C or even 2°C will be beyond reach.”

Of course, like so many others, the pandemic has also severely impacted blue economy sectors, which now need further support. The precise impacts of the disruption on the future of the blue economy remain unclear and it has been argued that building strategies that seek to maintain its potential pre-COVID will be challenging. However, the momentum that was building across the globe in committing to growing the blue economy has not halted.

We have now reached the UN’s Decade for Ocean Science (2021-2030) which provides a common framework to ensure that ocean science can fully support countries to achieve the 2030 Agenda for Sustainable Development.

The 14 world leaders of the High Level Panel for a Sustainable Ocean Economy have committed to sustainably manage 100% of the ocean area under their national jurisdiction by 2025.

Despite delays and constraints, progress has been made by the WTO on harmful fisheries subsidies, with the 12th Ministerial Conference now to take place from 30 November to 3 December 2021.

And following the Scottish Government’s commitment to growing the blue economy, it has since committed to developing a blue economy action plan which will take a joined-up strategic approach across the diverse range of Scotland’s established and emerging marine sectors to maximise the opportunities offered by its abundantly rich marine zone. It will also “seek to help marine sectors and coastal communities to recover from the COVID-19 crisis and grow sustainably whilst also supporting a transition through EU Exit.

If anything, the pandemic has succeeded in emphasising the enormity of the climate emergency and the action required to address it. And the world’s oceans still have a vital role to play in this fight.

As we approach COP26, often billed as our ‘last chance’, it is hoped that outcomes will include “greatly enhanced commitments and resources to meet the challenges presented by the ocean-climate nexus”.

Lift-off for the new space economy

Nearly Cloudless Scotland, As Seen From the ISS“Nearly Cloudless Scotland, As Seen From the ISS” by NASA’s Marshall Space Flight Center is licensed under CC BY-NC 2.0

It may come as a surprise to learn that Scotland is on its way to becoming a space industry superpower. The country is home to over 130 space businesses, with a combined annual income of £140m. Glasgow is building more satellites than any other city outside Houston.

Scotland’s booming space sector was the focus of a webinar that was part of last month’s Digital Leaders Week.  Leading the event was Tom Soderstrom, former Chief Technology and Innovation Officer at NASA/Jet Propulsion Lab, and current Global Lead for Chief Technologists at Amazon Web Services (AWS).

Tom explained that Scotland’s increasing involvement in the space sector is part of a wider growth in the ‘space-for-earth’ economy, which includes telecommunications and internet infrastructure, earth observation capabilities and national security satellites.

The factors driving the new space economy

Falling costs for building and launching spacecrafts have attracted greater investment in the commercial space industry. Space hardware is cheaper because it has become much smaller – these days, a miniature satellite (or ‘cubesat’) is typically about the size of a shoebox.

In recent years, the number and range of applications relying on satellite technology has rocketed. From smartphones and GPS devices to broadband access for developing nations, demand for space-based infrastructure has never been greater.

Data is another important driving force behind the new space economy. Scientists and governments need reliable data in order to understand how our planet is changing, and satellites can be used to take vital measurements of things like ice thickness coverage, deforestation, and ocean surface temperatures.

Cubesats are also used for monitoring shipping lanes, keeping a record of crop yields, and for protecting communities. Tom gave an example of an Australian company which uses satellite data for the early detection of wildfires, enabling emergency services to respond before lives and properties are put at risk.

Scotland’s place in space

Scotland is well placed to make the most of the booming space economy. According to Scottish Development International, operating costs for space companies are 40% lower in Scotland than elsewhere in the UK.

Another of the webinar participants, Professor Marion Scott from the department of mathematics at the University of Glasgow, highlighted the importance of Scotland’s skilled workforce. Nearly 20% of  all UK space roles are filled by Scotland’s 7,500 person strong talent pool. And Scottish universities have been quick to fill the gaps in different sectors by providing new courses, training and collaboration.

Meanwhile, Phil Cooper, AWS’ regional manager for Europe, the Middle East and Africa, pointed to the burgeoning reputation of companies in the Scottish space sector. AAC Clyde Space, for example, has become a market leader in providing spacecraft design, satellite operations and data delivery to governments, businesses and educational organisations.

But Scotland’s space boom is far from over. Phil forecasts that another 30 start-ups could be up and running by this time next year.

Another exciting prospect is the arrival of vertical launch capabilities. Five space hubs are currently under development around Scotland, and last year a site in Sutherland received planning permission from Highland Council to develop the UK’s first space port. By next year, it’s hoped that the vertical launch pad near Melness will send its first satellite into space.

Cosmic congestion: the problem of space junk

While there are lots of positives associated with the space economy, it’s not all good news. There are currently almost 7000 satellites orbiting the Earth, and the US National Oceanic Atmospheric Administration (NOAA) says that figure could double in 2021. As space becomes more congested, the problem of debris from old spacecraft and satellites has grown.

There’s a growing need for collaboration and internationally-agreed regulations to ensure that today’s satellites don’t become tomorrow’s space junk.

Tom Soderstrom highlighted research by Fujitsu, in collaboration with Astroscale, the University of Glasgow and AWS, to develop a proof of value to make space debris removal missions more commercially viable using its open innovation technology. The UK government has provided funds for this and other projects aiming to track space junk and monitor the risks of potentially dangerous collisions with satellites or even the International Space Station.

The space economy: tackling climate change

Environmental issues will be dominating the headlines later this year, when Glasgow plays host to the critical United Nations Climate Change Conference (COP26). One of the questions raised at last month’s webinar was how Scotland’s space sector can address the Earth’s climate challenges.

Marion Scott explained that there is now a network of universities and research centres working together to consider some of the climate challenges in advance of the COP26 meeting. At the same time, Marion stressed the importance of earth observation data in helping assess the scale of the problem of climate change.

Phil Cooper agreed that data was vital, and highlighted a competition launched by the Satellite Applications Catapult and the Commonwealth Secretariat in April which aims to stimulate discussion around the development of new concepts relating to ocean sustainability, incorporating satellite data and technologies.

The only way is up: the future of the space economy

In 2019, the World Economic Forum reported that while heavyweights like the United States, China and Russia have the greatest number of satellites in orbit, more and more nations – including the UK, Canada, Germany, Argentina and Luxembourg – have been developing their own space programmes. The Economist recently highlighted the growing number of African countries joining the commercial space race – last month the tiny Indian Ocean island of Mauritius became the latest country to launch its first satellite.

At the conclusion of the webinar, Phil Cooper expressed great optimism about the future of the space-to-earth sector, which can involve not only scientists, but people working in manufacturing, digital, marketing and many other industries. And, as Tom Soderstrom observed, the opportunities being generated by the new space economy are almost unlimited:

“The space bubble will grow faster than even I can imagine!”

Horizon Europe goes live

Horizon Europe is finally a reality. After months of false starts, soft launches and stalled negotiations, 22 June saw hundreds of funding calls published on the European Commission Funding and Tenders Portal. Researchers, institutions and other organisations can now access the seven-year, €95.5 billion research and innovation programme.

Horizon Europe is the ninth European Research and Innovation Framework programme (2021-2027). In the wake of the COVID-19 pandemic, it is one of the key instruments of the European Union’s efforts to steer and accelerate Europe’s recovery, preparedness and resilience.

The initial work programme covers the period 2021-2022 and consists of €14.7 billion in funding, which will be allocated based on competitive calls for proposals.

Around €5.8 billion in total will be invested in research and innovation to complement the European Green Deal and the EU’s commitment to become the world’s first climate-neutral continent by 2050. Supporting the EU’s goal of making the 2020s ‘Europe’s Digital Decade’, core digital technologies will receive around €4 billion over 2021-2022. Finally, direct investments of around €1.9 billion will be made towards helping repair the immediate economic and social damage brought about by the COVID-19 pandemic.

Mariya Gabriel, Commissioner for Innovation, Research, Culture, Education and Youth, said:

“With 40% of its budget devoted to making Europe more sustainable, this Horizon Europe work programme will make Europe greener and fitter for the digital transformation. Horizon Europe is now fully open for business: I would like to encourage researchers and innovators from all over the EU to apply and find solutions to improve our daily lives.”

Associated Countries: UK in, Switzerland out

Although the European Commission has yet to secure final agreements with non-EU countries on participation in Horizon Europe, a 17 June document revealed a list of 18 countries where association negotiations are ‘being processed or where association is imminent’.

The 18 provisionally associated countries are: Albania; Armenia; Bosnia and Herzegovina; Faroe Islands; Georgia; Iceland; Israel; Kosovo; Moldova; Montenegro; Morocco; North Macedonia; Norway; Serbia; Tunisia; Turkey; Ukraine; and the United Kingdom.

Most notably, while the UK is in, Switzerland has been excluded. Reports cite Swiss government officials as saying the European Commission did not give any notification of its intention to exclude the country from provisional access to Horizon Europe.

Writing on Twitter, Senior Policy Officer at the League of European Research Universities (LERU) Laura Keustermans described the move as not only bad news for Switzerland ‘but also very bad news for everybody involved in EU Research and Innovation’. LERU President Kurt Deketelaere also responded, urging the Swiss Government to work to gain access for the Swiss research and education sector, ‘which benefited greatly from association to EU programs in the past’.

UK Research and Innovation (UKRI) is urging researchers to start applying for Horizon Europe funding, with UK researchers and companies eligible for all Horizon Europe calls, apart from applying for equity funding from the European Innovation Council (EIC). The UK will also have to reach agreement with the Commission on rules for participating in sensitive projects in quantum and space technologies.

Free events mark programme launch

To mark the official opening of Horizon Europe, the European Commission arranged two free-to-air conferences for all citizens and stakeholders.

The European Research and Innovation Days, the Commission’s annual flagship Research and Innovation event, was held on 23-24 June. Policymakers, researchers, innovators, and other stakeholders took part in over 70 sessions and workshops to discuss the future European research and innovation landscape. Sessions included ‘tips and tricks’ for writing Horizon Europe proposals; an overview of the Commission’s Funding & Tenders Portal; discussions over lessons learnt from the COVID-19 pandemic; and an overview of the Africa Initiative in Horizon Europe. Recorded sessions from the event can be accessed via the event platform.

Running from 28 June to 9 July, the Horizon Europe Info Days will provide an in-depth overview of some of the main funding channels provided under Horizon Europe. The sessions will specifically focus on the six Clusters under Pillar II – Global Challenges and European Industrial Competitiveness, ­as well as the Marie Skłodowska-Curie Actions, Research Infrastructures, and Widening Participation and Strengthening the ERA (European Research Area) strands of Horizon Europe. With the exception of the Cluster 3 – Civil Security for Society session on 30 June, the event is open for participation without prior registration, and attendees will have the opportunity to ask questions, find out what is new in Horizon Europe and obtain further details about how the programme will operate. Interested parties can access the event’s online portal here.

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.
