Countdown to Net Zero 2030:
The Race to Decarbonise London

Can London avoid climate change catastrophe
or are government actions hindering a green future?

In 2018, the Mayor of London, Sadiq Khan, declared a climate emergency and later set a target for London to produce no carbon emissions by 2030.

The science is clear, the world is on track for catastrophic temperature increases, unpredictable weather patterns, extreme biodiversity loss, and a breakdown of our natural systems.

In 2023, record temperature highs were continuously set, while storms, floods, droughts, and heatwaves caused devastation.

These growing climate change impacts point to the need to urgently increase efforts to rapidly cut greenhouse gas emissions, safeguard natural environments, and protect vulnerable people.

However, despite these dire circumstances, according to the United Nations Adaptation Gap 2023 report, progress on adaptation to climate change is slowing.

“There is no person or economy left on the planet untouched by climate change, so we need to stop setting unwanted records on greenhouse gas emissions, global temperature highs and extreme weather.
We must instead lift the needle out of the same old groove of insufficient ambition and not enough action, and start setting other records: on cutting emissions, on green and just transitions and on climate finance.”
Executive Director of the United National Environment Programme Inger Andersen

Climate change is the process of long-term shifts in temperatures and weather patterns, mainly caused by human activities.

As greenhouse gas emissions rise they blanket the Earth and trap the sun's heat inside. With nowhere for the heat to escape, it stays in the atmosphere and slowly warms the globe.

The world is now warming faster than at any point in recorded history. These warmer temperatures are changing weather patterns and disrupting the natural balance of nature.

The biggest source of greenhouse gas emissions is burning fossil fuels such as coal, oil, and gas.

Emissions need to be reduced drastically and rapidly to mitigate the worst effects of climate change.

Under the 2015 Paris Climate Agreement, countries pledged to limit global warming to below 2 degrees but to preferably stay within 1.5 degrees, compared to pre-industrial levels.

Pre-industrial levels refers to the period of time before the Industrial Revolution when our climate was at its most stable as fossil fuel use was minimal.

Scientists have identified 1.5 degrees of warming as a key tipping point beyond which the chances of extreme flooding, intense heatwaves, drought, wildfires, water scarcity, and food shortages will increase dramatically.

According to a United Nations report, temperature rises over 2 degrees would bring even more catastrophic and potentially irreversible impacts, including pushing three billion people into chronic water scarcity.

The Mayor of London created an ambitious goal of achieving net zero carbon by 2030 to limit the worst effects of the climate emergency and stay within the 1.5 degree threshold.

While ambitious, it is not unachievable.

“We know it is still possible to make the 1.5 degree limit a reality. It requires tearing out the poisoned root of the climate crisis: fossil fuels. And it demands a just, equitable renewables transition.”
Secretary-General of the United Nations Antònio Guterres

Net zero carbon is a similar practice to carbon neutral but expanded in scale and effort.

While carbon-neutral refers to balancing out the total amount of carbon emissions, net-zero carbon means no carbon was emitted from the get-go, so no carbon needs to be captured or offset.

For example, a company's building running entirely on solar and using zero fossil fuels can label its energy as “zero carbon.”

This is a much loftier target than being carbon neutral.

To reach his net zero carbon goal, the mayor desperately needs the support and action of London councils.

To help track councils' progress toward reaching net zero carbon, Climate Emergency UK created Council Climate Action Scorecards.

Five years after the climate emergency declaration, how are London councils shaping up in the fight against climate change?

The effects of global temperature rises are already being felt and we haven't even reached 1.5 degrees of warming yet.

According to data provided by a range of organisations such as NASA, MetOffice, and the National Oceanic and Atmospheric Administration, the 10 hottest years on record have all occurred since 2010.

The science has never been more clear, we're heading towards catastrophic temperature rises that are of our own making.

We still have time to limit global warming but we need to act now.

What are Council Climate Action Scorecards?

Climate Emergency UK, an organisation that works within the climate sector at the council level, created Council Climate Action Scorecards to effectively score how well UK councils are progressing in achieving net zero carbon by 2030.

The nationwide data exercise is the first-ever assessment of climate action across all UK councils and all council functions.

The questions and information used in the scorecards were gathered over nine months in consultation with over 80 organisations and experts in the climate sector such as Friends of the Earth and Ashden.

The scorecards consist of publically available data, national data, local data, and over 4,000 Freedom of Information responses from UK councils covering multiple areas of climate action.

The information was then scored against the following seven categories of climate action:

  • Buildings & Heating
  • Transport
  • Planning & Land Use
  • Governance & Finance
  • Biodiversity
  • Collaboration & Engagement
  • Waste Reduction & Food

Councils gained points by taking actions that reduced carbon emissions in the seven categories in their area.

If a council was not taking action or had implemented something that increased current carbon emissions, they would instead have points deducted.

A higher percentage means the council has implemented successful measures that see greenhouse gas emissions reduced in that area.

You can see how well (or not) UK councils are doing here.

The scorecard results are a much-needed wake-up call on climate action, with only 41 out of 318 councils scoring 50% or higher.

Westminster

Westminster City Council is an inner city borough in London with a population of 205,087 (Census 2021).

According to Trust for London, Westminster has a poverty rate of 43% which is very high compared to the average (26%) of all London boroughs.

Westminster's council is labour and led by Councillor Adam Hug.

Westminster City Council had the best Council Climate Action score of 62% out of 318 UK councils. What have they done to achieve this?

Over the last two years, Westminster has had some great achievements towards decarbonisation. However, it also acknowledges that there is much more to do and it wants to be as ambitious as possible.

Westminster City Council has installed energy conservation measures in 61 council buildings, cutting corporate property emissions by around 1,700 tonnes of CO2 equivalent per year.

It has improved 450 council homes with energy efficiency measures and clean heating systems and invested £58m from the council pension fund into renewable energy infrastructure.

Westminster City Council has also launched the Responsible Procurement Strategy to put greater emphasis on sustainability within supplier contracts, holding business to account.

Over 1,500 electric vehicle charge points have been installed across the borough as of March 2023 to promote the shift away from fossil fuel-dependent vehicles.

Westminster actively includes its community in the fight against climate change through the creation of the Citizens’ Climate Assembly, where residents are randomly selected to help inform climate decision-making in Westminster, and the Resident Research Panel, a newly established panel of representative residents who participate in research to provide feedback on climate work.

Two areas which need improvement are Biodiversity and Waste Reduction & Food.

Westminster City Council is already taking steps towards a better score in Waste Reduction & Food by expanding food waste recycling across the borough.

Its biodiversity score could easily be increased by a dedicated tree planting campaign to provide more shade or by mowing green spaces less regularly and planting native wildflowers to encourage wildlife to return.

Westminster is leading the way towards net zero carbon by 2030!

Hammersmith & Fulham

The London Borough of Hammersmith and Fulham is an inner city borough in west London with a population of 183,200 (Census 2021).

According to Trust for London, Hammersmith and Fulham has a poverty rate of 18%, below average (25%) compared to all London boroughs.

Hammersmith and Fulham's council is labour and led by Councillor Stephen Cowan.

Hammersmith and Fulham came in second place out of the 32 London Councils with a score of 60%, closely followed by Merton.

Hammersmith and Fulham is taking great steps towards achieving net zero carbon by 2030 with category scores in the mid to high ranges that could easily be improved in the following years.

They have put a large focus on switching from fossil fuels to sustainable energy with all council buildings being powered by 100% renewable electricity.

They have introduced community electrical repair sessions and a Library of Things so residents can repair and borrow, rather than buy new to avoid wastage.

Hammersmith and Fulham has provided seed funding to establish a new community benefit society, Hammersmith & Fulham Community Energy (HFCE). It will continue to support this co-op by identifying council roof spaces and other assets for community investment in solar panels.

One area in which it does extremely well is Collaboration and Engagement. This means it includes the community and local organisations in climate change actions as well as provides education.

Where Hammersmith and Fulham falls short is with its many mid-ranged categories. Scores could be improved in Biodiversity by turning off or dimming their street light network to reduce light pollution or in Land & Planning by requiring new homes to be operationally net zero with the policy implemented from 2030 to 2040.

There is good momentum behind Hammersmith and Fulham's climate action with room for improvement heading into 2024.

Bexley

The London Borough of Bexley is an outer borough in south-east London with a population of 246,543 (Census 2021).

According to Trust for London, Bexley has a poverty rate of 26% which is average (25%) compared to all London boroughs.

Bexley's council is conservative and led by Councillor Teresa O’Neill.

Bexley has implemented climate change action into its council action plan, but is it enough and what has been achieved so far?

Bexley was the best London borough for recycling for 17 years and has a 50% recycling rate.

Unfortunately for Bexley, Bromley took the recycling crown this year to become London's top recycling borough.

According to Bexley's Action Plan, it has made an 84% reduction in CO2 emissions from 2015-2022 simply by upgrading its street lights to energy-efficient LEDs.

It has also planted 13,500 trees on the borough's highways and council staff moved into a more energy-efficient building.

While Bexley Council is taking small actions to reduce its borough's emissions, there is a clear gap where more needs to be done.

Transport is an area where Bexley falls short. Being an outer suburb, Bexley has a lack of modern public transport links, no underground stations, no access to the Docklands Light Rail, and no rapid bus services. Extending these services needs the backing of the Government.

Bexley also rejected the proposal to increase London's Ultra Low Emissions Zones. It believes it is an unlawful policy due to the installation of TFL-owned cameras to monitor the area and ULEZ
road usage taxes for non-compliant cars.

Cllr O'Neill called the ULEZ "the Mayor's money making scheme."

"The residents of Bexley gave us a clear mandate to oppose Mayor Khan's proposal to expand the ULEZ. It was never about air quality and we believe it would have disastrous consequences for many of our residents and businesses, as well as others who regularly travel into the borough."

When approached for comment about Bexley's climate actions, a spokesperson for the London Borough of Bexley responded that they believe the data captured in the Climate Scorecards does not give an accurate picture in Bexley.

Bromley

The London Borough of Bromley is an outer borough in south-east London with a population of 330,000 (Census 2021).

According to Trust for London, Bromley has a poverty rate of 17%, below average (25%) compared to all London boroughs.

Bromley's council is conservative and led by Councillor Colin Smith.

Bromley had the worst Council Climate Action score of 26% out of 32 London councils. What have they done to achieve this?

In 2022 Bromley set out to achieve a net zero council by 2027, three years ahead of the current 2030 goal.

However, according to Bromley's scorecard, there seems to be little action in achieving this goal borough-wide.

Bromley has not released a climate action plan that outlines how it will achieve net zero across the whole borough. Instead, it has an organisational plan which aims to only reduce the council's emissions.

Bromley was also one of the five councils involved in opposing the ULEZ expansion into the outer suburbs with the main reasoning being the installation of cameras and road chargers.

"Our borough is already a healthy borough by virtually every measurement, with the truth about the longer term intentions of the enforcement cameras, that of road price charging for all, now slowly but surely being dragged out into the open for all to see."
Councillor Colin Smith

All is not lost in Bromley, it was awarded the top borough for recycling in 2023 by recycling nearly 50% of their waste.

It has also made a 21% reduction in emissions from streetlights (2018/19 baseline) by the replacement of 3,638 old lanterns with energy-saving LED lanterns.

Bromley is taking small steps towards the right direction, however, a stronger stance and a borough-wide action plan are needed to make sure it can achieve net zero carbon by 2030.

Bromley did not reply when approached for comment about their Council Climate Action Scorecard or climate action plan.

Why is more not doing more?

While climate change is a pressing issue, councils have other priorities that see funding and resources needed elsewhere as well as barriers from the national government, and conflicting views on climate change policies.

One such policy that sees kickback from conservative-led councils is the expansion of Ultra Low Emissions Zones (ULEZ).

Poor air quality, mainly caused by polluting vehicles, is impacting the health of Londoners. To combat this, ULEZ were created.

ULEZ aims to help improve air quality by reducing the number of vehicles in London that don't meet emissions standards.

Vehicles that use these zones and do not meet the emissions standards or have exemptions will be charged a daily road usage tax of £12.50.

According to the Inner London ULEZ One Year Report, the ULEZ has already helped to reduce harmful nitrogen dioxide pollution by nearly half in central London and a fifth in inner London.

The expansion of the ULEZ to all London boroughs is due to these successes and the fact that the greatest number of deaths related to air pollution occur in outer London areas.

However, five conservative councils in outer London claimed that the ULEZ expansion was an unlawful money-making scheme that would unfairly affect lower-income households.

The five councils challenged the legality of the expansion in the High Court but lost after the ruling in July determined there was no legal impediment to the expansion, with the judge stating the mayor's expansion decision "was within his powers".

The case cost the five councils £230,941 in disbursements and £500,000 in legal costs to Transport for London.

A climate change plan needs to be developed where all authorities can achieve the goals set out. It needs to be backed by (peer-reviewed) clear, scientific evidence which can not be debated or misconstrued by those who do not believe in climate change.

Most importantly, a large boost of funding for sustainable projects is desperately needed to achieve net zero carbon by 2030.

Many councils report that the biggest barriers to implementing meaningful change and sustainable options are national government policies and inadequate funding.

According to Climate Emergency UK, 169 out of 388 UK councils have lobbied the national government calling on them to take further climate action or to provide further funding, powers, and climate resources so that councils
can take action themselves.

The national government are roadblocking climate action by rolling back on net zero policies, signing off on new oil and gas deals, and not giving authorities the resources and funding needed to implement long-lasting, sustainable changes despite urgent calls from councils, organisations, and experts.

Sunak has faced criticism for claiming that net zero ambitions will still be met while rolling back on multiple green policies, including delaying the deadline on the sale of new diesel cars.

One recent rollback by the Conservative Government was the scrapping of the "seven bins" policy.

A policy which did not seem to exist until Sunak scrapped it.

Addressing the confusion around the seven bins policy, Sunak said he would “never impose these unnecessary and heavy-handed measures on [households]”.

The fabled "seven bins" policy is actually part of the Consistent Recycling Collections strategy outlined in the Environment Act, which would see separate bins for different categories of recyclables to help increase the recycling rate.

It never stated that households would need seven different recycling bins. Instead, it outlined a need for a more standardised recycling approach that incorporated all recyclable categories such as glass, paper, hard plastic, etc.

Defra issued communications that said: "It was never the case that seven bins would be needed by households, this new plan ensures."

The new plan is the Simpler Recycling scheme where all recyclables are to go in the same bin and will later need to be separated at a waste facility.

This flip-flopping and uncertainty from the Government is causing frustration for many trying to achieve sustainability goals set out by the government such as the 65% municipal recycling rate by 2035 target.

UK’s second largest waste and recycling authority, North London Waste Authority (NLWA), expressed concerns that the Government’s announcement is another tactic to delay meaningful action to support increases in domestic recycling.

NLWA had already spent resources on developing a waste collection strategy in line with the Consistent Recycling Collections guidelines.

NLWA chair and Waltham Forest councillor Clyde Loakes said: “The government proposed its consistent collections reforms in 2018 and even now – a tortuous five years and four Secretaries of State later – many important details are still unclear."

“The government is at least consistent on being inconsistent when it comes to action to improve recycling, with constant dither and delays."

Slow action on implementing successful climate change policies by the Government is leading to frustration and increased fear for what kind of world future generations will inherit.

Executive Director of the United National Environment Program Inger Andersen stated: “In 2023, climate change yet again became more disruptive and deadly: temperature records toppled, while storms, floods, heatwaves and wildfires caused devastation.”

“These intensifying impacts tell us that the world must urgently cut greenhouse gas emissions and increase adaptation efforts to protect vulnerable populations. Neither is happening.”

The Climate Change Committee reported that net zero carbon can only be achieved if Government, regional agencies, and local authorities work seamlessly together.

With such an ambitious task and not every player on the same team, success is not in plain sight.

The Accelerated Green

Pathway Explained

The Accelerated Green Pathway was introduced by the Mayor of London Sadiq Khan in 2022 and showed London the way to a decarbonised future by 2030.

The Mayor has committed to bringing London’s net zero carbon target forward from 2050 to 2030.

The urgency of a net zero 2030 target means that much more substantial action must be taken now.

To help guide this process, the Mayor selected the Accelerated Green Pathway. A pathway which balances decarbonisation ambition with deliverability.

The Accelerated Green Pathway will reach 22% residual emissions by 2030 and achieve 10% residual emissions in the late 2030s.

Residual emissions are carbon emissions which still remain at the point of net zero, despite substantial efforts.

Achievement of the Accelerated Pathway requires a large-scale behaviour shift towards sustainable practices and an ambitious technology rollout that does not require widescale scrappage of old technology.

To reach net zero carbon by 2030, the Mayor will need to achieve a long list of requirements, such as:

  • A nearly 40% reduction in the total heat demand of our buildings, requiring over 2 million homes and a quarter of a million non-domestic buildings to become properly insulated
  • 2.2 million heat pumps in operation in London by 2030
  • 460,000 buildings connected to district heating networks by 2030
  • A 27% reduction in car vehicle kilometers travelled by 2030
  • Fossil fuel car and van sales ended by 2030 and enforced in line with the Government’s existing commitments

Ealing Councillor and London Councils’ Environment Committee Chair Deirdre Costigan stated that there are great opportunities for investment in net zero, green jobs, and growth but commitment over the next two years is critical.

"Choices made in London today about urban infrastructure, upskilling workers and supporting communities to live more sustainably will determine the extent and impact of the climate emergency across our capital.”

Has any progress been made since the roll-out of the Accelerated Green Pathway?

The Mayor of London announced a £500m fund to help organisations achieve net zero by 2030.

The Green Finance Fund will support projects delivering benefits in either energy efficiency, clean transport or renewable energy and is open to organisations in the GLA Group, any of London’s 32 local authorities, social housing providers, NHS bodies, universities and colleges.

Successful schemes to make the capital more energy efficient are set to save more than 50,000 tonnes of carbon in 2024 – equivalent to nearly 85,000 flights from London to New York – the Mayor revealed.

The introduction of the Low Carbon Accelerator programmes are helping to support schools, councils, and the NHS to address both the climate and cost of living emergencies by making their buildings more energy efficient and better heated.

New data shows the programmes will continue to save around 170,000 tonnes of carbon emissions annually before 2030. 

A great start to the pathway of net zero carbon 2030 however, there have been some major setbacks.

The national government has since u-turned on its policy to end fossil fuel car and van sales by 2030, pushing it back to 2035 in what Prime Minister Rishi Sunak described as “a new approach to achieving net zero.”

New policies that required landlords to upgrade the energy efficiency of their properties has also been scrapped, stating that the UK is over-delivering on reducing emissions.

These are just a few of the many green initiatives that Sunak has scrapped this year while claiming that the Government was still committed to reaching net zero carbon emissions by 2050 but in a "more proportionate way."

The Government then shifts the climate change onus onto the public by stating: "The Prime Minister has made clear that the plans to meet net zero will only succeed if public support is maintained or we risk losing the agenda altogether, unable to meet our goals."

This dangerous mindset forces the public to call for sustainable action to avoid global warming rather than holding the businesses and governments that produce and control the most emissions accountable.

Sunak claims that there are two extreme sides to the climate change debate, one that calls for too much change, and one that does not do enough.

With the signing of new oil and gas licenses, which scientists have consistently warned should not be done to avoid 1.5°C of warming, it seems like Sunak is on the latter side.

Oil Change International’s latest research shows that 60% of fossil fuels in existing fields must stay in the ground to limit global temperature rise to 1.5°C.

"The Mayor has been clear that in order to achieve
net zero by 2030 the Government needs to step up.
He has urgently called on ministers to provide more
funding and powers to mayors and local authortities."
A spokesperson for the Mayor of London

The Mayor can’t deliver net zero carbon emissions in London on his own by 2030.

Many measures will rely on national-level decisions and coordinated action with relevant councils and organisations, as well as engagement and behaviour change by the public and local businesses.

Everybody must be on board with decarbonising London to achieve net zero by 2030, help mitigate the worst effects of climate change, and stay within 1.5°C of global warming.

If you're reading this and feeling discouraged about the future - fear not! There is plenty that you can do to help.

While it may feel like some councils are not doing enough, the information on the Council Climate Action Scorecards can be used to urge change within your local council and community.

After all, according to the Climate Change Committee’s Local Authorities and the Sixth Carbon Budget Report:

“More than half of the emissions cuts needed rely on people and businesses taking up low-carbon solutions – decisions that are made at a local and individual level. Many of these decisions depend on having supporting infrastructure and systems in place.
Local authorities have powers or influence over roughly a third of emissions in their local areas.

Other ways to directly help:

  • Message your local MP
  • Create or join community action
  • Reduce, reuse, recycle, and repair
  • Buy from local businesses
  • Shop at authenticated b-corporation businesses
  • Reduce plastic use
  • Eat less meat products
  • Reduce food wastage
  • Reduce reliance on fossil fuels
  • Protest
