How the UK Gov is Planning to Reduce 87% of GHGs before 2042

The UK Government has announced a new emissions reduction target that aims to deliver approximately 87% reduction in emissions between 2038 and 2042. 

The proposal builds on the country's long-standing commitment to climate action while supporting economic growth, energy security and lower household costs. 

As Britain continues its transition away from fossil fuels, the plan highlights the long-term benefits of clean, homegrown energy for families, businesses and future generations.

A more resilient low-carbon economy

The proposed Seventh Carbon Budget represents the next step in the UK's transition towards a cleaner and more sustainable economy. 

According to the UK Government, the target is designed to reduce the country's exposure to global fossil fuel price shocks while supporting long-term economic stability. 

The framework builds on the Climate Change Act 2008, which has helped attract billions of pounds in private investment and establish the UK as a leader in clean energy industries. 

Since July 2024, more than £90bn (US$121bn) of private investment has been announced in clean energy projects, including carbon capture developments in Teesside and the Sizewell C nuclear project. 

“As Britain faces the second fossil fuel shock of the decade, the only way to protect family and business finances is to drive for clean homegrown power that we control,” says Energy Secretary, Ed Miliband.

“What has been achieved so far by businesses and communities across the country is a great British success story - cutting costs by upgrading homes, backing British businesses, supporting one million good jobs according to new analysis from CBI Economics, and protecting our beautiful countryside.  

“Some people want to stick their heads in the sand and let our children face the consequences of climate breakdown - but this government believes in the timeless British value of protecting our country for generations to come.”

The government also highlights that the net zero economy supports over one million jobs and is expected to contribute £105bn (US$141bn) in gross value added to the UK economy in 2025.

“Another spike in gas prices shows the real cost of staying tied to fossil fuels. Reaching net zero won’t just protect the climate, it’ll help protect households, strengthen the economy, and safeguard the natural world we all rely on – and it will cost us less than one fossil fuel shock per decade,” says Rick Parfett, Head of Climate Policy at WWF.

“Our green economy is already a real success story, delivering growth in every part of the UK and supporting over a million jobs.    

“Today’s announcement should give businesses confidence to invest in a fair transition, backed by independent advice and the Climate Change Act, but we need clear, credible and ambitious policies to make that happen. 

“That means using the National Wealth Fund and GB Energy to help more people power their homes with clean energy, cut bills, and support nature’s recovery.”

Clean energy technologies

A key focus of the government's strategy is helping households reduce energy costs through the adoption of clean technologies. 

The proposed emissions target is based on a consumer choice-led approach that encourages the use of solar power, battery storage and EVs. 

March recorded the highest monthly solar deployment in more than a decade, alongside record EV sales. 

“The record-breaking May heatwave is another reminder that climate change is no longer a distant prospect. Increased heatwaves, flooding and nature loss are becoming the new norm for our country,” says Climate Minister, Katie White.

“That’s why we’re continuing to set a clear investment framework which will electrify Britain, maximising the benefits of clean power with cleaner air, warmer homes, energy security, investment into Britain and thousands of jobs in the industries of the future.”

Families installing solar panels could save up to £500 (US$672) annually, while EV owners could save up to £1,400 (US$1,884) a year in running costs. 

In addition, the £15bn (US$20bn) Warm Homes Plan aims to deliver the largest home upgrade programme in British history, helping to lower energy bills and reduce fuel poverty across the UK.

Energy security and supporting jobs

The government argues that accelerating the transition to clean energy is essential for improving the UK's energy security. 

“Every step forward on the energy transition is welcome but the prize is bigger than emissions alone. It’s the chance to transform a system built for a different century into one that works for customers where flexibility is rewarded, demand is dynamic and pounds end up back in people’s pockets,” says Chris Norbury, CEO of E.ON UK.

“Action now means lower bills and energy security all moving in the same direction.”

With half of the country's recessions since 1970 linked to fossil fuel shocks, reducing dependence on imported fossil fuels is seen as a critical economic priority. 

Recent renewable energy investments have secured enough clean power to supply the equivalent of 23 million homes, while long-term projections suggest the UK could reduce fossil fuel reliance from around 75% of energy use today to approximately 15% by 2050. 

“Moving away from our reliance on fossil fuels is critical to restoring nature in the UK. Our security, prosperity and wellbeing all rely on having a healthy natural world, and the good news is that nature can play a significant role in helping us to meet carbon targets,” says Kevin Austin, Director of Policy and Advocacy at the RSPB.

“Restoring peatland, planting native trees, speeding up the rollout of renewable energy and decarbonising the economy are all key to delivering the healthy ecosystems people and wildlife depend on.”

This transition is also expected to support over 400,000 additional jobs by 2030. Research cited by the government shows that net zero jobs are significantly more productive than the UK average and generate higher-than-average wages for workers.

Creating environmental and social benefits

Beyond economic advantages, the clean energy transition is expected to deliver substantial environmental and public health benefits. 

Cleaner air resulting from reduced fossil fuel use could prevent around 8,000 hospital admissions annually by 2050, easing pressure on the NHS and improving quality of life. 

Nature restoration efforts, including peatland recovery and woodland creation, are projected to generate around £50bn (US$67bn) in environmental benefits by mid-century through enhanced biodiversity, improved water quality and greater flood protection. 

The government also notes that climate change poses growing risks to food and water security, critical infrastructure and national stability if action is delayed. 

“The Committee is delighted that the government have accepted the CCC’s advised level for the Seventh Carbon Budget,” says Nigel Topping CMG, Chair of the Climate Change Committee.

“The lower-cost, energy-secure future is electric – so we hope to see the government plan to accelerate electrification, in particular by making electricity cheaper.   

“The government must make its own pathway; but investors, businesses, and trade unions can have confidence in the work that we have done to show this is a feasible yet ambitious approach to a more secure world. 

“We will continue to hold the government to account for how it delivers against its targets and celebrate the successes the country has achieved.”
