Cost of Net Zero by 2050 less than a single fossil fuel price shock says Climate Change Committee

A new report from the Climate Change Committee (CCC) has found that the total additional cost of a single fossil fuel price spike of 2022 magnitude is likely to be as large as the total net additional cost of meeting the pathway to Net Zero across every year to 2050. In a separate analysis, the New Economics Foundation says that the 2026 shock could have far wider consequences than the 2022 crisis, while the UK economy is in a much weaker position to deal with it.
The CCC's report says that under all scenarios, achieving Net Zero is a more cost-effective path for the UK economy than continued reliance on fossil fuels, bringing a net benefit to society.
The report also includes additional cost-benefit analysis of the CCC’s proposed Balanced Pathway to Net Zero. This pathway was modelled for the Seventh Carbon Budget which the CCC presented to the UK Government in February 2025.
The Committee’s key findings are that for every pound spent on Net Zero, the benefits outweigh the cost by 2.2 to 4.1 times.
It says that the transition is also set to deliver far greater health and wellbeing co-benefits than costs. Cleaner air, warmer homes, more active travel and healthier diets strongly outweigh downsides like extra public transport time or potential congestion from increased EV use. These co-benefits are estimated to provide £2 billion to £8 billion per year in net benefit by 2050.
Nigel Topping CMG, Chair of the Climate Change Committee, said: “There has been a lot of public interest in the cost of transitioning to a low carbon economy. Going through an economic transition is exciting, but a sense of uncertainty about the future is completely reasonable. As such, it’s important that decision makers and commentators are using accurate information to inform debates.
“In light of current world events, it’s more important than ever for the UK to move away from being reliant on volatile foreign fossil fuels, to clean, domestic, less wasteful energy.”
In a related development, the cross-party Environmental Audit Committee (EAC) has published its response to the 7th Carbon Budget, saying that the costs of cutting emissions will be experienced early and unevenly, while benefits arrive later or are less visible; consequently, public consent for Net Zero can't be assumed.
The Committee also warns that mixed policy signals, including proposals to introduce pay-per-mile charging for electric vehicles, risk weakening public and investor confidence, while contradictory decisions such as airport expansion must be transparently reconciled with the pathway required to meet the UK’s legally binding environmental targets.
These misaligned choices signal that net zero is a “conditional ambition rather than a binding national obligation”, the Committee warns and would slow the uptake of low carbon technologies, deter investment and undermine confidence in Net Zero.
The EAC says that fairness is “fundamental” to delivering CB7, recommending that the Government address the imbalance between electricity and gas prices by removing appropriate policy costs from electricity bills and funding them through general taxation.
It also calls on the Government to publish an assessment of which groups are at risk of disproportionate costs, including workers whose jobs are displaced by the transition, and the measures in place to support them.
Toby Perkins MP, Chair of the EAC said: “Carbon Budget Seven is a pivotal moment in the path to cutting emissions to net zero. With the easy pickings of decarbonisation largely delivered, the measures still to come will impact our daily lives more than ever. How we travel, heat our homes and power our technology will all be affected.
"Public backing for net zero cannot be taken for granted. If CB7 is to succeed, it will be because it was affordable, convenient and attractive for the public, as well as environmentally necessary. To sustain confidence, the Government must renew its own commitment to affordability by addressing the structural imbalances that currently push up the cost of electricity.
"Ministers must also defend the net zero agenda explicitly and proactively, making clear how the Government as a whole is pushing towards a common goal. Cutting emissions to net zero is essential to preventing further climate change. The Prime Minister and Chancellor must make the case from the very heart of government."
The Government has two months to respond to the EAC's report.
