A new report from the UK’s independent climate advisers suggests that the cost of reaching net zero by 2050 could be comparable to – or lower than – the impact of a single major fossil fuel price shock.
The analysis, published by the Climate Change Committee (CCC), also concludes that transitioning to a low-carbon economy would bring broader benefits, including economic savings, improved health outcomes and greater energy security.
Net zero costs compared with fossil fuel price shocks
The CCC report, released to complement its advice on the UK’s Seventh Carbon Budget, examined different economic and energy scenarios.
It found that the additional cost of reaching net zero between now and 2050 could be roughly equivalent to the economic impact of a single fossil fuel price spike – a sudden surge in the cost of oil, gas or coal, often caused by supply disruptions or geopolitical tensions – similar to the one experienced in 2022 following global supply disruptions.
In contrast, the analysis suggests that continued reliance on fossil fuels would expose the UK to repeated price shocks caused by geopolitical instability and volatile global markets.
Nigel Topping, Chair of the CCC, said that uncertainty around the economic transition is understandable but emphasised the importance of basing public debate on accurate information. He noted that shifting towards domestic, low-carbon energy could reduce exposure to volatile international fossil fuel supplies.
The costs and benefits of the net zero transition
According to the report, every £1 invested in the net zero transition could deliver between £2.20 and £4.10 in benefits.
Avoided climate damages account for the largest share of these benefits, which the CCC estimates could amount to between £40bn and £130bn in 2050.
The analysis also highlights improvements in the efficiency of the UK’s energy system. In a net zero scenario, energy losses would fall by about half compared with today’s system, reducing annual losses from around £60bn to £30bn.
Wider social benefits of the net zero transition
Beyond economic considerations, the transition is projected to deliver additional societal benefits.
Cleaner air, warmer homes, more active travel and dietary shifts could generate net health and wellbeing benefits of between £2bn and £8bn per year by 2050, according to the report.
These gains are expected to outweigh potential downsides such as increased public transport travel times or congestion linked to rising electric vehicle use.
How the findings could influence future UK policy
The findings form part of the evidence base for the UK’s Seventh Carbon Budget, which covers emissions between 2038 and 2042. The UK government is expected to respond to the CCC’s recommendations later this year.
The UK is legally committed to reaching net zero greenhouse gas emissions by 2050, with the CCC tasked with advising policymakers on the most effective pathways to achieve the target while supporting economic growth and energy security.
