Cost of net zero by 2050 less than a single fossil fuel price shock – CCC

The cost of net zero by 2050 is less than a single fossil fuel price shock, says analysis by the Climate Change Committee (CCC). 

The CCC’s supplementary analysis complements the body’s advice on the UK’s Seventh Carbon Budget, which tests the committee’s cost and energy security conclusions against different scenarios.

The independent, statutory body tested its cost and energy security conclusions against different scenarios. It 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 all scenarios, achieving Net Zero was found to be 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 advice the CCC gave the UK Government in February 2025. This is carried out in line with the government’s Green Book guidance.  

The committee’s key findings are: 
    •    For every pound spent on net zero, the benefits outweigh this by 2.2 to 4.1 times. 
    •    Avoiding climate damages is the most significant benefit of the transition. This saving is estimated between £40 billion and £130 billion in 2050. 
    •    Energy losses are halved compared to today. Losses in a net zero system are valued at £30 billion per year, compared to £60 billion a year in today’s energy system. 
    •    The transition is 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.  
 
The CCC found that other wellbeing and health benefits – such as cleaner air, warmer homes and more active travel – outweigh issues around additional public transport time or potential congestion from more electric vehicles (EV).

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.” 

Responding to the CCC analysis, Gareth Redmond-King, head of international programme at the Energy and Climate Intelligence Unit (ECIU) said: “The last fossil fuel energy crisis, when Russia invaded Ukraine, cost the UK £183 billion over four years. As the next one unfolds, it’s worth remembering that renewable alternatives to gas are cheaper and quicker to build, and that last year British windfarms cut wholesale prices by almost a third.

“Electric vehicles are also cheaper than petrol and diesel ones to own and run even when oil prices are not soaring, saving their owners hundreds of pounds a year. And now we know that the cost of getting the UK to net zero – the only solution we have to halting climate change – is less than the cost of a single fossil fuel price shock. As the world faces yet another fossil fuel crisis, it is clearer than ever that a clean technologies offer a less costly, and more energy secure future.”
