The opposition Conservative Party has released a report arguing that the UK should abandon its net-zero by 2050 target and related climate policies, claiming they burden the economy. The report, produced by the centre-right thinktank Onward and based on modeling by advisory firm Transira Energy, proposes an alternative policy pathway that would prioritize lower electricity costs through increased use of gas and nuclear power instead of renewables.
The Conservative argument centers on the claim that cheaper electricity would encourage adoption of electric vehicles and heat pumps, thereby increasing economic electrification while reducing emissions. Shadow energy secretary Claire Couthill contends in the report’s foreword that making electricity cheap should be the priority to drive emissions reductions. The Conservatives assert their approach could save over £320 billion compared to current policies.
However, expert analysis identifies significant flaws undermining these claims. The report’s own modeling shows the alternative scenario would result in 524 million tonnes of additional carbon dioxide emissions between 2030 and 2050, equivalent to South Africa’s annual emissions. This contradicts the central argument that the approach would reduce climate impact. Experts note the alternative pathway assumes lower overall electricity consumption despite claims about increased electrification, with only data centers seeing higher power demand due to policy prioritization.
Multiple credibility issues weigh on the analysis. The report relies on questionable assumptions about stable, low gas prices and assumes lower electrification targets, subsidies, and government mandates would not significantly reduce consumer adoption of electric vehicles and heat pumps. When adjusted with more realistic assumptions, experts indicate renewables rather than gas and nuclear would provide the lowest total costs. Additionally, the analysis excludes costs associated with replacing electric vehicles with petrol and diesel alternatives, estimated at £65-95 billion over two decades.
Energy analysts also question whether the proposed pathway would meaningfully improve the electricity-to-gas price ratio sufficiently to drive consumer adoption of heat pumps without continued subsidies or incentives. Overall, expert assessment suggests the report’s modeling contains fundamental flaws that reverse its central conclusions about cost savings and environmental benefits.
