The Conservative Party in the UK has put forward a report, developed by the Onward thinktank, that argues the country should abandon its net-zero by 2050 target in favor of pursuing cheaper electricity prices. The party contends that lower energy costs would make electric vehicles and heat pumps more attractive to consumers, ultimately supporting decarbonization while reducing financial strain on households. The report claims potential savings of over £320 billion through this policy shift.
However, the report’s own modeling undermines its central thesis. The alternative policy pathway described in the document would result in an additional 524 million tonnes of carbon dioxide emissions between 2030 and 2050, equivalent to the annual emissions output of South Africa. This outcome contradicts the Conservative argument that their approach would facilitate emissions reductions. Furthermore, the alternative scenario projects slower adoption of heat pumps and electric vehicles compared to current net-zero pathways, despite claims that lower electricity costs would drive consumer behavior toward electrification. Overall electricity consumption is projected to be 7 percent lower under the proposed alternative.
Experts identified numerous methodological issues with the report’s analysis. The modeling relies on questionable assumptions, including that gas prices will remain low and stable, and does not account for significant costs such as increased spending on petrol and diesel fuel to replace missing electric vehicles. The report also fails to include costs associated with accelerating data center grid connections, which receive priority under the proposed policy. Energy analysts note that the analysis does not demonstrate the electricity-to-gas price ratio would decline sufficiently to motivate consumer switching to heat pumps without government subsidies or regulatory requirements.
The report’s findings assume the removal of supportive policies such as the boiler upgrade scheme and the ban on new petrol and diesel car sales. Specialists in energy economics questioned whether the modeling adequately captures how falling electricity prices and reduced capital costs for electrification technologies would increase adoption rates. The analysis has been characterized as containing significant analytical gaps that fundamentally challenge the report’s anti-net-zero policy recommendations.
