The flaw in Rishi Sunak’s plan to water down net zero

Rishi Sunak will reportedly make a speech later this week watering down some of the targets the government has set itself on achieving net zero carbon emissions by 2050, although that target itself will not be touched).

The proposed ban on new petrol and diesel cars will be put back by five years to 2035, which would bring Britain in line with the EU. The ban on new oil-fired boilers will be put back from 2026 to 2035, thus relieving the Conservatives of the prospect of mass grumbling in one of their natural constituencies, rural areas. Even in 2035, it seems, the target will be to reduce installations only by 80 per cent, in recognition than many homes are difficult to bring up to the insulation standards required for heat pumps to work effectively.
