Recommendation 5

There are a number of different estimates of the cost of achieving net zero by 2050. However, the Government has not yet committed to its own cost estimates and should set these out as soon as possible. The Government should include in the Net Zero Review final report its own methodology on costs; and it should set out clearly where the uncertainties lie. The Treasury should also include a range of scenarios on how net zero might be achieved, and the associated cost for each scenario.
