This report advises on the level at which Welsh interim carbon targets and Welsh carbon budgets should be set. It comes in response to a request from the Welsh Government to the Committee for independent advice on these targets.

The Committee’s advice takes into account specific factors relating to the Welsh economy and its sources of emissions.

The report was updated on 14 February 2018 to correct an arithmetic error in the original version. This relates to the recommended emissions reduction target for 2020 if the Aberthaw power station closes before 2020, and to the recommended level of the first carbon budget in the case that Aberthaw closes before 2018.

• The level of the 2020 target if Aberthaw closes before 2020 was  previously stated as -34%. This has been corrected to -32%.
• The level of the first carbon budget if Aberthaw closes in 2018 was previously stated as -26%. This has been corrected to -25%.
