Greenhouse gas (GHG) emissions from agriculture, land use and land use change (ALULUCF) are a significant percentage of UK emissions. The UK Climate Change Act 2008 sets a target of achieving at least a 80% reduction in GHG emissions by 2050 relative to the 1990 baseline, and the Government has set carbon budgets for four five-year periods from 2008 to 2027, at levels recommended by the Committee on Climate Change. The CCC recommendations draw on the best available evidence, including the marginal abatement cost curves (MACCs) that have been developed for the ALULUCF sector.
The CCC recommended the level of the fifth carbon budget, covering the period 2028-32, in November 2015. In doing so, the Committee reviewed the latest evidence on abatement potential and costs across sectors. The aim of this study was to develop an updated MACC for the UK ALULUCF sector.
