The CCC undertakes an annual assessment of whether the UK is on course to meet its carbon budgets, and reports this progress to Parliament. The Committee also reports on Scotland’s progress in reducing greenhouse gas emissions against its annual carbon targets. This includes tracking the latest emissions data and identifying underlying progress, as opposed to reporting on fluctuations related to temporary factors (e.g. the weather).
UK emissions were 43% below 1990 levels in 2017. The first carbon budget (2008-12) has been met and the UK is currently on track to outperform the second (2013-17) and third (2018-22) carbon budgets, but is not on track to meet the fourth, which covers the period 2023-27.
Meeting future carbon budgets and the UK’s 2050 target to reduce emissions by at least 80% of 1990 levels will require reducing domestic emissions by at least 3% per year. This will require existing progress to be supplemented by more challenging measures.
The CCC has developed indicators to track emissions, progress in low-carbon investments, and the development of government policies. This allows early identification of any areas where targets could be missed. Some of the indicators we track include:
- Emissions in an average unit of electricity – and how low this could go if we used our existing power infrastructure differently.
- Size of onshore and offshore wind farms at various stages of the project cycle.
- Emissions from new cars and the rate of development in electric vehicles market.
- The number of lofts and walls being insulated and boilers upgraded, including moves to low-carbon heat such as ultra-efficient heat pumps.
- Progress of government policies such as grants for electric vehicles and Electricity Market Reform.
