A carbon budget places a restriction on the total amount of greenhouse gases the UK can emit over a 5-year period. The UK is the first country to set legally binding carbon budgets.
Under a system of carbon budgets, every tonne of greenhouse gases emitted between now and 2050 will count. Where emissions rise in one sector, the UK will have to achieve corresponding falls in another.
1. Setting of the first to third carbon budget
2. Setting of the second carbon budget credit limit
3. Setting of the third carbon budget credit limit
4. Setting of the fourth carbon budget (2023-2027)
5. Setting of the fifth carbon budget (2028-2032)
The Government has agreed with the Committee on Climate Change and set the fifth budgetary period covering 2028 to 2032 at 1,725 MtCO2e.
Policies and proposals to meet carbon budgets
In 2011, the Government set out scenarios on how it is going to meet the first four carbon budgets from 2008-2027.
