Fourth Carbon Budget

The Fourth Carbon Budget - Reducing emissions through the 2020s
- 7 December 2010

4th carbon budget report coverThis report sets the Committee's advice on the fourth carbon budget, covering the period 2023-27, as required under Section 4 of the Climate Change Act; the Government will propose draft legislation for the fourth budget in Spring 2011. In line with the required timetable, this report comes only two years after the first report, which recommended budgets for the first three periods. From now on budget advice reports will be delivered every five years.

This report joins up the detailed analysis that we have previously published on the path to 2020, with longer-term analysis of the path to 2050. It contains in depth analysis of the latest climate science, the international context and looks across sectors including power, surface transport, buildings, industry and agriculture.
