The United Kingdom introduced the Climate Change Act at the commencement of a recession. What people don’t appreciate is that it is legally binding in the UK that greenhouse gas emissions must fall by at least 80% by 2050.

The Act introduced a system of carbon budgets which provide legally binding limits on the amount of emissions that may be produced in successive five-year periods, beginning in 2008.

The first three carbon budgets were set into law in May 2009 and require emissions to be reduced by at least 34% below base year levels in 2020.

The fourth carbon budget, covering the period 2023–27, was set in law in June 2011 and requires emissions to be reduced by 50% below 1990 levels.

This report sets out the proposals and policies for meeting the first four carbon budgets. First carbon budget (2008–12), Second carbon budget (2013–17), Third carbon budget (2018–22), Fourth carbon budget (2023–27), Carbon budget level (million tonnes carbon dioxide equivalent.)
