The Committee on Climate Change is an independent non-departmental public body, formed under the Climate Change Act (2008) to advise the UK and devolved Governments and Parliaments on tackling and preparing for climate change. The Committee provides advice on setting carbon budgets (for the UK Government carbon budgets are designed to place a limit or ceiling on the level of economy-wide emissions that can be emitted in a five-year period), and reports regularly to the Parliaments and Assemblies on the progress made in reducing greenhouse gas emissions.
The Committee on Climate Change was formally launched as a statutory committee in December 2008 with Lord Turner as its chair.
An Adaptation Sub-Committee was set up in 2009 to provide advice to Government about adaptation, meaning the steps the government and devolved administrations of the United Kingdom should be taking to prepare for climate change impacts.
On 1 December 2008 the committee published its first major report entitled "Building a low-carbon economy – the UK’s contribution to tackling climate change". This recommended that the UK adopt a long-term target to reduce emissions of all greenhouse gases by at least 80% by 2050, in order to tackle climate change. It recommended the level of three five-yearly carbon budgets to cover the periods 2008-2012, 2013-2017 and 2018-2022.
In line with the recommendations in the Committee's report, in April 2009 the Government set a requirement for a 34% cut in carbon emissions by 2020.
In December 2010 the Committee recommended a 4th Carbon Budget to cover the period from 2023 to 2027. They recommended that the Government aims to cut emissions by at least 60% by 2030 to ensure that the UK is on track to meet the 2050 target, with Parliament to debate the contents and proposals of this report before the summer's recess. A recommendation on the 5th Carbon Budget was published in November 2015 and adopted by the UK Government on 30 June 2016.
In addition to reports to advise on the level of carbon budgets, the CCC also provides annual progress reports to Parliament which provide an update on Government's progress towards meeting climate targets. The CCC has published Progress Reports for 2009, 2010, and every year since. The first biennial joint progress report from the Committee on Climate Change and the Adaptation Sub-Committee was presented to the UK Parliament on 30 June 2015. The joint progress reports include an assessment of the UK Government's National Adaptation Programme by the Adaptation Sub-Committee.
