Climate Change Act 2008

The Climate Change Act 2008 (c. 27) is an act of the Parliament of the United Kingdom. The act makes it the duty of the secretary of state to reduce net greenhouse gas emissions, toward avoiding dangerous climate change. The act aims to enable the United Kingdom to become a low-carbon economy and gives ministers powers to introduce the measures necessary to achieve a range of greenhouse gas reduction targets. An independent Committee on Climate Change was created under the act to provide advice to UK Government on these targets and related policies. In the act 'Secretary of State' refers to the Secretary of State for Energy and Climate Change.

The original target was an 80% reduction by 2050 but in June 2019 this was strengthened to a "net zero" target of 100% reduction.
