Net Zero (legal commitment)

The Climate Change Act commits the UK government by law to reducing greenhouse gas emissions by at least 100% of 1990 levels (net zero) by 2050. This includes reducing emissions from the devolved administrations (Scotland, Wales and Northern Ireland), which currently account for about 20% of the UK’s emissions. The 100% target was based on advice from the CCC’s 2019 report, ‘Net Zero – The UK’s contribution to stopping global warming’.
