The UK Climate Assembly is a citizens' group formed in the United Kingdom in January 2020 whose goal was to issue recommendations for how the UK could satisfy its climate change law—the Climate Change Act amendment passed on 27 June 2019 mandates that the country must reach net-zero carbon emissions by 2050. It was formed of 108 UK citizens, chosen to be representative of the population. Its last meeting was delayed to May due to the COVID-19 pandemic and the group's report was published in September 2020.
