Carbon dioxide emissions covered by the UK’s emissions trading scheme (ETS) in the first year of operation in 2021 were 107.8 million tonnes, according to the UK ETS Authority.
The UK ETS is a system designed to incentivize major polluters to lower emissions by compelling them to purchase permits to emit carbon dioxide. The scheme came into operation on January 1, 2021, following the UK’s departure from the European Union and its withdrawal from the EU’s emission trading system.
