Opencast coal extraction causes extensive damage to local environments by opening up the land like a quarry, destroying habitats and polluting the air and water. Imported coal, from Russia, Venezuela, Colombia, the USA and Australia, also carries significant environmental and human rights impacts.

As of April 2023, the UK has two opencast coal mines in South Wales, with Ffos-y-fran currently producing coal outside of planning control whilst an application to extend it is pending, and Glan Lash apparently dorment with an extension also pending.

There are two potential sites for new underground coking coal mines. West Cumbria Mining Ltd and NAE want to extract millions of tonnes of coking coal a year from sites in Cumbria and the Scottish borders. The coal would be exported to European steelworks.

Both sites would produce coking coal which is processed into coke and used at steel works which use high carbon blast furnaces. Port Talbot and Scunthorpe steelworks use these methods and are the second and third biggest single source emitters of carbon in the UK.

It is possible to make steel without coal using electric arc furnaces and recycling as well as through direct reduction iron production. New methods to produce steel with hydrogen are being trialled.

Coal-use in electricity declined to its lowest ever level in 2021, thanks to grassroots and NGO campaigning for a total phase-out of coal by 2025 which has now been brought forward to 2024.

There are now only three power stations left open in the UK running occasionally.
