January 5, 2018 - Britain will set a limit on carbon dioxide (CO2) emissions from power generators from Oct. 1, 2025, as a part of its plans to phase-out coal power generation, the government said on Friday.

Power plants will be limited to 450 grammes of CO2 for each kilowatt hour of electricity produced, ruling out coal-fired plants unless they are fitted with technolgy to capture and store emissions underground. 

The government first announced its 2025 coal phase-out plan in 2015, but Friday's announcement is the first detail on how this will be carried out.
