How coal co-firing is harming the energy transition

Written by Admin | Apr 3, 2025 11:00:00 PM

Coal co-firing prolongs the damage coal does to our planet. It also diverts finance and focus away from greater renewable electricity generation and could lock coal into electricity grids for years to come. 

Co-firing is the burning of two different fuels together at the same time to generate power. It often involves the burning of a renewable fuel, like biomass wood pellets, with a fossil fuel such as coal. In the fight against climate change, all emissions count and that means there’s no role for coal.

RE100’s updated technical criteria no longer allow members to claim renewable electricity use from co-firing that involves coal. RE100 updates its technical criteria every two years to ensure the campaign, and its members, keep accelerating the global transition to 100% renewable electricity. By ending the use of co-firing with coal by RE100 members, markets will shift towards more impactful renewables faster, speeding up grid decarbonisation.  You can learn more in our Q&A blog.
