carbon-free
No fossil fuels
Carbon-free describes energy sources, processes, or products that don't release carbon dioxide into the atmosphere.
Nuclear and solar power are carbon-free; coal and natural gas are not.
The term appears frequently in climate policy discussions: The city committed to carbon-free electricity by 2030.
Sometimes used loosely to mean low-carbon rather than literally zero emissions.
