Green-e is run by the Center for Resource Solutions (CRS),and both sets standards for US renewable energy projects and verifies those projects. Green-e certified Renewable Energy Credits (RECs) have to be generated by power plants that were built after 1997 and cannot be used to also meet regulatory portfolio standards.

While RECs do not have to adhere to the same strict additionality standards as carbon offsets, CRS is currently working on developing new, stricter standards for RECs that are converted to carbon offsets.
