CRS Green-e Renewable Energy Certificates (RECs) represent the environmental benefits of 1 megawatt-hour (MWh) of renewable energy generated and delivered to the grid. By purchasing Green-e RECs, businesses support the generation of renewable energy, even if their electricity comes from non-renewable sources. Green-e is the leading certification program for renewable energy, ensuring that the RECs meet environmental and consumer protection standards.

Ontario Clean Energy Credits (CECs) are similar to RECs but are specific to the province of Ontario. These credits allow businesses to support the generation of clean energy within Ontario and work toward achieving the province’s environmental goals. By purchasing Ontario CECs, companies can claim the environmental attributes of renewable energy produced in the region.
