What is a Certified REC?
Certified RECs are certified by a third party to ensure the purchaser that the environmental attributes are indeed real and verifiable. Certified RECs must have an audit trial to prove their validity. GDF SUEZ Energy Resources markets certified RECs that are verified by the Center for Resource Solutions (CRS) (www.resource-solutions.org/index.php) and are sold under the name Green-e® name and logo. Costs vary according to source, market conditions, and location. Many companies may require that only certified RECs be purchased.
