To document and report that the energy you consume in North America comes from renewable energy sources, you must buy Renewable Energy Certificates (RECs). In the US RECs are used both for compliance reporting as well as voluntary consumption, and comply with the Greenhouse Gas Protocol. Green Energy Solutions also offers Green-e eligible RECs across North America. Green-e is North America’s leading certification program for renewable energy.

How RECs work

Renewable Energy Certificates (RECs) are designed as a market-based instrument to provide an economic incentive for electricity generation from renewable energy sources. Each REC represents proof that 1 MWh of renewable energy has been produced and embodies the environmental benefits associated with that amount of generated renewable energy. REC registries electronically issue RECs based on renewable energy generators’ output. A REC, and its associated attributes and benefits, can be sold together or separately from the underlying physical electricity associated with the renewable energy generation. RECs are an effective and recognized way of reaching emission targets and improving sustainability.

RECs are traded. When a company buys RECs as documentation for the electricity delivered or consumed, those RECs are canceled in the registry. This single standardized instrument makes it easy to track ownership, verify claims, and ensure that RECs are only sold once and there is no double counting.

Global Equivalents: How They Work

Other parts of the world have similar products to the Renewable Energy Certificates (RECs): Guarantees of Origin (GOs) in Europe, Green Energy Certificates (GECs) in Japan, Large-Scale Generation Certificates (LGCs) in Australia, and International RECs (I-RECs) and Tradeable Instruments for Global Renewables (TIGRs) in much of the rest of the world.  In each case, the product represents the environmental benefits (but not the electricity) associated with one megawatt-hour of renewable energy generated. From wind and solar to hydro and biogas (think cows), RECs, GOs, GECs, I-RECs, LGCs and TIGRs  allow companies to support renewable energy no matter where they source their power. They also provide additional revenue which allows renewable energy projects to be cost competitive with traditional sources of energy.

The map below shows countries that are authorized to issue RECs and their global equivalents–meaning renewable energy projects in these countries generate certificates that can be bought and sold separately from the underlying electricity.

Due to grid-connection and market boundaries that extend beyond national borders, certificates are available for customers with load in almost every country across the globe.

RECs are a market-based instrument and an effective way to increase the market demand for renewable energy. Buying RECs demonstrates environmental leadership, sends a signal to the market that you prefer to consume renewable energy, and shows your commitment to changing energy behaviour. RECs also give power producers an extra income source, making it more appealing to build more renewable energy production.


RECs can be used for compliance reporting purposes under various state mandated renewable portfolio standards (RPS) protocols or voluntary Scope 2 reporting. Corporate stakeholders have increasing expectations about reporting the origin of the power consumed. They expect that companies report according to international standards including the CDP reporting and the Greenhouse Gas Protocol. The updated Greenhouse Gas Protocol Scope 2 Guidance features Guarantees of Origin, RECs and I-RECs as mainstream instruments for documenting and tracking electricity consumed from renewable sources.
