RECs and Global Equivalents

The international currency of green power

It started with a few small companies passionate about moving the needle. The renewable energy industry was in its infancy and renewable energy certificates (RECs) were becoming the new currency of green power. Cut to 15 years later, 3Degrees supplies RECs, Guarantees of Origin (GOs), TIGRs, I-RECs, and other national REC products like Large-scale Generation Certificates (LGCs) and Green Energy Certificates (GECs) to some of the biggest names in the business, helping Global 1000 companies, universities, utilities and other organizations meet their sustainability goals and reduce their electricity carbon footprint.

The best part? We work with each client to build a product sourced from renewable energy projects that matter to them — balancing cost, technology and geography to deliver a product that meets their needs. In fact, we’ve purchased and committed to over 120 million megawatt hours of renewable energy across the globe. That’s a lot of power.

What makes us different:

Proven leadership: Over the past 15 years, 3Degrees has focused on building a healthy market for renewable energy worldwide — working with developers to get new projects built while playing a lead role in a number of industry associations.

One stop shop: Having done business in over 60 countries, we’re well equipped to help our clients source high-quality, global renewable energy products — including RECs, GOs, GECs, I-RECs, LGCs and TIGRs — to meet their needs across the globe.

Customized solutions:  Our clients want renewable energy solutions that balance cost, technology and geography. And we provide exactly that with our large, diverse portfolio of international renewable energy options that include RECs, GOs, GECs, I-RECs, LGCs and TIGRs.  We offer a range of projects, an array of payment options, flexible delivery, as well as lightning fast contracting.

Reliability and integrity:  Companies who purchase renewable energy from 3Degrees value dependability and specificity. Unlike some in the industry, we provide every client with the full detail on the RECs, GOs, GECs, I-RECs, LGCs and TIGRs they purchase — including technology, project site, and vintage. In addition, all of our North American RECs are third-party certified and exceed Green-e requirements.


Renewable energy certificates (RECs) enable businesses, organizations and individuals to reduce the environmental impact of their energy use and support renewable energy projects in North America. Other parts of the world have similar products: 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.
