What We Do
What We Do
For over 30 years, the Green-e® program has been the trusted global leader in clean energy verification and certification
The Green-e® certification program accelerates the transition to a renewable, resilient energy system by making it easy and credible for individuals and businesses to find and purchase renewable energy and carbon-reduction products with confidence.
Our Mission
Center for Resource Solutions’ Green-e® certification program is the trusted global leader in clean energy certification. We make it easy for businesses and individuals to purchase verified renewable energy products with confidence, and for consumers to choose sustainable products and services. We advocate for the advancement of clean energy policy, markets, and technology, and believe in their economic and environmental benefits. By working together, we can power a renewable future.
How We Make a Difference
- A certification you can trust
We verify the entire chain of custody for renewable energy, carbon offsets, and fuel-based products—from generation to final retirement—so every claim is backed by documented, third-party review.- We ensure the energy attributes are from recent facilities, accurately marketed, and owned solely by the purchaser
- We ensure consumers and businesses can make accurate claims about their renewable energy and offset use
- We publish annual verification reports on the previous year’s supply, sales, and resource and product types
- Market leadership and standard setting
Since 1997, the Green-e® program has been the leading renewable energy certification program in North America, and is available in select Southeast Asian and South American countries.- We collaborate with stakeholders, including regulators, industry, and NGOs, to develop robust standards that drive measurable environmental benefit
- Our standards help buyers make credible sustainability claims, and help sellers deliver high-quality products
- We support the transition to new renewable technologies and fuel types—such as renewable hydrogen and biogas—ensuring high-quality accounting across evolving markets

A wide range of stakeholders are served by Green-e® certification:- Businesses that want to power operations with verified renewable energy, procure credible carbon offsets, or certify their renewable energy marketing claims
- Consumers choosing a certified renewable energy product, carbon offset, or sustainable fuel
- Marketplaces and product manufacturers embedding certified energy or fuels into their supply chains
- Policymakers and procurement leaders seeking credible frameworks for renewable and low-carbon procurement
Why It Matters
The world faces a growing urgency to shift from fossil-based to renewable energy generation. Yet simply buying “green” doesn’t automatically guarantee meaningful impact—unless the supply is credible, transparent, and is not double-counted. That’s where the Green-e® difference lies: we verify and certify the highest quality sustainable solutions for individuals and businesses looking to reduce their impact.
By steering demand toward newer generation, cleaner fuels, and verified low-carbon pathways, we help drive investment, innovation, and scalability across the energy transition.
Let’s work together to power a renewable future.
