CnerG Now Offers Green-e® Energy Certified US RECs

CnerG can now provide Green-e® Energy certified US RECs directly to corporate buyers. Our US REC product is listed in the official Green-e directory of certified renewable energy products, marking an important step in the growth of our North American offering. For clients, this means certified US REC sourcing, retirement and documentation can now be managed directly with CnerG.

Green-e is already familiar to many renewable energy buyers in North America. It regularly appears in corporate tenders, procurement policies and conversations about REC quality. Still, the label can be misunderstood, particularly when buyers are trying to distinguish between a Green-e Energy certified product, a CRS Listed generating facility and a standard US REC. So, what does certification actually cover?

What Is Green-e Energy Certification?

Green-e Energy is a third-party certification program administered by the nonprofit Center for Resource Solutions, or CRS. For nearly three decades, it has provided independent oversight for voluntary renewable electricity transactions. Its North American standard sets environmental and consumer-protection requirements for certified renewable electricity and REC products in the United States and Canada.

A REC represents the renewable attributes associated with one megawatt-hour of electricity generated from an eligible renewable source. The REC itself does not contain electricity. Once it is paired with a company’s electricity consumption and retired on that company’s behalf, it supports the company’s claim to the renewable attributes represented by the certificate.

Green-e Energy does not replace the REC registries that issue, track and retire certificates. Instead, it adds an independent certification layer over the renewable energy product and the way it is sourced, sold, disclosed and verified. That broader role is why Green-e is often treated as a leading voluntary certification for US and Canadian REC procurement.

Although Green-e Energy certification is now available in several markets outside North America, the requirements vary by market. CnerG’s newly certified offering is its US REC product, which follows the Green-e Renewable Energy Standard for Canada and the United States. The certification applies specifically to this product and does not automatically extend to every product or market offered by CnerG.

What Does Green-e Energy Certification Require?

Green-e Energy certification looks beyond the existence of a REC in a tracking system. The applicable supply, the sale to the buyer, the retirement process, customer disclosures and marketing claims all form part of the certified product. This gives buyers a common set of requirements across transactions that may otherwise involve different registries, regions and renewable technologies.

Renewable source and facility age. Under the North American standard, certified supply must come from approved renewable resources. These include certain wind, solar, geothermal, biomass and low-impact hydropower facilities. In general, the generating facility must have been built or repowered within the previous 15 years, which creates a rolling definition of newer renewable supply.

Voluntary supply. Renewable energy used in a Green-e Energy certified voluntary product cannot also be counted toward a government renewable energy mandate or another entity’s renewable electricity requirement. This separates voluntary corporate demand from renewable generation already being used to meet a regulated target. State- and province-specific rules may also apply, depending on where the generation originates.

Exclusive ownership and retirement. A certified REC must be sold only once and retired for the purchaser so that another organization cannot claim the same renewable attributes. Participants must also take reasonable steps to identify possible double claims elsewhere in the supply chain. Approved electronic tracking systems provide the registry records used to document ownership, transfer and retirement.

Clear information for the buyer. Sellers of certified products have formal disclosure obligations. Buyers receive information about the product’s quantity, renewable resource type and geographic source, along with the applicable price, terms and conditions. Green-e also requires prospective and historical Product Content Labels so that clients can compare what was offered with the supply ultimately delivered.

Accurate marketing claims. Green-e reviews how certified products are described and sold. For REC products, sellers must make clear that the buyer is purchasing certificates rather than physical electricity from the REC provider. Marketing must also avoid overstating environmental outcomes or suggesting that a non-certified product, project or generating facility carries Green-e certification.

Annual independent review. Green-e Energy participants complete a yearly audit of certified purchases and sales. A third-party auditor reviews the transaction data and supporting records, while CRS carries out the full verification and makes the certification determination. Green-e staff also conduct a separate annual review of product labels, terms, website content and other customer-facing materials.

Together, these requirements address several questions that sustainability and procurement teams often need to answer. Where did the certificates come from? Were they sold and claimed only once? Were they retired for the right customer and reporting period? Did the buyer receive an accurate description of what was purchased?

Is a Renewable Energy Project Itself Green-e Certified?

This is one of the most important distinctions in the program. Green-e Energy certifies renewable energy products and transactions offered by participating providers. A wind farm, solar project or other generating facility should not be described as Green-e Energy certified simply because its output could be used within a certified product.

Some generating facilities are identified as CRS Listed. This means CRS has accepted a Tracking Attestation for the facility after reviewing selected information, including matters connected to renewable attribute ownership and possible double claims. Supply from a CRS Listed facility can make parts of the later verification process more straightforward for a Green-e Energy participant.

CRS Listed status is not the same as Green-e Energy certification. CRS has not yet reviewed the full chain of custody, confirmed the final retirement or verified the sale to an end buyer simply by accepting the facility’s attestation. Those checks take place within the broader certification and annual verification process for the finished product.

For the same reason, CRS no longer permits the expressions “Green-e eligible” or “Green-e certifiable.” These terms can suggest that certification is already guaranteed when other requirements still need to be met. The correct description is “CRS Listed” for the facility and “Green-e Energy certified” for the certified product supplied to the buyer.

How Does the Certification Process Work in Practice?

When a buyer requests Green-e Energy certified US RECs, CnerG identifies supply that can be used within our certified product and checks it against the applicable transaction requirements. The RECs are then sold and retired according to the agreed volume, reporting period and buyer details. The client also receives the disclosures and documentation required for the certified product.

The product is already certified under CnerG’s active Green-e Energy agreement, so a buyer does not ordinarily need to wait until the following year before purchasing it as a certified product. However, the completed transactions remain subject to the program’s annual verification cycle. This combination allows certified products to be sold during the reporting year while maintaining retrospective scrutiny of what was procured, sold and delivered.

After the reporting year closes, participants report their certified sales and provide the records required for verification. A third-party auditor reviews materials such as purchase and sales data, generating-facility information, registry records, contracts, invoices and Product Content Labels. The auditor submits its findings to CRS, which reviews the complete submission and performs the program’s verification.

The audited submission is typically due around the beginning of June in the following year, although the exact annual schedule is set by Green-e. This is the timing discussed when people refer to a certified sale being reviewed the next year. The later audit does not mean that Green-e certification only appears after June; it is the accountability process that supports certified sales already made under the program.

There is also a separate Marketing Compliance Review each year. Green-e staff examine the language, product information, terms and other materials used to market certified products to customers. This matters because Green-e Energy is designed as a consumer-protection program as well as an environmental standard, so transparent communication is part of certification rather than an optional addition.

Why Do Corporate REC Buyers Ask for Green-e?

For many buyers, the value of Green-e is the presence of an established third party between the seller’s claims and the company’s final renewable electricity claim. Corporate teams may be sourcing across several US regions, registries and technologies, while internal stakeholders still expect one recognizable quality benchmark. Certification gives those teams a defined standard for evaluating the finished REC product and its delivery.

Green-e is also recognized across major sustainability programs and reporting frameworks, including LEED, CDP, the GHG Protocol and RE100. This has made it familiar to sustainability teams, procurement departments and consultants. Its role varies by framework and company circumstances, so certification should not be treated as a universal reporting requirement, but it is often included in internal sourcing policies or preferred procurement criteria.

In CnerG’s experience, many corporate tenders ask suppliers to quote both Green-e Energy certified and non-certified US REC options. The buyer can then compare the premium associated with certification against its reporting needs, internal policy and risk preferences. Some companies request Green-e for all US procurement, while others reserve it for particular business units, customer commitments or public claims.

Demand is not limited to companies headquartered in the United States. A multinational business based in Asia or Europe may still request Green-e Energy certified RECs for its US operations because the certification applies to the relevant North American procurement. This makes Green-e part of a global renewable electricity strategy even though the underlying certificates and electricity consumption are tied to the US or Canadian market.

Are Non-Certified US RECs Still Valid?

Green-e certification should not be interpreted to mean that every non-certified US REC is invalid or unsuitable. Non-certified RECs can still be issued through recognized registries, transferred through documented accounts and retired for a corporate buyer. Depending on the buyer’s reporting framework and quality criteria, they may support a valid market-based Scope 2 claim.

The difference is the additional layer of standards, disclosures, marketing rules and independent oversight attached to a Green-e Energy certified product. Some buyers value that layer because it fits an internal policy or provides added confidence around a public claim. Others may decide that registry documentation and their own procurement controls are sufficient for a particular transaction.

Certification is also only one part of a sourcing decision. Buyers may still need to consider geography, grid-market boundaries, technology, vintage, facility age, price, contractual terms and the connection between the procurement and their broader renewable electricity strategy. A Green-e label answers important quality and consumer-protection questions, but it does not remove the need to select supply that fits the company’s actual operations and goals.

This is why CnerG can provide pricing and guidance for both Green-e Energy certified and non-certified US REC volumes. The right option depends on what the company needs to report, the claims it plans to make and the procurement requirements it has adopted. Buyers can compare the available supply and make that decision with a clear view of what certification adds.
