Double Claims and Generator Claims (Section III.E)
Regarding double claims in materials published by a generator or other supplier providing renewable MWh to sellers of Green-e Energy Certified products, counting electricity from which RECs have been sold as ‘zero emissions" when reporting electricity sales constitutes a double claim on those RECs. For example, if a utility sells RECs to another party and also counts the resulting null power as renewable when reporting electricity sales, this is a double claim resulting in RECs that are ineligible for use in a Green-e Energy Certified product. Likewise, there is a double claim if null power is disclosed as zero emissions for the purpose of informing electricity end users of the overall emissions from delivered electricity. This includes annual reports that display emissions from electricity supplied to end users. It is necessary to assign null power the emissions characteristics of system power for the purposes of reporting emissions linked to electricity sales.
Accurate statements by generators or generation owners about renewables in their generation portfolio are acceptable, but to ensure against double claims, statements about generation should be closely accompanied by the resource mix of actual sales. Such disclosure should account for RECs not being included with any null power delivered, and RECs and their zero-emissions attributes should be factored out of resource and emissions calculations. Such disclosure helps avoid misleading customers about the content of the electricity they are actually receiving.
Such an interpretation of the requirements of the Green-e Energy National Standard and Code of Conduct are directly in line with the FTC Green Guides
, which state on page 223, "If a marketer generates renewable electricity but sells renewable energy certificates for all of that electricity, it would be deceptive for the marketer to represent, directly or by implication, that it uses renewable energy."
We strongly encourage marketers to investigate the statements being made by generators about the electricity they are selling before contracting for the sale of RECs. While these generators have to attest that they have not made claims on the RECs, a determination by Green-e Energy staff that the RECs are being claimed due to statements made by generators and / or null power buyers, users or sellers will render such RECs ineligible. To avoid this, it is in your best interest to proactively research counterparties" statements that may affect eligibility and educating your suppliers about the impact of marketing statements that create unintentional claim on the RECs.
We encourage everyone to read the following documents on green marketing claims and the evaluation of statements for double claims, put together by Center for Resource Solutions, all of which are available on our REC Claims and Ownership

Federal Policy and the Green-e Energy National Standard
The Green-e Energy National Standard is a dynamic document, which strives to set rigorous environmental and consumer protection standards for the voluntary renewable energy market to ensure high quality products and processes. The Green-e Energy National Standard responds to changes in the marketplace for renewables, as is evident from Appendix A on State-Specific Requirements and Restrictions. In the event of policies on a national cap-and-trade program or a national renewable energy standard (RES), the Green-e Energy National Standard would necessarily be updated to reflect resulting changes in the renewable energy market.
In certain proposed national legislation, renewable electricity generation could be granted not only a REC, but potentially also a carbon allowance and/or a "Federal REC" (which would be issued exclusively by the federal government and used for compliance with a national RES). While Green-e Energy cannot state precisely how the National Standard would have to change to adapt to these new federal laws, it is worth noting previous treatment of similar state or regional laws by the National Standard.
The Green-e Energy National Standard requires that a REC / renewable MWh is "fully aggregated to the extent possible under law" and contains all environmental attributes that are linked to its generation. In the case of multiple kinds of RECs or attributes being created with each MWh of renewable electricity generation, all types of RECs and attributes associated with generation of a particular MWh must be retired for a voluntary retail purchase in order for the purchaser to have full and exclusive claim to that renewable MWh. For example, a 2008 law passed in Texas issued certain non-wind renewable MWh both a REC and a Compliance Premium, either of which could be used for RPS compliance; in response, Green-e Energy policy adapted by requiring an otherwise Green-e eligible Texas non-wind REC to be bundled with an associated Compliance Premium to remain eligible for Green-e Energy certification. This is analogous to what could be required if each renewable MWh generates both a REC as is currently known as well as a Federal REC.
In the case of a cap-and-trade program, Green-e Energy already has rules about treatment of renewable MWh generated and sold under the Regional Greenhouse Gas Initiative (RGGI). These rules require that RGGI RECs sold in RGGI states (except Delaware) cause a commensurate amount of CO2 emissions allowances to be retired along with the REC in a voluntary sale, so that the purchaser has the full claim to all available environmental benefits of the renewable electricity generation. This is similar to what could be required under a national cap-and-trade program.
If and when laws affecting the voluntary renewable energy market are passed, Green-e Energy will identify what, if any, types of changes are necessary to maintain the integrity and entirety of voluntary market claims on renewable MWh and will act in accordance with Section VI of the National Standard.
Green-e Energy Code of Conduct
Download the Green-e Energy Code of Conduct
Green-e Energy Code of Conduct is one of the main governing documents of
Green-e Energy. It ensures that participating
marketers abide by the consumer protection and environmental standards
established by the Center
for Resource Solutions. Signatories
of the Green-e Energy Code of Conduct pledge to abide by the standard and cooperate
with the Green-e Governance Board, to ensure that these standards
are effective in providing customers information about environmentally
superior services in the renewable energy market.
The Green-e Energy Code of Conduct outlines the responsibilities
of a company offering a Green-e Energy certified product to disclose product
information to all customers prior to their purchase and in the case
that their purchase changes during the term of their purchase agreement. This
document also provides language
for describing Green-e Energy, language for describing a company's
relationship with the Center for Resource Solutions and Green-e Energy, and logo use (see below). Additionally,
the Green-e Energy Code of Conduct outlines the process for CRS review
of marketing materials including the twice-annual marketing compliance
The Green-e Energy Code of Conduct underwent a major update in the July 24, 2015 version. Participants are required to comply with this version beginning July 24, 2016. The previous version of the Code of Conduct was revised November 6, 2013, and is available here.
Market Notice Regarding Use of the Term "Green-e Eligible"
Center for Resource Solutions (CRS) has been made aware of confusion in the marketplace regarding Section IV.A3 of the Green-e Energy Code of Conduct, which prohibits Participants (entities with a contract with CRS to sell a Green-e Energy Certified product) from using the term "Green-e Eligible"—for example, to describe products that may meet Green-e Energy requirements but are not certified. CRS is posting this notice to inform the market that the intent of this prohibition is to prevent non-certified products from being misrepresented as certified to end-users (who may not differentiate between the terms "certifiable" or "eligible," and "certified"). The term "Green-e Eligible" is permitted in contracting for wholesale transactions, where the buyer is not the end-user of the renewable electricity or renewable energy certificate (REC).
