2. Standards and Governing Documents

North America

  • Appendix B: Green-e® Energy Code of Conduct for Canada and the United States is one of the main governing documents of Green-e® Energy, and outlines requirements for consumer protection and environmental standards. Updated April 1, 2020 (UPDATED)
  • Appendix D: Green-e Renewable Energy Standard for Canada and the United States (formerly Green-e® Energy National Standard), v3.4. Covers renewable resource eligibility and product specifications. (View changes from v3.3, v3.2, v3.1, and v3.0.) (UPDATED)

    Reporting requirements for certification of long-term contracts that meet the requirements of Section II.H of the Green-e® Renewable Energy Standard for Canada and the United States:  To meet the requirements of Section II.H, the list of non-residential end-use purchasers of the contracted supply in the Green-e® Energy certified transaction must be reported to Green-e® staff according to the below deadlines. "Green-e® Eligibility Date" is defined as the date of Green-e® Energy eligibility per Section II.E.1–7.

    Green-e® Eligibility Date Deadline for Green-e® Reporting
    July 1, 2016–June 30, 2017 March 31, 2018

  • Appendix I: Green-e Glossary helps explain and define terms used in Green-e® governing documents.



  • Green-e™ Renewable Energy Standard for Singapore provides Green-e™ Energy's requirements for certified renewable electricity sales and consumption in Singapore.
  • Terms of Reference (Singapore) lays out the key issues that the Standard for Singapore addresses, including market need, sustainability, comparison to and compatibility with other existing relevant standards, implementation risk and how to address such risk.

4. Guidance Documents

  • Tracking Attestations. A review of the Tracking Attestation process, beginning with whether renewable energy or renewable energy certificates (RECs) generated from a specific facility meet certain criteria in the Green-e® Renewable Energy Standard for Canada and the United States, and whether the facility has completed the process to be listed on the “Approved Tracking Attestations” page by CRS.
  • Green-e® Residual Mix Emissions Rate Tables. CRS publishes annual "Residual Mix" emissions rates, which are CO2 emissions rates that should be applied to all electricity use that is not associated with a Green-e® Energy certified product or for which a more specific set of emissions data is not available. These rates are compatible with the World Resources Institute's (WRI's) guidance.
  • Green-e Energy Summary of WRI Scope 2 Guidance summarizes the major takeaways from WRI's Scope 2 accounting guidelines as well as required and optional reporting under this guidance.
  • Standardized PPA Language Providing for Green-e® Certification. Buyers who use power purchase agreements (PPAs) as a procurement method may want to plan for future Green-e® certification of the generation and environmental attributes, including renewable energy certificates (RECs), within the text of the PPA contract. CRS recommends including this PPA contract language to lay the groundwork for Green-e® certification to come.

5. Attestation Forms for Facilities Within a Tracking System

These forms are used to substantiate the chain of custody of all renewable MWh (renewable electricity or standalone RECs) used in Green-e® Energy certified sales. Renewable energy generators must be registered in an approved tracking system (see "Approved Tracking Systems" below).

6. Attestation Forms for Facilities Not in a Tracking System

Attestations for sales of RECs and renewable electricity from facilities not registered in an Electronic Tracking System. These do not grant any specific Green-e® Energy eligibility status; the ultimate determination of eligibility lies with Green-e® Energy staff during the annual verification audit. Facilities not in a Tracking System may only use these forms.


To Know

  • Approved Tracking Systems. Renewable energy generators in North America must be registered in one or more of the following approved tracking systems: ERCOT, MIRECS, MRETS, NAR, NCRETS, NEPOOL GIS, NYGATS, PJM GATS, or WREGIS. Approved international tracking systems include I-REC (Chile) and TIGRS (Singapore).
