What EnergyTag does
EnergyTag is an independent UK non-profit standards body (EnergyTag Ltd, registered in London, 1-10 employees, founded circa 2020) that develops and promulgates the world's only voluntary open standard for issuing and verifying hourly Energy Attribute Certificates — branded as Granular Certificates (GC). The offering is structured as a three-part open-source standard stack: the Granular Certificate Scheme Standard (V2, March 2024), the GC Registry API Specification (V2, March 2024, co-developed with Future Energy Associates), and the Granular Certificate Matching Standard (V1, March 2024), supported by a formal GC Issuer Accreditation Process launched June 2026. EnergyTag's framework is built on three pillars — hourly matching, deliverability, and incrementality — and has been adopted as the methodological basis for the US 45V Clean Hydrogen Production Tax Credit final rule, elements of the EU CBAM electricity rules, components of the GHG Protocol Scope 2 update, and state-level hourly matching proposals in California, Colorado, Minnesota, and Illinois.
The organization's go-to-market is community-led and policy-driven rather than commercial: EnergyTag engages regulators through written comments and oral testimony (US Treasury, CARB, California Energy Commission, Colorado Senate, Illinois House, Minnesota PUC, EU Commission), coordinates coalitions of 25+ climate NGOs on corporate standard-setting (notably a June 2026 joint letter to SBTi), publishes country readiness reports with regional partners (e.g., Korea/KoSIF, APAC Factbook), runs a flagship campaign (Scope True) supporting GHGP Scope 2 reform, and accredits EAC registries (Flexidao, Granular Energy, Energinet DataHub) to issue EnergyTag-Compliant certificates that propagate the standard through corporate energy buyers (Google, ENGIE, KEPCO, Digital Realty, Einstein Bros. Bagels).
Revenue mechanics reflect the non-profit structure and consist of three streams: (1) donor/member contributions via a 'Get Involved' sign-up (the only disclosed funding event is a $144,861 grant from Subak in March 2022); (2) GC Issuer Accreditation fees and trademark licensing for registries achieving 'EnergyTag Compliant' or 'EnergyTag Accredited' status; and (3) advisory, research, and policy consulting engagements. No public pricing is disclosed. EnergyTag does not sell software; it sells standards adoption, accreditation, and policy influence. Its headcount of 1-10 and lack of disclosed revenue indicate a small organization whose strategic significance derives from regulatory codification, coalition leadership, and brand recognition (cited by WEF, IEA, IRENA, FT, BloombergNEF, S&P Global, US Senate EPW Committee, Princeton, MIT) rather than from commercial scale.

- Non-profit grants, donations, and member support: EnergyTag is an independent non-profit that supports itself through a 'Get Involved' sign-up and donor/member engagement model. Recurring contribution-style support rather than product sales.
- GC Issuer Accreditation fees and protocol licensing: Accreditation program through which EAC registries (e.g., Flexidao, Granular Energy, Energinet DataHub) become 'EnergyTag Compliant' or 'EnergyTag Accredited' and use the EnergyTag trademark, with public accreditation process documents and per-issuer protocols published.
- Advisory, research, and policy consulting engagements: Producing commissioned and partner-published research, country readiness reports, call-for-evidence responses, and policy briefs (e.g., Korea and China RTC clean power reports in partnership with KoSIF; APAC Factbook; EU PPA barriers response).

EnergyTag product offering
Product offeringCore offering
EnergyTag develops and publishes open-source standards for issuing and using hourly time-stamped Energy Attribute Certificates (Granular Certificates or GCs), which match electricity generation to consumption on the same grid and in the same hour. Its offering centers on the GC Scheme Standard, GC Registry API Specification, GC Matching Standard, and the formal GC Issuer Accreditation Programme that governs who can issue EnergyTag-Compliant certificates.
Product overview
EnergyTag operates as an independent non-profit standards body delivering a portfolio of open-source standards and tools that together form the Granular Certificate (GC) scheme. The offering is structured as a core standard supported by complementary technical and governance modules: the Granular Certificate Scheme Standard is the core product establishing hourly (24/7) clean power tracking methodology; the GC Registry API Specification provides the technical interoperability layer that lets compliant registries exchange hourly GC data; the Granular Certificate Matching Standard defines the rules for matching hourly generation and consumption claims; and the GC Issuer Accreditation Process governs who is authorized to issue GCs under the scheme. Together, these products enable hourly clean electricity tracking, claim-grade verification, and interoperability with EAC (Energy Attribute Certificate) registries worldwide.
