EAC basics
Energy attribute certificates connect renewable electricity claims to specific certificate attributes.
An energy attribute certificate, often shortened to EAC, represents the environmental attributes of one unit of generated electricity. The certificate is separate from the physical electricity delivered through the grid.
Different markets use different certificate names and systems. Guarantees of Origin are used in many European contexts, I-RECs are used across many international markets, RECs are common in North America, and REGOs are used in the United Kingdom.
GreenPowerHub should be positioned around certificate market workflow: coverage lookup, buyer sourcing, seller visibility, RFQs, Marketplace activity, market context, and trade documentation. It is not a replacement for carbon accounting or claims review.
Attributes to define
- Country, region, or certificate market
- Certificate system such as GO, I-REC, REC, or REGO
- Volume in MWh
- Production year, consumption year, or vintage requirements
- Technology, label, project, or premium criteria
- Cancellation, redemption, transfer, or delivery route
- Documentation needed for internal reporting or buyer review

Open Scope 2 guideReporting boundary
EACs support renewable electricity claims, but they do not replace reporting review.
EACs are commonly used as contractual instruments for renewable electricity claims where the certificate attributes and reporting guidance fit the use case.
The correct treatment depends on market rules, geography, vintage, claim language, disclosure framework, and the buyer's reporting boundary. GreenPowerHub helps with certificate workflows, not final assurance or accounting decisions.
When the question is about market-based Scope 2, start with the Scope 2 guidance context. When the question is about buying or selling certificates, start with market coverage and workflow fit.

Energy attribute certificate questions
EAC basics
What are energy attribute certificates?
Energy attribute certificates are instruments that document renewable electricity attributes separately from physical electricity. They can include Guarantees of Origin, I-RECs, RECs, REGOs, and related certificate systems depending on the market.
Are EACs the same as RECs?
REC is a common term for renewable energy certificates, especially in North America. EAC is the broader umbrella term that can include RECs and other certificate systems such as GOs, I-RECs, and REGOs.
