 Energy Attribute Certificates, or EACs, document the environmental attributes of electricity generation. One certificate commonly represents one megawatt-hour of renewable electricity, and companies use EACs to support renewable electricity sourcing and market-based Scope 2 reporting.

## EAC is the broad category for renewable electricity certificates.

Different markets use different certificate systems. Examples include Guarantees of Origin in Europe, RECs in North America, I-RECs in many international markets, and REGOs in the United Kingdom.

The certificate system, generation country, consumption or claim country, volume, production period, technology, and cancellation or redemption route all matter for a sourcing decision.

GreenPowerHub helps teams move from EAC terminology into practical market coverage, RFQ, marketplace, price, API, and documentation workflows.

## What to check next

- Use EAC as the umbrella term for certificate systems.
- Check which system applies before sourcing or making a claim.
- Match volume, vintage, technology, market, and documentation to the buyer need.
- Use a structured workflow when comparing offers across markets.
