What Are EACs

Energy Attribute Certificates (EACs) are tracking instruments that represent 1 MWh of electricity generated from a renewable source. When a generator produces renewable power, an EAC is issued to document its origin. Each certificate includes details such as the generation date, location, and technology type.

Why Companies Buy EACs

EACs are used to demonstrate the use of renewable electricity and support environmental reporting. They allow companies to reduce Scope 2 emissions and make credible environmental claims.

EACs Generation Sources

EACs can be issued for electricity generated from various renewable technologies and are available on our Marketplace:

Solar

Wind

Hydropower (including small hydro)

Biomass

Geothermal

Market Coverage

EACs are used globally, but their systems are country-specific. Each certificate must be issued and purchased in the same country or market where the electricity is consumed. While EACs support international reporting, their use is tied to local rules and geographic boundaries. We provide access to all types of EACs or you can request specific certificates not currently listed.

Retirement & Claiming Process

To make a renewable energy claim, an EAC must be retired. Retirement means the certificate is taken out of circulation and cannot be resold or reused. EACs are typically retired by the buyer or an authorized representative. This step ensures that the environmental benefit is counted only once and is linked to a specific reporting period or purpose. When purchasing through our Marketplace, redemption certificates can be downloaded directly from the platform.

Voluntary Schemes

EACs we provide are aligned with the requirements of all major voluntary schemes.

Ecolabels

EACs can carry ecolabels that reflect additional environmental or quality standards beyond basic renewable generation. These labels help buyers demonstrate a stronger commitment to sustainability and responsible sourcing.
