Granular certificate infrastructure

Measurement & verification that proves actual emission reductions

End-to-end auditability that links every EAC to a real-world project and certifies the associated time and locational carbon savings.

One-click data integrations

Use the data that you already collect to start tracking your building and energy assets today. Just connect and go; it's really that easy.

Granular certificate tracking

An EAC is the atomic unit of decarbonization, representing one gram of carbon emission reductions and its associated energy value. Each EAC tracked by WattCarbon receives a unique serial number in WEATS, which prevents double counting and allows impact claims to be transferred between third parties.

Open standards, verified impact

WattCarbon is a founding member of the OpenEAC Alliance. The Alliance is an industry group of measurement & verification professionals that review and approve methodologies used to calculate emissions savings.
