We are a carbon registry for real estate
The Building Emissions Reduction Standard (BERS) is Ontoly's certification framework for quantifying, certifying, and issuing carbon credits for building retrofits. These credits are called Building Emissions Reduction Units (BERUs) and are tracked from issuance to retirement on the Ontoly Registry.
