Built for building owners, retrofit consultants, and engineering firms. Track your carbon credits, portfolio value, and holdings — all issued from real metered utility data, not modeled estimates.
Securely upload building performance data and documentation. Ontoly standardizes, validates, and prepares your inputs for methodology-based emissions calculations — no carbon expertise required on your end.
Our engines run deterministic, reproducible calculations — GHG quantification, financial-additionality analysis, and regulatory screening — against your metered pre- and post-retrofit data. Verified Building Emissions Reduction Units (BERUs) are issued directly to your account.
Issued BERUs go straight to our buyer network — enterprise credit buyers, brokers, and bank trading desks — for transparent purchase, transfer, and retirement. You get paid; we handle everything else.
A Building Emissions Reduction Unit is a carbon credit representing one tonne of CO2e reduced through a certified building retrofit — issued, tracked, and retired on the Ontoly Registry.
Every BERU is quantified from measured utility data, not models or estimates, and traces to a specific building and retrofit — no mega-project aggregation.
Building owners, managers, retrofit engineering firms, and consultants with eligible retrofit projects under the BERS Program. Check eligibility on the program page.
Voluntary offsetting, green building certification offsets (LEED v5, Zero Carbon Standard), and — subject to jurisdictional approval — compliance under emerging Building Performance Standards.
