The Platform

Ontoly provides a secure platform that transforms verified building performance into credible, market-ready carbon assets. We manage the full carbon credit cycle — from data ingestion and emissions calculations to asset issuance, transfer, and retirement — enabling building owners, financial institutions, and carbon buyers to participate in climate markets with confidence.

At the core of Ontoly is a commitment to integrity and transparency. Our system supports methodology-based emissions reduction calculations, maintains clear chains of custody, and ensures every carbon unit is fully traceable from origin to retirement.

This infrastructure approach aligns incentives across building owners, capital providers, and buyers — while reducing the operational burden typically associated with carbon markets.

‍Why We Built the BERS Program
‍
Ontoly was founded in 2024 by Ashley Sarauer after years of working in both voluntary and compliance carbon markets — including drafting Verra's application to the Integrity Council for the Voluntary Carbon Market. That experience revealed a stark imbalance: despite buildings representing 26% of global emissions, almost no carbon finance was reaching building owners. We built Ontoly to change that.

The existing system wasn't built for buildings. Projects faced heavy administrative burdens, relied on modeled estimates rather than real data, and grouped thousands of buildings into single mega-projects that lost critical detail. Carbon finance was flowing, but not to where it was needed most.
‍
The BERS Program's credibility is grounded in the Founder's direct experience drafting carbon market regulations and submissions in the voluntary carbon market. All governance documents and processes are publicly available, and our submission for acceptance under the ICVCM Core Carbon Principles Assessment Framework can be reviewed on the Ontoly BERS Program page.

Making Climate Capital Work for Buildings

70% of today's buildings will still be standing in 2050. Decarbonizing the existing building stock — through high-quality energy efficiency upgrades and fuel switching — is one of the most impactful climate interventions available. Ontoly exists to make that happen faster.

Through the Ontoly Registry and Ontoly Portal, participants upload data, manage documentation, issue Building Emissions Reduction Units (BERUs), and transact directly with buyers in a transparent, auditable environment. We support both residential and commercial building portfolios, from individual assets to large aggregated programs.
