Attest

Attest brings real-time evidence to carbon removal markets.

Attest complements traditional registry and audit processes with continuous, registry-attested evidence: Real-time temperature sensors, weight tickets, and more.

WHY ATTEST

Carbon buyers want to receive exactly what they ordered, on spec and on time. Today, they have no way of knowing before delivery if projects are on track. What is missing is a reliable view of credit production before issuance.

Attest changes that.

What is attest

A registry-integrated evidence infrastructure for tracking carbon removal progress before formal audits and certification.

Attest transforms how buyers and capital markets, from financiers to insurers, engage with carbon removal production. We partner with registries with robust digital MRV infrastructure to provide registry-attested, time series evidence that complements traditional audit samples.

Built for Farmers, Registries and Verifiers.

Built for Users
Climate and agrifood are complex and rapidly evolving, so we aim to stay fresh and ahead of the curve. We are constantly learning about and testing the latest in (i) technology; (ii) data analytics; and (iii) methodologies - and anything else that might come up.

The more we can reduce MRV costs and improve the quantity and verifiability of carbon capture and storage, the higher our margins—and the more farmers can benefit from our model, sustainably and at scale.
