Why choose Puro.earth CORCs?

True Carbon Removal

Each certificate represents net-negative emissions — not avoided or reduced, but permanently removed CO2, quantified and verified to the highest standards.

Durability You Can Trust

Only methods that guarantee durable storage of carbon for at least 100 to 1,000+ years are eligible, from biochar to geological sequestration.

Transparency and Assurance

Every issued CORC is tracked in the public Puro Registry, ensuring complete transparency and preventing double counting.


Backed by Nasdaq

As a significant investor in Puro.earth, our partnership with Nasdaq fortifies our position in propelling the global scale-up of carbon removal.

Impact

Join leading companies like Microsoft, Shopify, and Zurich Insurance Group that trust Puro.earth to underpin their net zero journeys.

How the Registry works for Carbon Credit Buyers

Discover Suppliers


Explore a global network of rigorously vetted carbon removal suppliers, each meeting the robust Puro Standard for engineered carbon removal.

Obtain CORCs with Confidence 

CORCs are issued only after independent, third-party verification of carbon removal activities. Each CORC can be traced from issuance to retirement using our transparent registry.

Align with International Best Practices

Puro.earth is endorsed by global benchmarks such as the ICROA Code of Best Practice, making your carbon removal purchases recognized and credible for stakeholder reporting.

Flexibility for Corporate Buyers

CORCs can be acquired directly from suppliers, via trusted resellers, or through your preferred procurement channel. Puro.earth does not operate as a marketplace — you manage the relationships and procurement routes best aligned with your sustainability strategy.
