World's Most Seamless
Carbon Marketplace

One carbon credit represents one tonne of CO₂ equivalent reduced, avoided, or removed from the atmosphere by a verified project. Credits are issued by a registry only after the reduction has occurred and been independently confirmed, then retired against a buyer to prevent resale.

Verified credits carry certification under a recognized standard such as Verra, the Gold Standard, or the American Carbon Registry, plus a unique serial number in a public registry. Our buyer’s checklist sets out the five questions worth asking before any purchase.

A carbon credit represents one tonne of CO₂ reduced or removed and applies across your footprint. An I-REC (EAC) represents one megawatt-hour of renewable electricity and applies specifically to Scope 2 emissions management. Many organizations use both for different parts of the same inventory.

It depends on where your electricity is consumed. RECs apply in North America, Guarantees of Origin in Europe, and I-RECs across much of Asia, Africa, and Latin America. Our comparison of I-RECs, RECs, and GOs covers region, use case, pricing, and ESG treatment.

Under the GHG Protocol’s market-based method, retired certificates allow you to claim the renewable attribute of electricity you consumed. Each megawatt-hour retired reduces reported Scope 2 emissions. Our guide to the ESG to carbon credit journey walks through the full sequence.

Listings tie to recognized carbon standards, including Verra, Gold Standard, and CCB, with CORSIA and Article 6 eligibility flagged where applicable. Reporting aligns with CDP, the GHG Protocol, GRI, CSRD, and RE100. Full detail sits in our methodology.

The main factors that drive carbon credit pricing are project type, geography, vintage, permanence, and certification level. Nature-based removal typically costs more than avoidance credits, and technology-based removal costs more than both. Live pricing by market is available through Hestiya Intelligence and on our country market pages.

Yes, and credibility depends more on documentation than on volume. Measuring your footprint, reducing internally where possible, and disclosing which projects you funded matters more than the size of the purchase. Our guide for SMEs building climate credibility covers the approach.

Rating agencies weight materiality differently, use different data sources, and disagree on how to treat missing disclosure. The result is that the same company can score well with one agency and poorly with another. We examine why ESG ratings diverge in detail.

AI helps automate data collection, estimate Scope 3 categories where primary data is missing, and flag anomalies before disclosure. It does not remove the need for human review, particularly where estimates feed audited reporting. Our piece on AI in ESG reporting covers the benefits and the risks.
