Puro.earth Issues Two Millionth CO₂ Removal Certificate
The milestone reflects growing verified carbon removal supply as buyers retire more than one million certificates.
Updated on Nov. 5, 2026 in Organic Food
Puro.earth has issued its two millionth CO₂ Removal Certificate, known as a CORC, with each certificate representing one tonne of carbon dioxide removed from the atmosphere and durably stored. More than 1 million CORCs have been retired by more than 900 buyers.
Why it matters
The milestone signals that verified carbon removal is scaling in the market, giving buyers and investors a growing track record of independently certified supply. The pace of issuance has accelerated, with the second million taking about 19 months compared with about five years for the first 500,000.
Puro.earth issues more than 50,000 CORCs per month on average, and every certificate requires at least 100 years of storage. Biochar accounts for 49% of issuance and geologically stored carbon for 31%, while more than 900 buyers have retired over one million certificates.
The players
Puro.earth
Puro.earth is a carbon removal certification body that independently verifies and issues CO₂ Removal Certificates to certified suppliers.
The details
Puro.earth certifies more than 100 suppliers across eight methodologies and issues CORCs only after independent verification of carbon removal. The organization says verified delivery histories can help buyers commit to larger offtakes and help investors back new capacity.
Timeline
About five years before the milestone, the first 500,000 CORCs were issued.
About 19 months before the milestone, issuance of the second million CORCs began.
Market Landscape
Within the Puro.earth CORC scheme, the milestone shows verified durable carbon removal moving from early certification toward a larger, more established supply base. The shorter issuance interval for the second million suggests the scheme's delivery capacity is compounding.
For readers who buy carbon offsets or follow sustainability claims, Puro.earth's verified certificates provide a traceable record of removal rather than unverified promises. The certification process gives buyers a documented basis for comparing suppliers.
The takeaway
Independent certification and verified delivery histories are becoming the basis for trust in carbon removal claims. Buyers evaluating offsets can prioritize certificates backed by traceable, third-party verification.
