Puro.earth is the world’s leading market infrastructure provider for engineered carbon dioxide removal (CDR). Backed by Nasdaq, we provide the certification frameworks, scientific standards, and digital systems that allow engineered CDR to scale and operate as an investment-grade market.
At the core of this infrastructure is the Puro Standard - the world’s first dedicated standard for engineered carbon removals. Our methodologies are used by suppliers to certify their carbon removal solutions that durably store carbon dioxide for at least 100 years, and in many cases, over 1000 years. We have certified over 100 engineered carbon removal projects to date, resulting in the issuance of CO₂ Removal Certificates (CORCs) in the Puro Registry as verified, traceable, investable assets.
Our infrastructure is trusted by over 600 companies worldwide to purchase carbon removals with confidence, including Microsoft, McKinsey and BCG. It supports both voluntary and compliance pathways, including integration with CCS+ methodologies and readiness for emerging frameworks such as the EU CRCF.
