Puro Registry for durable carbon
removal credits

On the Puro Registry you can view CO2 Removal Certificates, or CORCs, that have been retired and the projects that issued them. CORCs are retired when a beneficiary makes a net zero or carbon neutrality claim that is supported by the CORCs’ carbon removal properties. Each CORC represents a Net Carbon Dioxide Removal volume of one (1) metric ton of Long-Term CO2 Removal.
