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.
