Today Nasdaq (Nasdaq: NDAQ) launched new carbon removal indexes, the first of their kind to track the price of removing carbon dioxide CO2 from the atmosphere, using Carbon Removal Certificates (CORCs) issued by Puro.earth. 
Adding these indexes supports the need for transparency, evaluates methods for carbon removal, standardizes processes, and spurs investment. The new indexes are effective as of March 24, 2022.
Puro.earth is a pioneer in the B2B marketplace for carbon removal. Its primary index is the CORC Carbon Removal Price Index (CORCX), which evaluates the cost of sequestering one ton of CO2 using supported carbon removal methods approved by Puro Standard. Nasdaq acquired a majority stake in Puro.earth in 2021.
Additional indexes include the CORC Biochar Price Index (CORCCHAR) for carbon removal in biochar and CORC Bio-based Construction Materials Price Index (CORCWOOD), which evaluates bio construction materials like wood.
