    Leading the World in Carbon Removal

    Puro.earth: The World's Leading Carbon Removal Platform

    Growing Nasdaq's ESG offering to support corporate client sustainability efforts
     

    The Race to Net-Zero

    Transitioning to a net zero emissions economy is crucial to mitigating the worst effects of climate change. But it won't stop there. To truly make a difference, we must actively decrease CO2 concentrations in the atmosphere, aiming for pre-industrial levels through net-negative emissions.

    In 2021, Nasdaq acquired a majority stake in Puro.earth, the world's leading platform for engineered carbon removal. Puro.earth are scaling the Carbon Dioxide Removal (CDR) industry by connecting buyers with suppliers physically capturing CO2 from the atmosphere and stabilizing it in a durable storage.

    Together, we will fuel a global scale-up phase of carbon removal that will create a world where companies are part of the change to combat climate change, while bringing trust, integrity and transparency to the solution.

    CORC Carbon Removal Price Indexes

    The CORC Index family is the world’s first indexes to focus exclusively on tracking the price of carbon removal from the atmosphere.

    Nasdaq in collaboration with Puro.earth have created three commodity reference price indexes, based on Puro.earth's Carbon Removal Certificates (CORCs). The objective is to increase transparency in the carbon removal market, helping corporates understand the cost of cutting their carbon emissions and supporting more informed project financing decisions.

    The Index family consists of a composite index that tracks the price of all carbon removal transactions as well as a separate index for biochar and bio-based construction materials.
