The Coalition on Materials Emissions Transparency (COMET)

To further and fully understand how to plan for the decarbonization of mining value chains, we need better data on carbon and other greenhouse gas (GHG) emissions. However, neither consumers, corporates, or financial institutions know the embodied emissions in the products they produce or sell. While methods like life-cycle analysis and environmental product declarations exist, none use a verifiable, comparable, or widely adopted emissions reporting framework capable of sending supply chain signals.

To truly reform material supply chains, new solutions for markets, capital, and policy are required. COMET (the Coalition on Materials Emissions Transparency)—an alliance launched at Davos in January 2020 by CCSI, RockyMountain Institute, MIT’s Sustainable Supply Chains initiative, and the Colorado School of Mines—is creating a harmonized GHG calculation framework applicable to all mineral and industrial supply chains.
