New initiative to track GHG emissions in materials supply chain

Rocky Mountain Institute, MIT Sustainable Supply Chains, the Columbia Center on Sustainable Investment, and the Payne Institute for Public Policy at the Colorado School of Mines have announced the Coalition on Materials Emissions Transparency (COMET). This effort aims to build a standard method for measuring greenhouse gas (GHG) emissions in materials, “an important step in decarbonising mineral and industrial supply chains”, the partners said. The COMET method will provide insight into the carbon content of consumer products like cars, buildings, and phones, and will help both corporations and consumers purchase materials and products with fewer embedded CO2 emissions, according to the partners.
