A new study by MIT Concrete Sustainability Hub (CSHub) researchers shows that the annual greenhouse gas (GHG) emissions of all construction materials used in the U.S. pavement network are 11.9-13.3 megatons, equivalent to the output of a gasoline-fueled passenger vehicle logging 30 billion miles. As roads are built, repaved, and expanded, new approaches and thoughtful material choices are necessary to…

MIT CSHub reviews carbon uptake mechanisms in concrete
Sources: Massachusetts Institute of Technology Concrete Sustainability Hub, Cambridge; CP staff The process by which cement-based products sequester carbon dioxide is key to understanding the life cycle impacts of the world’s most widely subscribed building material. In a three-point question & answer sequence, MIT Concrete Sustainability Hub Deputy Director Hessam AzariJafari describes how CO2 uptake is a key lever in the…
