Developed as a new US and Canadian standard, CarbonStar® To Help Decarbonize Concrete and Slow Climate Change
WASHINGTON, D.C., October 30, 2024 - The Smart Surfaces Coalition, CSA Group (formerly the Canadian Standards Association), the World Cement Association, and the American Public Health Association announce the introduction of CarbonStar®, a new binational standard to quantify the carbon impact of concrete. CarbonStar [CSA/ANSI R118:2024, CarbonStar®: Concrete Carbon Intensity Quantification and Verification] provides a simple, rigorous way to compare the embodied carbon in concrete. Concrete is the most-used building material on the planet and is responsible for 8% of global greenhouse gas emissions.
