In their new op-ed in RealClearEnergy, Hessam AzariJafari, Ipek Bensu Manav, and Andrew Laurent explain that while the U.S. Environmental Protection Agency (EPA)’s new low-carbon labels for construction materials are an important step forward, they must account for emissions beyond production to best aid purchasing decisions. The authors propose that the EPA use life cycle assessment tools to generate actionable emissions ranges that account for context and climate, and also expand the range of materials covered under the labeling program.
