A new study by One Click LCA reveals a significant gap in the construction supply chain, where 90 percent of architects and engineers prefer materials with Environmental Product Declarations (EPDs), but only 22 percent of manufacturers provide them for most of their products. This data is critical for reducing embodied carbon in buildings, which account for roughly 40 percent of global emissions. Industry experts suggest that transparent product data could reduce embodied carbon in construction by up to 30 percent. The most effective carbon reductions happen during the early design stages when professionals choose low-emissions materials, such as recycled-content metals, before construction begins.
