A U.S. Department of Energy (DOE) pilot project is in the works to measure the greenhouse gas (GHG) intensity of certain industrial products or materials, likely led by cement, steel, aluminum and glass. The move coincides with a greater emphasis on “clean” manufacturing and the need among companies, government officials, trading partners and consumers for a fair, coherent system to…
