All that activity emits a lot of carbon, of course, which is why improving energy efficiency is so important. But a less visible source of building emissions is also starting to attract more attention these days: the “embodied carbon” in the structure itself, a result of the carbon-intensive processes involved in producing construction materials in the first place.
“When jurisdictions have climate goals, they’re looking for ways to reduce emissions,” said Webly Bowles, who manages projects and does research at the New Buildings Institute (NBI), an organization that supports efforts to improve energy efficiency and decarbonize the built environment. In some cases, Bowles said in an interview, that may mean changing procurement policies to require a lower carbon content in concrete and other building materials.Read More
