The construction industry will never reach carbon zero. And while we have made great strides in the way of operational emissions, we have only begun to think about reducing the embodied carbon emissions associated with the manufacturing, transport and construction of the necessary building materials. In most cases, it takes 250 years of operation to match the emissions related to the building process itself. So how do we reduce embodied carbon emissions as much as possible—and responsibly offset the rest?
