Buildings are a major driver of global heating, contributing 37% of all greenhouse gas emissions. While we know how to reduce operational carbon to net zero, cutting embodied carbon—half of a building’s lifetime emissions—remains a daunting challenge. Our new research reveals that although it’s possible to significantly lower embodied carbon, achieving this in Australia will require radical changes in building design, construction, and reuse. As operational carbon decreases, embodied carbon’s impact will only grow, potentially comprising 85% of building emissions by 2050. The path to a low-carbon built environment demands bold action now.
