HomebuildersCAN supports members across three key areas

Increased home performance. Profitable practices. Building sector alignment. The program is designed with flexibility to support homebuilders in each of these areas no matter where they are in their embodied carbon journey, from those just learning about what embodied carbon is to those with built example-demonstrating reductions. As a member, you'll work alongside experts and leading practitioners to:

why focus on embodied carbon?

Emissions from materials for new homes in the United States is equivalent to the total emissions from entire countries (RMI Report 'Hidden Climate Impact of Residential Construction').

Using less material and choosing materials wisely can significantly reduce the embodied carbon of a home, often without raising costs. Homebuilders can take immediate steps to achieve 30 to 50 percent emissions reductions with commercially available, affordable, and code-compliant building materials and by targeting just a few key material categories: concrete, insulation, cladding, and interior surfaces.
