Policy Primer Educational Series

Policy is an essential step towards creating the scale of action required to rapidly reduce embodied carbon in construction. The policy primer series below begins with an introduction to procurement policies, also known as Buy Clean. Keep checking back to see additional primers on other policy areas.

Several key forms of embodied carbon policies to look out for in 2021 include:

  • Procurement policies (like Buy Clean and material-specific variations)
  • Climate Action Plans
  • Building codes
  • City zoning, land use, and building regulations and incentives, including building and material reuse policies
  • Executive orders addressing embodied carbon of building and industrial sector emissions
