Advancing Policy

Advancing Policy


A group of people are standing around a table in a room.

We convene green building professionals to advance high performance buildings for all.

Reducing building emissions is crucial for meeting state and local climate goals.


To overcome barriers to net zero adoption, we will engage our network of building professionals to develop new policies, like net zero building codes and building performance standards, and educate policymakers about meaningful solutions that will help overcome roadblocks and incentivize net zero buildings.

Our Current Policy Goals


Clean and Affordable Buildings Ordinance (CABO) - Chicago

In early 2024, Mayor Brandon Johnson and 15 co-sponsors introduced an ordinance that would limit carbon dioxide emissions in new-construction to reduce climate impacts and protect residents from the negative health impacts associated with natural gas. The ordinance would prohibit fuels that emit more than 25 kg/btu of Co2, promoting cleaner energy sources.
