Across the U.S., states are working to develop policy and regulatory frameworks to accelerate an equitable clean energy transition. Zero-emission heating equipment standards (ZEHES) are an emerging regulatory approach aimed at addressing GHG emissions and air pollution from buildings, requiring the phase-out of sales of new climate-polluting fossil fuel-fired equipment.

This research brief provides an overview of the history of emissions-based equipment standards in the U.S. and the action currently being taken to advance zero-emission equipment standards in other states. It also presents considerations for adapting this type of regulatory approach in the context of Vermont’s existing housing stock.
