Bay Area Sets NOx Emissions Standards For Gas Water Heaters & Furnaces, Effectively Ending Sales Starting In 2027

Published by CleanTechnica: Big news for clean air last week. The Bay Area Air Quality Management District (BAAQMD) adopted amendments requiring the elimination of nitrogen oxide (NOx) emissions from new water heaters by 2027 and new furnaces by 2029.

The new Bay Area emissions standards will be one of the first in the nation to phase out existing gas and fossil fuel water heaters. New Buildings Institute helped write building codes which were adopted in 2022 in Washington State that mandate heat pumps for space and water heating in new construction.
