## In brief

- San Francisco Bay Area regulators have finalized a long-awaited rule limiting pollution from residential water heaters.
- In 2023, the Bay Area Air District board passed first-in-the-nation regulations setting zero nitrogen oxides (NOx) emissions standards for new home water heaters.
- The finalized rule aims to boost adoption of heat-pump water heaters.

## Why it matters

Setting zero-NOx standards for new residential water heaters is a first-in-the-nation regulatory approach that cuts indoor and outdoor air pollution from gas appliances and may serve as a model for other regions.
