Mapping air quality across the Bay Area

The Bay Area Air Quality Management District is working with Aclima to assess and analyze block-by-block measurements of air quality and greenhouse gases across all nine counties and 5,000 square miles of the San Francisco Bay Area. This groundbreaking capability strengthens and targets the District’s efforts to ensure access to clean air for nearly 8,000,000 residents. 




This work will help shine a light on the disparity of health impacts faced by many in the region and it will inform lawmakers to better guide our decision-making process to protect the health of all Bay Area residents moving forward.
