Drivers who helped collect data for Richmond - San Pablo

What We Did

• We measured important air pollutants across Richmond-San Pablo: PM 2.5, ozone, nitrogen dioxide, nitric oxide, carbon monoxide, and carbon dioxide.

• From August 1 through October 31, 2019, we generated 110 million data points, collected over 25,000 miles.

• Richmond-San Pablo is being mapped as part of an ongoing Bay Area-wide program that will measure hyperlocal air pollution in all nine counties, including Contra Costa County.

• We designed the following interactive report to show average air pollution and greenhouse gases at the street level.

• See below for a map of average PM 2.5 concentrations in the area with points of interest called out. Scroll down to look up average hyperlocal pollutant levels by address.

In Detail - Location by Pollutant

Hyperlocal air quality mapping is a new capability. California and National air quality standards are calculated using a small number of stationary monitors and averaged over specific time periods, typically every 24 hours and yearly. Aclima’s method is different — we cover every street with multiple passes for quarterly averages at very precise locations. However, government standards help provide context about what pollution levels are of concern.

PM 2.5
PM 2.5 Average: 9 µg/m³

Emitted directly from a combustion source or formed in the atmosphere from complex chemical reactions, particulate matter (PM2.5) is one of the primary pollutants public health officials care about because it is linked to asthma, lung cancer, and deaths from cardiopulmonary diseases. You can reduce your exposure to PM2.5 by staying indoors, particularly in buildings with good ventilation and filtration systems. If outside, reduce overall activity levels.

Next steps - What you can do

Whether you only have a few seconds or you want to devote more time to reducing air pollution, we’re building a library of actions you can take. Got a great idea you want to share? Let us know!

Three things you can do right now:
  1. Protect your health and do your best to limit your time in higher-polluted areas identified on the Aclima hyperlocal air quality map.
  2. Make plans to join the next Community Air Protection Program monthly Steering Committee meeting or email Kristen Law to get involved.
  3. If you are a young leader and have feedback you'd like to voice, connect to organizations like RYSE, and adult allies about the best way to share your thoughts and get involved.
Three things you can do this week:
  1. If you see something that you think is causing more pollution than it should, submit a complaint to your Bay Area Air Quality Management District.
  2. Get involved locally through groups like First 5 which advocates for policies focused on children during their first five years, and RYSE, a youth center born out of the organizing efforts of Richmond and West County young people.
  3. Follow and share your ideas on the Air District’s Open Air Forum.
Three things you can do long-term:
  1. Let your local government know that clean air matters to you. Any member of the public can participate during the regularly scheduled public board of supervisors meetings.
  2. Look for ways to get involved in reducing air pollution through online resources from local organizations like
  3. Learn more about the connections between air pollution, human health and climate change, and spread the word!
