Step 1: Investigate the problem

Identify and prioritize pollution sources

Information on pollution sources and emissions comes from several types of data, including self‑reported data, continuous monitors and satellite observations. Modeling tools, such as the EPA’s MOVES model, are another powerful tool that your city can tap into to estimate or even predict pollution from specific activities, such as transportation or energy generation.

Together, these tools help cities identify where pollution is coming from, how much is released and which sources contribute most to poor air quality. They provide the insights that cities need to make the case for new policies and to focus resources where they will have the greatest impact. Check out our curated list of featured tools below to begin identifying your city’s top pollution sources.
