Air Quality Data Directory

Knowing how to find and use relevant air quality data has proven to be a challenging barrier for data-informed legal action and clean air advocacy. To help address this challenge, EDF has created a central directory of both air pollutant emissions databases and associated tools.

This searchable, filterable database allows users to learn more about each database and tool. EDF developed this inventory in collaboration with partners and clean air advocates, prioritizing databases and tools that are the most user-friendly and relevant for advocacy. 

Disclaimer: Some of the following datasets and tools are no longer available. See this page for a running list of data archives, backups, and workarounds.

Would you like to see a specific resource added to our directory? Please fill out this form or email us.
