A powerful new mapping tool for environmental justice

Colorado EnviroScreen is an interactive environmental justice mapping tool. Version 1.0 of Colorado EnviroScreen launched on June 28, 2022.

The tool enables users to identify disproportionately impacted communities based on the definition in Colorado’s Environmental Justice Act (HB21-1266) so that communities directly benefit from:

  • Money and other resources. For example, CDPHE’s Environmental Justice Advisory Board will use EnviroScreen to determine where to distribute environmental justice grants created by the new law.
  • Enhanced opportunities to participate in Air Quality Control Commission rulemaking and permitting decisions.
  • Priority for enforcement and compliance initiatives under an agreement between CDPHE and the U.S. Environmental Protection Agency.
Driven by community

Community voices and expertise were vital to making Colorado EnviroScreen useful to communities disproportionately impacted by environmental health risks. We engaged with more than 200 people in the course of developing Colorado EnviroScreen.

Community engagement for Colorado EnviroScreen prioritized disproportionately impacted communities across Colorado that have known or suspected disproportionate health risks from cumulative environmental exposures. Federal, state, local, and tribal governments, environmental justice organizations, community organizations, and businesses all provided input. The Colorado EnviroScreen team conducted stakeholder interviews, focus groups, and large community meetings, and has used that input to shape functionality and user experience.

We’re committed to continuous improvement with Colorado EnviroScreen. By listening to people’s lived experiences and tapping into community expertise, we can ensure Colorado EnviroScreen is a trusted tool that reflects the needs of the people and organizations it is intended to benefit. You can provide feedback at any time.



On August 31, we corrected a bug that caused 6 census block groups that meet the definition of disproportionately impacted community to display as not meeting the definition in the data table within EnviroScreen.  These block groups are now correctly displayed in all COEnviroScreen data.  Note that prior to the bug fix, these census block groups did correctly display as disproportionately impacted communities on the DI Community Data Viewer, Climate Equity Data Viewer, and in the DRAFT Disproportionately Impacted Community GIS layer available for download on CDPHE's Open Data page. The bug only existed within Colorado EnviroScreen, data downloaded directly from Colorado EnviroScreen, and CDPHE Open Data GIS block group level EnviroScreen data. If you accessed disproportionately impacted community data from Colorado EnviroScreen for any of these census block groups prior to August 31, please re-download the data:
