Colorado EnviroScreen Community Workshops

Join the Environmental Justice Program for a Colorado EnviroScreen community workshop! 

This online workshop will take place on Friday February 3rd, 11:00 AM to 1:00 PM

Register here to attend!

At the workshop, community members will learn:

  • What Colorado EnviroScreen is;
  • What data the tool includes and doesn’t include;
  • How to use the tool;
  • How to understand what the data about your community means.

CO EnviroScreen is Colorado's new bilingual interactive environmental justice mapper. CDPHE developed it in collaboration with Colorado State University. CO Enviroscreen combines 35 environmental, health, and demographic indicators. It visualizes areas in Colorado with higher environmental and socioeconomic burdens. The tool also shows places that meet the legal definition of a Disproportionately Impacted Community.



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 January 23, 2023, we updated the Disproportionately Impacted Community layer to include block groups that meet the cumulative impacts component of the definition of Disproportionately Impacted Community in the Environmental Justice Act.  Based on the recommendations from the Environmental Justice Action Task Force, these are census block groups that have an EnviroScreen Percentile Score above 80. This added 79 block groups to the DI Community layer.
An archived version of the DI community layer is available upon request.  Please note that if you are accessing the Disproportionately Impacted Community layer as part of a regulatory requirement adopted prior to January 2023, you should review the specific requirement to determine whether it includes areas that meet the cumulative impacts prong of the definition, or whether the regulation only includes areas the meet the demographic prong of the definition. Areas that meet the demographic component of the definition are still displayed in Colorado EnviroScreen, so you can still use the current version of the tool to identify these areas.  Just make sure you note whether the census block group meets the definition of DI Community under one of the demographic factors or under the cumulative impacts prong. 

On August 31, 2023, 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, 2023, please re-download the data:
