A powerful new mapping tool for environmental justice

The Colorado Department of Public Health and Environment (CDPHE) and a team at Colorado State University are gathering pre-launch feedback on an enhanced environmental health screening tool for Colorado. This interactive mapping tool is called Colorado EnviroScreen. The tool will launch in early summer.

Colorado EnviroScreen will enable users to identify disproportionately impacted (DI) 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, the Environmental Justice Advisory Board at CDPHE 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 emissions reductions during climate-related air quality rulemakings.
  • Enhanced emissions monitoring and modeling for air pollution permits.
  • 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 are vital to making Colorado EnviroScreen of service to communities disproportionately impacted by environmental health risks. We have engaged with more than 200 people so far.

Community engagement for Colorado EnviroScreen prioritizes DI 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 also are providing 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.

Interim environmental justice mapping tools

The Environmental Justice Act defines disproportionately impacted communities as including low-income communities, communities of color, and housing cost-burdened communities. Stakeholders can use the Climate Equity Data Viewer or the Data Viewer for Disproportionately Impacted Communities to identify census block groups that meet those three criteria until Colorado EnviroScreen launches early this summer. The Data Viewer for Disproportionately Impacted Communities is an interim tool that CDPHE is using while CO EnviroScreen, which will consider the broader components of the definition, is being developed.  
Colorado EnviroScreen will replace this interim tool when it is finalized. It will be a one-stop mapping tool that includes the Environmental Justice Act’s full definition of disproportionately impacted communities. Colorado EnviroScreen also will improve upon the Climate Equity Data Viewer.
