CalEnviroScreen 5.0
The Office of Environmental Health Hazard Assessment (OEHHA) has developed CalEnviroScreen (CES) 5.0, the latest iteration of the California Communities Environmental Health Screening Tool. This version of CES incorporates the most recent publicly available data for all indicators and improves the way some indicators are calculated to better reflect environmental conditions or a population’s vulnerability to environmental pollutants. Two new indicators—Small Air Toxic Sites and Diabetes Prevalence—were added to help capture additional environmental burdens and disease that contribute to pollution burden and population sensitivity to pollution. The indicator of Small Air Toxic Sites accounts for the presence of oil and gas wells and other sites reporting air toxic releases that are not already captured in the existing indicator of toxic releases. A Diabetes Prevalence indicator reflects sensitivity to pollution as exposure to pollution leads to worsening health outcomes for individuals with diabetes. This version of CES has been updated with additional information to incorporate pollution concerns in the California-Mexico border region, continuing the efforts to address Assembly Bill 1059 (Garcia, Statutes of 2015). For the latest iteration of CES, OEHHA partnered with community-based organizations (CBOs) to co-design key updates to the tool and to continue its commitment to meaningful community engagement. A full report on the co-design process and a short overview report summarizing changes and updates for CES 5.0 are available on the CES 5.0 webpage along with a technical report describing the changes and updates in more detail. To download data in different formats, visit the CA Open Data Portal.
