ETC Explorer

The Justice40 initiative, created by the Biden-Harris Administration through Executive Order 14008 Tackling the Climate Crises at Home and Abroad, is a key component in USDOT’s efforts to confront and address decades of underinvestment.  When decision makers at all levels have the tools to understand how a community is experiencing disadvantage and can identify projects that create benefits that will reverse or mitigate those causes, the result is a higher quality of life and economic prosperity in communities across the country.  

The US DOT Equitable Transportation Community (ETC) Explorer is an interactive web application that uses 2020 census tracts and data, to explore the cumulative burden communities experience, as a result of underinvestment in transportation, in the following five components:  Transportation Insecurity, Climate and Disaster Risk Burden, Environmental Burden, Health Vulnerability, and Social Vulnerability.  It is designed to complement CEQ’s Climate & Economic Justice Screening Tool by providing users deeper insight into the Transportation disadvantage component of CEJST, and the ETC Explorer’s Transportation Insecurity component, which will help ensure the benefits of DOT’s investments are addressing the transportation related causes of disadvantage.  Applicants to USDOT's Justice40 covered program NOFOs should use CEJST as the primary tool to identify disadvantaged communities, as USDOT’s ETC Explorer is not a binary tool indicating whether a census tract is considered disadvantaged; it is a dynamic tool that allows every community in the country to understand how it is experiencing burden that transportation investments can mitigate or reverse.
