What is the Wisconsin Environmental Equity Tool?

The Wisconsin Environmental Equity Tool (WEET) is a comprehensive web-based environmental justice and health equity mapping tool that is being developed by four state agencies in consultation with other organizations, community members and local government.

The tool will combine, analyze and visualize data online, so government and tribal agencies, community-based organizations, and the public can pinpoint Wisconsin’s most impacted communities, The tool will help all users better understand the challenges impacted communities face from pollution, a changing climate, socioeconomic factors, and other environmental and health hazards.

What's new?

Check back often for updates on the WEET project. Here's what's new:


We Want to Hear From You!

We want to ensure the mapping tool reflects your real-world experiences, especially Wisconsin’s communities of color, low-income communities, rural communities, Tribal Nations, and immigrant communities, who are often burdened with the greatest environmental and health consequences and inequities. You are the expert on your experiences, and we want to learn about your successes, challenges, and needs, as well as what you hope to see in the new tool. There are several ways you can share your experiences and ideas:

  1. Four happy adults with two smiling children hiking on a path.Send written comments or questions to

  2. Attend a meeting of the WEET Ad Hoc Advisory Committee on June 29, 2022, from 6–7:30 p.m. Listen in via Zoom or toll-free phone call at 877-873-8018, code is 248199. You can email any comments or questions to or use the Zoom chat.

  3. Sign up for project update emails to stay informed.

State leaders hosted three virtual pubic listening sessions in November. Summary reports are now available for listening sessions, general public survey, and public sector survey.

Wisconsin Environmental Equity Tool Purpose and Scope

The purpose of the Wisconsin Environmental Equity Tool is to provide a state-specific environmental equity screening and mapping tool using more detailed local and state data to better characterize local conditions in order to help policy-makers, service providers, communities and stakeholders:

  • Better understand areas of environmental, public health, and climate vulnerability;
  • Focus local and state programs and policies to advance environmental equity; and
  • Inform funding priorities and awareness activities.

Potential Uses

A wide range of stakeholders – from community members, government officials, elected officials, public health professionals, to nonprofits – can use the Wisconsin Environmental Equity Tool to build community awareness and educational campaigns, inform policy and program planning, prioritize funding for investment and interventions, conduct community health assessments, write data-driven grant proposals, strengthen community organizing efforts, and more.

Partnerships and Collaborations

The Wisconsin Environmental Equity Tool will help Wisconsin meet its commitment to reduce health inequities and advance environmental equity. The primary state agencies leading the development of Wisconsin Environmental Equity Tool, include:

  • Department of Administration (DOA)
  • Department of Health Services (DHS)
  • Department of Natural Resources (DNR)
  • Wisconsin Economic Development Corporation (WEDC)

The project team will be inviting additional partners to join a project advisory committee to seek ongoing advice and recommendations from a wide range of community members and professionals.

Examples of Environmental Justice Screening and Mapping Tools

Experts in the field of environmental justice or environmental equity have evaluated data-driven, geospatial tools developed by several states and the federal government to identify and learn about communities’ environmental and climate change burdens, which often exacerbate other systemic inequities. Washington State, California, and Maryland use the most comprehensive approaches to environmental justice screening, taking into consideration disproportionate, cumulative impacts, and the reality that communities of color, low-income communities, rural communities, Tribal Nations, and other indigenous communities are often burdened with multiple environmental problems that also impact people’s health.

A methodology for environmental justice screening that creates a transparent scoring or index procedure to examine cumulative impacts and social vulnerability holistically enables organizations to make informed, strategic decisions to confront these problems head-on to improve the health, resilience, and sustainability of overburdened communities.

Potential Data to be Included in WEET

WEET is still in the beginning of the planning stages. Public input throughout the project will help shape the tool design, identify data needs and analysis solutions, as well as continuous upgrades and maintenance needs over time.

One of the first steps in the development process is to evaluate available data. Similar tools developed in other states included economic, social, environmental, climate change, health, and other relevant data that is easily accessed. A list of Wisconsin data currently available through state and federal databases are listed below, and they may be included in WEET if they meet data quality and compatibility standards. Much of this data is already available in a map format on the Department of Natural Resources website.
