Our Approach

Science & Analysis

We’re not just advocates—we’re experts. As the only environmental group in Wisconsin with a dedicated science team, we have the knowledge and credibility to fight smarter and win bigger. Backed by research and legal expertise, we turn advocacy into impact.

Leading with Science

Our Approach

Legal Action

For decades our legal team has fought and won high-impact cases to protect Wisconsin’s air, water, and natural places—from curbing agricultural runoff to challenging weak air pollution permits. When policy fails, we use the power of the courts to defend the environment and public health.

Defending Wisconsin’s Environment

Our Approach

Policy Advocacy

We work with lawmakers, agencies, and communities to advance environmental policies that protect Wisconsin’s air, water, land, and climate—guided by science and driven by our shared vision for a clean Wisconsin.

Shaping Policy

Our Approach

Community Engagement

From severe storms to smoke-filled skies, climate change is already affecting communities across Wisconsin. Clean Wisconsin partners with local governments and community organizations to prepare for extreme weather, reduce pollution, and build long-term resilience—starting with the people most impacted.

Community Engagement in Action

Our Approach

Amplifying Your Voice

Real change starts with people who speak up. Clean Wisconsin helps people across the state take meaningful action—whether it’s contacting legislators, attending hearings, or organizing in their communities to protect our air, water, and climate.
