Calgary-based Enbridge, Inc. is seeking permits from the Department of Natural Resources that would allow the company to reroute Line 5 across dozens of northern Wisconsin waterways and more than 100 acres of wetlands.

The plant would add 3-million tons of carbon pollution into the environment each year, pushing us even further from our climate goals and harming the health of people who live nearby. Its construction would destroy 20 acres of wetlands. Learn More

We’re propelling Wisconsin into a new era of energy independence and clean jobs by encouraging a switch to solar and wind energy, accelerating clean transportation, and championing energy efficiency programs that reduce energy use.

Hydration is her beauty secret

Everyone deserves clean, safe water. From protecting drinking water from lead, PFAS and nitrate contamination to defending our state’s critical wetlands, we are the leader in protecting Wisconsin's invaluable water resources.

We can’t always see or smell toxic air pollutants in the air we breathe, but their health impacts are very real. Clean Wisconsin has been fighting for clean air for more than 50 years. Our work has had a direct impact on air quality regulations here in Wisconsin.

Clean Wisconsin is working with Wisconsin communities to build a cleaner, healthier future. We are scaling up the use of green infrastructure through education, outreach, policy, and on-the-ground installation of rain barrels and rain gardens. And we’re educating decision-makers about climate smart building and farming practices.
