Baking for the Climate!

We can fight climate change in Wisconsin by rethinking what we grow and eat. Clean Wisconsin partnered with Madison’s Bloom Bake Shop to create some delicious treats made with two new Wisconsin crops that could be game changers for our environment: Kernza® perennial grain and American hazelnuts.

In the wake of Milwaukee’s catastrophic 2010 flood, Clean Wisconsin and other community partners have engaged thousands of residents to install green infrastructure like rain barrels and rain gardens, capturing more than 2 million gallons of storm water per year.

This summer, we hit a major milestone—we installed our 700th rain barrel!

PFAS Pollution in Wisconsin

Everyone should be able to eat the fish they catch and drink the water flowing from their taps. But in Dane County and dozens of other communities across the state, PFAS contamination is putting our waterways at risk. These chemicals surround us – in carpeting and upholstery, clothes, shoes, firefighting foam, fast food wrappers, ski wax, non-stick pots and pans, and the list goes on. Clean Wisconsin is pushing for meaningful progress at all levels.

Wisconsin’s First Solar Neighborhood

A look inside the first and so-far *only* net-zero electricity solar neighborhood in the state of Wisconsin! All of these New Berlin, Wis. homes are certified through Focus on Energy’s New Home Certification Program. But there is so much more work to be done. We need more state & federal investment to make solar more accessible and affordable for everyone. Now is the time to fight the climate crisis and build a clean energy future.

Vicious Cycle: The Struggle for Clean Water

More than two-thirds of Wisconsinites use groundwater as their drinking water source, but what happens if that water is contaminated? Over 80,000 private wells across the state are contaminated with high levels of nitrates, limiting resident’s access to clean drinking water and putting their health at risk. Homeowners, like Steven Shoemaker and Elisabeth Minich, are then on the hook for thousands of dollars to try and clean the water, but they say it should not be their responsibility.


We’ve got a responsibility to leave our water, air, and natural resources in a better place for our kids than we found it.
