Tar Sands

The Tar Sands Campaign mobilizes people to oppose new oil pipelines in WI. Our current goal is to block Enbridge’s rerouting of Line 5 in the Lake Superior watershed. We support efforts led by those most impacted, including tribes, landowners, and community members.

Divest & Defund

The Divest & Defund Team works to convince institutions that investments in fossil fuels are not only ethically and fiscally irresponsible, but are literally wrecking the planet we call home—all for profit. We are currently focusing on banks that fund pipeline projects.

Climate Solutions

Community Climate Solutions focuses on making change across Dane County, targeting both systems and individual levels. We assist local governments to achieve climate goals. We broaden and deepen citizen climate crisis awareness and action.
