Peatlands are waterlogged wetlands that accumulate peat—organic material storing immense carbon reserves. Globally, they cover just 3% of land yet hold more carbon than all forests combined, and in Wisconsin, they are the most carbon-dense ecosystem in the state. Restoration of degraded peatlands in Wisconsin could cut 2.3 million metric tons of CO₂ annually—roughly equal to removing 500,000 cars from the road—while safeguarding biodiversity, filtering water, and protecting communities from floods and fire. Investing in peatland protection and restoration has the potential to deliver one of Wisconsin’s most impactful strategies for climate mitigation and resilience.
