Bill Summary · HB 4773

Legislative bill overview

HB 4773 proposes to establish a "Climate Change Superfund" in Illinois that would require major polluters and fossil fuel companies to contribute financially to a dedicated fund addressing climate change impacts and environmental remediation. The bill aims to create a dedicated revenue stream specifically for climate-related damages and mitigation efforts within the state.

Why is this important

Climate-related damages—from flooding and extreme weather to air quality degradation—impose significant costs on communities and public budgets. A dedicated superfund mechanism could provide sustained funding for climate resilience infrastructure, environmental cleanup, and adaptation measures without drawing from general revenue, potentially offering more stable long-term planning for climate response.

Potential points of contention

  • Economic impact concerns: Industries designated as contributors may argue the financial burden will increase operational costs, potentially leading to higher consumer prices or reduced competitiveness
  • Definition and scope disputes: Determining which companies qualify as "major polluters" and how liability is calculated could face legal challenges and implementation debates
  • Revenue adequacy: Questions about whether the fund will generate sufficient revenue to meaningfully address Illinois's climate needs, or if it represents primarily symbolic action
