AN ACT CONCERNING A CLIMATE CHANGE SUPERFUND.

HB 5156 establishes a Climate Superfund Cost Recovery Program to fund climate adaptation projects by holding fossil fuel entities accountable for historical emissions. It targets fossil fuel companies (defined as entities extracting or refining fossil fuels during 1995-2024 that caused over 1 billion metric tons of emissions) to pay into a fund, rather than using taxpayer money. The fund finances specific climate adaptation projects, including coastal wetland restoration, stormwater system upgrades, urban heat mitigation, and protecting food systems from climate impacts, with priority for environmental justice communities. Projects must align with "nature-based solutions" like green infrastructure and energy-efficient retrofits for public buildings. The program is administered by the Department of Energy and Environmental Protection, starting October 1, 2026.
