Louisiana among 24 states in lawsuit against Vermont ‘Climate Superfund’ law
- Louisiana joined 23 other states in filing a lawsuit against Vermont's 2025 Climate Superfund Act, challenging its penalties on fossil fuel producers and consumers.
- The states contend Vermont's law retroactively imposes extraterritorial liabilities that infringe on constitutional rights and federal authority over national energy policy.
- The Climate Superfund Act, enacted in early 2025, enables Vermont to hold fossil fuel producers financially responsible for climate-related harm experienced within the state from 1995 through 2024, regardless of where the emissions were originally released.
- The lawsuit claims the law is a "shakedown" that violates due process, equal protection, and constitutes an excessive fine, while Vermont's own emissions from wood burning remain unpenalized.
- The dispute raises federalism concerns as Vermont seeks financial support to address flooding and climate impacts, while critics warn the law may increase national energy prices and disrupt producers.
