Courts - Global Warming and Climate Change - Prohibited Actions (Ratepayer Protection Act of 2025)

This bill, known as the Ratepayer Protection Act of 2025, prevents Maryland state and local governments from suing businesses for financial or economic damages caused by global warming or climate change. It achieves this by adding a new legal provision that explicitly bars government agencies from filing such lawsuits, while clarifying that the law does not stop governments from enforcing existing environmental, health, or zoning regulations. The legislation defines "business" broadly to include various entities and financial institutions, and it takes effect on October 1, 2025.
