SB 149 Maryland Senate · 2025 Regular Session

Climate Change Adaptation and Mitigation - Total Assessed Cost of Greenhouse Gas Emissions - Study and Reports

SB 149 establishes a program requiring fossil fuel extraction and petroleum refining businesses to pay into a dedicated Climate Change Adaptation and Mitigation Fund. The fund will finance projects to adapt to climate impacts (like coastal flooding and extreme weather) and address health effects on vulnerable populations, managed by the Department of the Environment. The bill mandates annual audits of the fund by the Legislative Auditor to ensure proper use of these revenues. This creates a new state revenue stream for climate action directly tied to fossil fuel industry payments.
