The Cumulative Impacts Analysis Amendment Act of 2025 seeks to combat environmental injustices in low-income and predominantly Black neighborhoods in the District of Columbia by establishing a comprehensive cumulative impact statement process for permits related to environmentally harmful actions. This legislation requires a modified cumulative impact statement for District agency plans that may affect significant sources of environmental harm, emphasizing accountability through potential fines or revocation of actions for non-compliance. Additionally, it creates an Energy and Environmental Justice Division within the Department of Energy and Environment (DOEE) to focus on alleviating environmental burdens in these communities.

Key provisions of the bill include enhanced transparency and community engagement regarding cumulative impacts, with the possibility of denying proposed actions that disproportionately affect overburdened communities. The legislation updates definitions and requirements within the District of Columbia Environmental Policy Act of 1989, introducing terms such as "adverse cumulative stressors" and "overburdened community," while repealing outdated sections. Amendments also refine the terminology related to permits and certificates, mandate detailed assessments of neighborhood settings and facility operations, and prohibit funding for actions with identified disproportionate impacts unless approved by the Council. Overall, the bill aims to integrate environmental justice considerations into the District's planning and permitting processes.
