Among many lawsuits and enforcement actions, the Department of Justice (DOJ) secured an agreement to address the Jackson, Mississippi water crisis and sued to limit air emissions at a facility in Louisiana. And there’s a growing trend toward environmental justice litigation over air quality impacts from warehouses.

In 2023, community groups sued local governments and state agencies on environmental justice grounds. On Aug. 21, 2023, three environmental groups in Colorado—GreenLatinos, 350 Colorado, and Earthworks—filed a lawsuit in Denver County District Court against the Colorado Air Quality Control Commission to broaden the scope of the state’s recently finalized environmental justice rules. According to the lawsuit, the state’s environmental justice rules fail to ensure that residents of communities who “have long borne a disproportionate share of adverse human and environmental effects from polluting industries” receive the protections provided by the state’s recent Environmental Justice Act.
