States Propose New Indirect Source Rules Targeting Warehouse Emissions
A growing number of states are advancing indirect source rules (ISRs), making warehouse and related logistics operations responsible for reducing or offsetting air pollution from the vehicles that transport goods to and from the covered warehouses. California’s South Coast Air Quality Management District (SCAQMD) has already adopted Rule 2305 — affecting warehouses in the Los Angeles region — and new legislative and regulatory proposals may soon expand similar obligations statewide in California and to other jurisdictions. These measures aim to address pollution from mobile sources, such as trucks that frequent warehouse hubs indirectly, and require a suite of costly measures aimed at transitioning fleets away from diesel fuels and internal combustion engines. Although these proposals directly regulate warehouse owners and operators, they aim to transition fleets to alternative energy sources by imposing costs for warehouse visits.
