The pollution exclusion removes coverage for injury or damage caused by the release of pollutants. Modern absolute and total forms apply broadly to any solid, liquid, gaseous, or thermal irritant or contaminant, including smoke, fumes, chemicals, and waste.
Earlier qualified forms contained an exception for sudden and accidental releases, which produced decades of litigation over whether sudden carries a temporal meaning.

Why it Matters?
This exclusion is central to environmental, construction, habitability, and long-term care claims, and it reaches far beyond classic industrial contamination. Carbon monoxide, mold, cleaning chemicals, lead, and PFAS claims all draw pollution exclusion analysis, and the outcome frequently determines whether any coverage exists for a substantial exposure.
