Insurance Coverage for Environmental Claims: Current Litigation Issues in the United States

The insurance industry introduced exclusions for environmental claims in the general commercial litigation policies in the early 1970s, and introduced even greater restrictions in the 1980s. Litigation over the two most common pollution exclusions has been robust and will likely continue to increase. This article first briefly reviews the history of insurance coverage for environmental claims in the United States, including the most common issues and how the courts have addressed them. The article then discusses the current issues and emerging trends in insurance coverage for environmental claims under the general commercial policies. Finally, there is a brief discussion on the growing market for insurance products that specifically cover (rather than exclude) environmental claims.
