An article written by two Jones Walker associates, Lucas Self and Hank Rauschenberger, was recently published in the ABI Journal, the monthly publication of the American Bankruptcy Institute. The article, “When Is an Environmental Claim Not an Environmental Claim: Climate-Change Claims in Bankruptcy Courts,” analyzes the case In re Peabody Energy Corp., where Peabody Energy Corporation (PEC) filed bankruptcy and was later sued by three California municipalities on claims of PEC’s coal sales increasing the amount of carbon dioxide in the atmosphere. Lucas and Hank explain the ruling of the case and how the decision will affect the rising number of climate-change claims.
