Researchers at the George Washington University (GW) have identified that the number of federal and state climate lawsuits has been growing since 2006 in the most extensive study to date on the nature and impact of judicial resolutions of legal actions related to climate change. This first-of-a-kind analysis shows that air pollution and coal-fired power plants were the subject of the majority of the studied cases and 58 percent of all of the cases were won by litigants opposed to government regulation. The analysis also shows that pro-regulation plaintiffs won more than twice as frequently in cases involving renewable energy and energy efficiency.
