This report summarizes responses from insurance companies to a survey on climate change risks developed by the National Association of Insurance Commissioners (NAIC). In 2013, insurance regulators in California, Connecticut, Minnesota, New York and Washington required insurers writing in excess of $100 million in direct written premiums, and licensed to operate in any of the five states, to disclose their climate-related risks using this survey. The aim of the survey, and Ceres’ analysis of the responses, is to provide regulators, insurers, investors and other stakeholders with substantive information about the risks insurers face from climate change and the steps insurers are taking—or are not taking—to respond to those risks. Because virtually every large insurer operates in at least one of the mandatory climate risk disclosure states, this analysis effectively opens a window into the entire industry. The report distills key findings and industry trends, and includes company specific scores based on disclosed actions taken to manage climate risks. It also offers recommendations for insurers and regulators to improve the insurance sectors’ overall management of climate change risks.
