Environmental groups and some state regulators are urging the property and casualty insurance industry to push for initiatives to lessen the impact of climate change. The sector "is in a unique position to influence society in reducing risks," said Cynthia McHale of Ceres. Catastrophe losses "have become unsustainable," said Julie Rochman of the Insurance Institute for Businesses and Home Safety. "Way too many people are suffering irreparable damage ... way too many people are losing their lives. We have to do something."
