The $2-trillion global insurance industry has expressed concern about the immense prospective financial risks from natural disasters caused by global climate change. The insurance industry can take a reactive approach by limiting or withdrawing coverage, or it can take a proactive approach by encouraging actions to reduce greenhouse-gas emissions. Many energy-efficient technologies and associated indoor environmental quality strategies have the potential to both reduce emissions and reduce ordinary insured losses involving property, health, or liability. Such measures represent an attractive ”no-regrets” opportunity for the insurance industry, as the loss-prevention benefits would have distinct value irrespective of the timing or extent of damages related to global climate change.
