Leading U.S. insurers have nearly half-a-trillion dollars invested in fossil fuel energy and the electric and gas utility sectors, according to a recent report that urges state insurance regulators and board members of these companies to help move them out of such investments.

The winds continue to shift toward more regulation of insurance industry investments where it concerns climate change following transitions out of coal and other similar energies by European insurers and pushes by some state regulators to drive insurers away from investing in so-called “dirty energy.”
