Aon's sustainability report states that the company "is committed to helping clients and other stakeholders understand and manage their environmental, social and governance (ESG) risks." However, Aon's actions don't reflect this commitment. For example, Aon is a member of the U.S. Chamber of Commerce, which has fought climate action at every turn. Aon also funds the American Legislative Exchange Council (ALEC), a conservative lobbying group that has pushed for climate denial and attacks on renewable energy.
