The board of Aviva Plc, one of the world's largest insurers, must review its climate risk exposures and evaluate next steps. Risk experts at the firm have conducted a robust set of analyses prepared for its regulator, the Bank of England, simulating how various climate scenarios could impact the business. Against this uncertain future-and given their history of leadership in sustainability, the board and CEO Amanda Blanc will review options for Aviva Plc to address this business and societal challenge, ranging from dealing with flood risk to working to effect large scale systems change.
