Assessing the Costs and Benefits of Mandatory Climate Risk Disclosure

Climate impacts are already threatening major economic sectors in novel ways and could cost the global economy trillions of dollars annually by 2100.

With trade groups expected to challenge any new disclosure requirement by claiming that its costs exceed its benefits, defending the rule’s economic analysis will be crucial in court.
