Lower costs Climate action reduces risks — limiting extreme heat, lowering flood damages, protecting agricultural productivity, and easing long-term strain on drinking water supplies. These impacts already affect the region, driving infrastructure damage and higher public costs. Reducing emissions now limits the severity of extreme heat and related health impacts, reduces the likelihood and cost of major flood events, protects agricultural productivity, and lessens strain on drinking water. These avoided impacts save billions of dollars in infrastructure repairs, emergency responses, health costs, and lost economic activity.
