Mitigating Climate Change → Beneficial Impacts on Health
By responding to the need to reduce emissions, we create opportunities for a range of enormously beneficial health outcomes.
In the U.S., clean energy policies consistent with warming of 2°C could prevent 175,000 premature deaths by 2030, and subsequently 22,000 annually after 2030, with clean transportation contributing additional benefits.

Encouraging behavioral changes such as active travel (walking or bicycle riding), as well as reducing consumption of red and processed meat and increasing consumption of plant-based foods, leads to health benefits. Increasing median daily walking and bicycling from 4 to 22 minutes reduced the burden of cardiovascular disease and diabetes by 14%, and decreased greenhouse gas emissions (GHGE) by 14%. Low-carbon driving reduced GHGE by 33.5% and cardiorespiratory disease burden by less than 1%.

By adopting simple retrofits to school buses, thus reducing diesel emissions, school districts experienced a 33% drop in asthma and bronchitis cases and a 40% drop in cases of pneumonia among children. Program benefits are estimated to be between 7 and 16 times program costs.
