Second, they found that while much of the air pollution policies have focused to date on the electricity sector, damages from farms are now larger than those from utilities. Indeed, farms have become the largest contributor to air pollution damages from PM2.5 related emissions. —Tschofen et al. Peter Tschofen, Inês L.
