校车的柴油排放使儿童暴露在高度的空气污染中;改装公交车发动机可以大大减少这种暴露。使用从整个格鲁吉亚2656改造的变化，我们估计减排对区级健康和学业成绩的影响。我们展示了对呼吸健康的积极影响，通过全州范围内的有氧能力测试来衡量。对体重指数的安慰剂试验显示没有影响。我们还发现，改造区的经验显着的英语测试成绩的收益和较小的收益在math. Our研究结果表明，发动机改造可以有意义和成本效益的影响健康和认知功能。
Diesel emissions from school buses expose children to high levels of air pollution; retrofitting bus engines can substantially reduce this exposure. Using variation from 2656 retrofits across Georgia, we estimate effects of emissions reductions on district-level health and academic achievement. We demonstrate positive effects on respiratory health, measured by a statewide test of aerobic capacity. Placebo tests on body mass index show no impact. We also find that retrofitting districts experience significant test score gains in English and smaller gains in math. Our results suggest that engine retrofits can have meaningful and cost-effective impacts on health and cognitive functioning.
