During the period of 1980-2000, the US obtained substantial reductions in air pollution and improvements in life expectancy (LE). Multiple factors contributed to improved health. This report explores and illustrates trade-offs between income, air pollution, and LE. Both improved air quality and income growth contributed to LE gains - without evidence of substantial negative tradeoffs between air pollution and income. Cleaner air may be considered an "economic good" with contributions to health, wellbeing, and human capital.
在1980年至2000年期间，美国在空气污染减排和预期寿命（LE）改善方面取得了显著成效。多种因素促成了健康状况的改善。本报告探讨并说明了收入、空气污染和预期寿命之间的权衡取舍。空气质量的改善和收入增长都对预期寿命的提高有所贡献——没有证据表明空气污染和收入之间存在重大的负面权衡。清洁空气可被视为一种“经济商品”，对健康、福祉和人力资本都有贡献。
