“The Air Quality Life Index, or AQLI, converts air pollution concentrations into their impact on life expectancy. From this, the public and policymakers alike can determine the benefits of air pollution policies in perhaps the most important measure that exists: longer lives. Produced by the Energy Policy Institute at the University of Chicago (EPIC), the AQLI is based on frontier research by EPIC’s director Michael Greenstone that quantified the causal relationship between human exposure to air pollution and reduced life expectancy. Combining this analysis with highly localized pollution measurements yields unprecedented insight into the true cost of air pollution in communities around the world. Through the interactive platform, users can learn not only how polluted their community is, but also how much longer they could live if their community complied with World Health Organization guidelines or national standards. It makes evident that policies that reduce fossil fuel use can allow people to live longer and healthier lives today, as well as reduce the risks of disruptive climate change.”
