Improving US air quality, equitably
Study finds climate policy alone cannot meaningfully reduce racial/economic disparities in air pollution exposure. Decarbonization of national economies will be key to achieving global #netzero emissions by 2050, a major stepping stone to the Paris Agreement’s long-term goal of keeping global warming well below 2 degrees Celsius (and ideally 1.5 C), and thereby averting the worst consequences of climate change. Toward that end, the United States has pledged to reduce its #greenhousegasemissions by 50-52 percent from 2005 levels by 2030, backed by its implementation of the 2022 Inflation Reduction Act. This strategy is consistent with a 50-percent reduction in carbon dioxide (CO2) by the end of the decade. If U.S. federal #carbonpolicy is successful, the nation’s overall #airquality will also improve. Cutting #CO2emissions reduces atmospheric concentrations of air pollutants that lead to the formation of fine particulate matter (PM2.5), which causes more than 200,000 prema...
