World Asthma Day reminds us at the AIRE team why we care about clean air. Air pollution is a trigger for asthma. According to the 2017 HEI State of Global Air report, most people on Earth are living with PM2.5 concentrations which the US EPA has labeled as “Unhealthy for Sensitive Groups,” which includes people with asthma. Air Quality has improved enormously in the US, to the benefit of asthmatics and everyone else, since the passing of the Clean Air Act of 1970. The improvements in US air quality are even visible from space. However, India, China, UK, and other nations worldwide are currently facing air quality crises. Cleaning up the air in order to protect public health, while at the same time meeting climate goals, will require a combination of technical insight, policy innovation, and political will.
