Air pollution increases mortality rates, spreads disease, and impairs educational outcomes.
It also makes workers less productive, according to a study from researchers at the University of Singapore.
The Study, which monitored two textile factories in different cities in China, found that workers accomplished less when air pollution levels rose.
The authors of the Report spent a year reviewing how much fabric was being produced at the two factories, and then compared it to local data of air pollution. They found that the amount of fabric produced dropped when air pollution levels remained high for days on end.
The overall impact was a roughly 1% decline in productivity. That may not seem like a lot, but for companies of scale, a single percentage point can be a significant drop in revenue.
