The ensuing efforts were similar to the measures China had previously taken to ensure clear skies for the 2008 Summer Games in Beijing, but on a larger scale, the report notes. Tougher emissions standards were imposed on coal-fired plants and the number of cars on the road was curbed to cut vehicle emissions. Local officials were given environmental targets, and coal-fired boilers in homes were replaced with gas or electric heaters. The government’s reporting of air quality data also improved. Jia Pei, a 30-year-old Beijing resident who enjoys exercising outside, said the improved air quality puts him in a better mood. “In the past when there was smog, I would feel that I was inhaling dust into my mouth,” he said.
