China clears smog to raise life expectancy
China could raise average life expectancy by 2.9 years if it improves air quality to levels recommended by the World Health Organisation (WHO), according a new study from a US research group, reports Reuters. China has vowed to determine the precise impact of air and water pollution on health as part of its efforts to raise average life expectancy to 79 years by 2030 from 76.3 years in 2015. According to the Energy Policy Institute (EPI) at the University of Chicago, big air quality improvements made in the last five years have already been enough to push up average lifespans. The University of Chicago says that while the world’s biggest polluter faces a long road to reach national and international air quality standards, the results “suggest the country is winning its war on pollution”. Based on daily data from more than 200 monitors across China from 2013 to 2017, the analysis found that cities have cut levels of PM 2.5 — the tiny airborne particles considered most harmful to health—by an average of 32 per cent in just four years. Another study published by it last year had found that air pollution in northern China had cut life expectancy by three years.
