CONSEQUENSES OF THE SMOG IN CHINA The economic burden of premature mortality and morbidity associated with air pollution was estimated to be 157.3 billion Yuan in 2003. Over 30 billion Yuan in damages to crops. Increase Chinese emgration : 60% (2011) – 64% (2013).

Industrial production and coal burning are responsible for 25% and 18 % of Beijing’s PM2.5 . CAUSES OF SMOG Source: http :// www.pollutionpollution.com/2014/03 / how-to-control-industrial-pollution.html Research by the Chinese Academy of Science found that industrial pollution is the biggest source of PM2.5 problems, which cause Beijing’s smog .
Source: http :// www.dailymail.co.uk/news/article-469041/Beijing-shrouded-cloud- -pollution.html CAUSES OF SMOG A ir pollution in China’s megacities have shifted from coal-burning only to a mix ofcoal burning and vehicle emissions. Pollutants from vehicles contribute to more than 22.5 % of PM2.5 in Beijing.
F ireworks increased the level of PM2.5 by 80 times during the traditional Chinese New Year in 2012. Crop stubble burning is a method used frequently by farmers to deal with agricultural waste. CAUSES OF SMOG
TACKLING THE SMOG Policy Changes in London after the Smog . In 1952, coal supplied 61 % of London’s energy needs, and 28% was for household use alone. The household use of coal started to decline in 1957. From 1950 to 2000, the annual average smoke and SO2 concentrations in London were reduced by 95% and 98% respectively .

TACKLING THE SMOG China’s Way to Clean Air The gap between Legislation and Implementation The targets set for Beijing’s annual average concentration in the Action Plan are conservative. Furthermore, targets for the annual average PM2.5 concentration in cities in the three key regions, except Beijing, are unclear, as they require percentage reductions in PM2.5 based on a base year . The annual average concentration of PM2.5 in those cities in the base year (2012) has not been reported and may not even exist because PM2.5 was only widely monitored and assessed in China since 2013.
TACKLING THE SMOG Public Awareness 26 % increase of the number of total environmental tips received on 12369 from 2012 to 2013, more than 70% of the tips concerned airborne pollution in 2013 .
DISCUSSION AND RECOMMENDATIONS China’s air pollution problem is no worse than London’s great smog in 1952 and Japan’s smog of the 1960s . China overtook the US as the biggest source of greenhouse gases in 2006 and has put the globe on a path to exceed UN targets for the rise in the Earth’s temperature. With similar causes of air pollution such as coal burning, vehicle emissions, China can certainly learn from London’s experience in the 1950s in tackling the smog problem. However, there are also differences in the scale of the events the lessons learned from London may not be well suited for China .
