Lessons to learn from China improved air quality in record time.
For over four decades, China’s economy has maintained rapid growth hence captured worldwide attention with its achievements. However, the pollution that comes with it, particularly that of the air, has also attracted global attention and condemnation in equal measure.
So then as the World Celebrate the World envionment Day in China what lessons can be drawn from Chinese improved air quaity?
Smog was once a synonym for China, and it seriously threatened people’s health, their daily lives and work. However,things have changed dramatically over the past five years.
In 2013, the average number of smog days reached its highest record in China in 52 years, and its impact extended to every socio-economic aspect. Calls to tackle smog were accumulating and gain momentum.
Last year, the proportion of average “good air” days in 338 prefecture-level cities across the country reached 79.3 percent, and people have found that need to wear facial masks less often.
looking back on history, it took Los Angeles and London more than 50 years to tackle their air pollution problems.
Unlike those two cities, China’s air pollution was more complicated and compounded by rapindly industrialized economy and factories and were producing gases.In addition to varying regional climates and environments, so the challenge to control smog was more significant.
Nonetheless, China achieved emission-reduction results in record time, that developed Western countries had taken decades to attain.
How did China manage to improve its air quality in such a short time？
Smog control needs to be preceded by relevant legislation. In 2012, China issued new air quality standards. It was the first time that the national air quality standard included levels of PM2.5 concentration. In the next year, China issued an action plan for air pollution control.
The country also improved its laws, regulations and emission standards, while introducing new ones preventing and controlling air pollution and providing critical support for smog control.
The key to smog control and air-quality improvement lies in eliminating the root causes and scientifically understanding what and how air pollutants are formed so that they may be prevented and controlled.
China is resorting to technology to tackle smog. With specialized tools, scientists can measure pollutants in different areas and see how the formation is different, thus taking more targeted measures.
The achievements have been remarkable. But if China wants to further significantly reduce the concentration of PM2.5 and strives to increase the proportion of average “good air” days to surpass 80 percent, it needs to continue its race of winning the battle for blue skies.
This success is on the reason china was seected to host the current World environment Day Celebration. we Solute the Chinese authorities and we hope emerging economies like Nigria, Philipine, Turkey and Mexico even India can benchmark and have alearning experience from china.
