Satellite data reveals Beijing as air pollution capital of world | News | The Guardian
As it gears up to host the 2008 Olympic Games Beijing has been awarded an unwelcome new accolade: the air pollution capital of the world.
Satellite data has revealed that the city is one of the worst environmental victims of China's spectacular economic growth, which has brought with it air pollution levels that are blamed for more than 400,000 premature deaths a year.
According to the European Space Agency, Beijing and its neighbouring north-east Chinese provinces have the planet's worst levels of nitrogen dioxide, which can cause fatal damage to the lungs.
An explosive increase in car ownership is blamed for a sharp rise in unhealthy emissions. In the past five years the number of vehicles clogging the capital's streets has more than doubled to nearly 2.5m. It is expected to top the 3m mark by the start of the Olympics in 2008.
Alarm about the perilous state of the environment has gathered pace in recent years. China is the world's second-largest producer of greenhouse gases, and the World Bank has warned it is home to 16 of the planet's 20 most air-polluted cities.
According to the European satellite data, pollutants in the sky over China have increased by about 50% during the past 10 years. Senior officials warn that worse is still to come. At a recent seminar Zhang Lijun, deputy director of the environmental protection agency, said that pollution levels could more than quadruple within 15 years unless the country can slow the rise in energy consumption and automobile use.
A recently published study, conducted by the Chinese Academy on Environmental Planning, blamed air pollution for 411,000 premature deaths - mostly from lung and heart-related diseases - in 2003. It said that a third of China's urban residents were exposed to harmful levels of pollution. More than 100 million people live in cities, such as Beijing, where the air is considered "very dangerous".
The political implications are also becoming more apparent. Health concerns, particularly regarding cancer and birth defects thought to be caused by chemical factories, have been a major factor in a recent wave of protests. Conservation groups say acid rain falls on a third of China's territory and 70% of rivers and lakes are so full of toxins they can no longer be used for drinking water.
