"In 2008, China surpassed the United States as the largest global emitter of greenhouse gases by volume. The increase in China's emissions is primarily due to the country's reliance on coal, which accounts for over two-thirds of its energy consumption. It contributes to sulfur dioxide emissions causing acid rain, which falls on over 30 percent of the country. According to the People's Republic of China's own evaluation, two-thirds of the 338 cities for which air-quality data are available are considered polluted— two-thirds of them moderately or severely so. Respiratory and heart diseases related to air pollution are the leading cause of death in China."
