One of the serious negative consequences of China's rapid industrial development has been increased pollution and degradation of natural resources. China is widely expected to surpass the United States as the world's largest emitter of carbon dioxide and other greenhouse gases sometime in 2007 or 2008. A World Health Organization report on air quality in 272 cities worldwide concluded that seven of the world's 10 most polluted cities were in China. According to 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. Almost all of the nation's rivers are considered polluted to some degree, and half of the population lacks access to clean water. By some estimates, every day approximately 300 million residents drink contaminated water. Ninety percent of urban water bodies are severely polluted. Water scarcity also is an issue; for example, severe water scarcity in Northern China is a serious threat to sustained economic growth and the government has begun working on a project for a large-scale diversion of water from the Yangtze River to northern cities, including Beijing and Tianjin. Acid rain falls on 30% of the country. Various studies estimate pollution costs the Chinese economy 7%-10% of GDP each year.

The United States and China are members of the Asia Pacific Partnership on Clean Development and Climate (APP). The APP is a public-private partnership of six nations--Australia, China, India, Japan, the Republic of Korea, and the United States--committed to explore new mechanisms to meet national pollution reduction, energy security and climate change goals in ways that reduce poverty and promote economic development. APP members have undertaken cooperative activities involving deployment of clean technology in partner countries in eight areas: cleaner fossil energy, renewable energy and distributed generation, power generation and transmission, steel, aluminum, cement, coal mining, and buildings and appliances.

The United States and China have been engaged in an active program of bilateral environmental cooperation since the mid-1990s, with an emphasis on clean energy technology and the design of effective environmental policy. While both governments view this cooperation positively, China has often compared the U.S. program, which lacks a foreign assistance component, with those of Japan and several European Union (EU) countries that include generous levels of aid.
