Since May 2009, this treaty also covers polybrominated diphenyl ethers and Perfluorooctanesulfonic acid. Perfluorinated compounds are associated with altered thyroid function and decreased sperm count in humans. It is a big challenge for China to control and eliminate POPs, since they often are cheaper than their alternatives, or they are unintentionally produced and then simply released into the environment to save on treatment costs.

China has achieved some improvements in environmental protection during the recent years. According to the World Bank, 'China is one of a few countries in the world that have been rapidly increasing their forest cover. It is managing to reduce air and water pollution.'

As part of US $498 billion economic stimulus package of November 2008 (the largest in China's history), the government plans to enhance sewage and rubbish treatment facilities and prevent water pollution, accelerate green belt and natural forest planting programs, and increase energy conservation initiatives and pollution control projects.

Climate change in China

China is the largest emitter of greenhouse gases, ahead of the United States of America. In 2008, China contributed 22% of global emissions, followed by the US with 20% of emissions. As China rapidly industrialized, especially in its heavy industries, it created an overwhelming demand on the world’s energy supplies and raised environmental concerns. Hence, China needs to find less resource-intensive paths to growth. This issue can be viewed from three different perspectives: the Chinese government, the producers, and the consumers.
At the macro level, the government wants to pursue economic goals which are to be traded off environmentally. China is still at the stage of development where massive investments go to heavy industries. Heavy industries promoted in the first five-year plan still enjoy tremendous privileges. Such industries impact the environment adversely. At the micro level, to maximize profits, firms use coal, which is the cheapest yet dirtiest form of energy supply. Furthermore, with high economic growth, consumers pursue an affluent lifestyle leading to intensive energy usage. This exacerbates climate change problems.

Impact of Climate Change in China

The implications of climate change, indubitably, impose serious setbacks on global health and will hinder the economic development of various regions worldwide impacting countries on more than just the basic environmental scale. As in the case of China, we will see the effects on a social and economic level.

China’s first National Assessment of Global Climate Change, released recently by the Ministry of Science and Technology (MOST), states that China already suffers from the environmental impacts of climate change: increase of surface and ocean temperature, rise of sea level. Rising sea level is an alarming trend because China has a very long and densely populated coastline, with some of the most economically developed cities such as Shanghai, Tianjin, and Guangzhou situated there. Chinese research has estimated that a one-meter rise in sea level would inundate 92,000 square kilometres of China’s coast, thereby displacing 67 million.

There has also been an increased occurrence of climate-related disasters such as drought and flood and the amplitude is growing. They have grave consequences for productivity when they occur, and also create serious repercussions for natural environment and infrastructure. This threatens the lives of billions and aggravates poverty.

Furthermore, climate change will worsen the uneven distribution of water resources in China. Outstanding rises in temperature would exacerbate evapo-transpiration intensifying the risk of water shortage for agricultural production in the North. While because of the southern region’s over abundance in rainfall, most of its water is lost due to flooding. As the Chinese government faces challenges managing its expanding population, an increased demand for water to support the nation’s economic activity and people will burden the government. In essence, a water shortage is indeed a large concern for the country.

Lastly, climate change could endanger human health by increasing outbreaks of disease and their transmission. After floods, for example, infectious diseases such as diarrhea, cholera are all far more prevalent. These effects would exacerbate the degradation of the ecologically fragile areas in which poor communities are concentrated pushing thousands back into poverty.

Protection of forests and control of desertification

 or naturally regrown woods. 12% of China's land area, or more than 111 million hectares, is closed forest. However, the UNEP also estimates that 36% of China's closed forests are facing pressure from high population densities, making preservation efforts that much more crucial. In 2011, Conservation International listed the forests of south-west Sichuan as one of the world's ten most threatened forest regionshttp://pulitzercenter.org/projects/china-deforestation-tourism-united-nations-international-year-forests

Plastic bag reduction efforts

Beginning on June 1, 2008, for the entire country of China, all supermarkets, department stores and shops are prohibited from giving out free plastic bags. Stores must clearly mark the price of plastic shopping bags and are banned from adding that price onto the price of products. The production, sale and use of ultra-thin plastic bags - those less than 0.025 millimeters, or 0.00098 inches, thick - are also banned. The State Council calls for "a return to cloth bags and shopping baskets." This ban, however, does not include the widespread use of cardboard shopping bags at clothing stores or the use of plastic bags at restaurants for takeout food. Since the ban, there has been ten percent fewer plastic bags thrown away.
