Environmental policies and problems in China

Environmental Policies and Problems in China: Air Pollution

From all appearances the economic success of China is secured, as China's economy is the fastest growing in the entire world however, unfortunately, China also has the highest annual incidence of early deaths stated to be attributed to air pollution. The National Geographic report entitled: "Chinese Air Pollution Deadliest in World" states that a World Health Organization (WHO) report "estimates that diseases triggered by indoor and outdoor pollution kills 656,000 Chinese citizens each year, and polluted drinking water kills another 95,600." (Holder, 2007) Pollutants which damage the air quality are inclusive of sulfur dioxide, particulate matter - a mixture of extremely small particles and water droplets- ozone, and nitrogen dioxide." (Holder, 2007) According to Holden's (2007) report: 'China accounts for roughly one-third of the global total for these pollutants..."

ATMOSPHERIC POLLUTION IN CHINA

The work of Juli S. Kim entitled: "A China Environment Health Project Fact Sheet: Transboundary Air Pollution - Will China Choke On Its Success?" relates difficulty in understating the affect of the atmospheric pollution of China on the Asia Pacific region and beyond." (Kim, 2007) The pollutants, including ozone, fine particulate matter, and mercury, are carried on prevailing winds:."..from continent to continent, and in this case, from Asia to North America." (Kim, 2007) According to Kim (2007) the motherload of the domestic and transboundary air pollution in China "originates from the country's heavy dependence on coal, which makes up about 70% of its energy mix. " Kim, 2007) Even in consideration of the efforts for diversification of energy sources it is expected that China's dependence upon coal will remain intact, at least "for the foreseeable future." (Kim, 2007) Because of China's dependence on coal as well as the very low quality of the coal, "the lack of widespread coal washing infrastructure and scrubbers at industrial facilities and power plants, and plans for building nearly 100 new coal-fired power stations each year until 2012 -..." (Kim, 2007) state that China faces increasing costs in terms of both health and problems relating to the environment in the East Asia/Pacific region and beyond." (Kim, 2007) China follows second only after the United States in consumption of energy and emission of greenhouse gas (GHG). China is additionally "expected to surpass the United States in GHG emissions by 2009." (Kim, 2007) Kim states the following negative economic and human health trends from China's Air Pollution:

The average decrease in China's crop yield attributable to the combined effects of acid rain from SO2 emissions and black carbon soot was 4.3% in the mid-1990s.

Climate experts link greenhouse gas emissions and deforestation to the rising incidences of natural disasters witnessed between January and September of 2006, which forced the evacuation and relocation of 13.2 million people and killed more than 2,300, causing direct economic losses of $24 billion.

According to recent estimates by Qin Dahe, director of the China Meteorological Administration, air pollution is driving some extreme weather events, which hamper China's economic growth by between 3 to 6% of GDP, or $70-130 billion, annually.

Coal burning in China emits 25% of global mercury and 12% of global CO2.

2006 SEPA survey found that 41% of fish species in water bodies in eastern Jiangsu Province, where there is a high concentration of manufacturers, contained various heavy metals transmitted through polluted air fall-out.

SEPA estimates that nearly 200 cities in China fall short of the WHO standards for airborne particulates. (Kim, 2007)

Kim states that desertification of China is taking place at an annual rate of 1,300 square miles resulting in destruction of farming lands and pushing rural individuals into the city. Cropland in China is further being destroyed by acid rain, which results from the combustion of coal and fossil fuel. Recent studies are reported to have examined the problem with black carbon (BC) soot in China. Black Carbon is the "active ingredient in haze produced by burning crop residues household coal stoves and vehicles - is potentially the second most potent global warming gas after CO2." (Kim, 2007) China emits more black carbon than any other country in the world. Black carbon particles are smaller than "one micron in diameter and cause hundreds of thousands of premature deaths from respiratory illnesses each year in China." (Kim, 2007) Even worse is the fact that black carbon blocks the light from the sun and results in lowering crop yields for both wheat and rice crops in China by approximately 30%.

II. AIR POLLUTION'S EFFECT ON HEALTH

Approximately 300,000 to 400,000 individuals die each year in China due to respiratory illnesses that air pollution triggers. Kim (2007) states that scientific researching is globally "illuminating the clear linkages between not only air pollution and respiratory complications, but also to heart disease. According to Kim a study published in the 'Heart' journal, which is among the largest studies ever which has focused on the links between heart diseases, stroke and air pollution is one that was conducted with a focus on women, state findings that air quality is "...a strong predictor of risks of stroke and heart diseases. While researchers are quite certain that fine particle air pollutants endanger health it is not understood in full yet whether "it is the chemical composition, size or ability to transport other pollutants deep into the lungs that is responsible for the effect." (Kim, 2007) Pollution is, according to the Chinese government's 'Green National Accounting Study Report', is cutting 3.1% of the GDP and some economists believe the real number is as high as 10%. (Kim, 2007; paraphrased)

III. INVISIBLE EXPORT OF CHINA

Kim (2007) relates that China has an invisible export and that the contribution of China to global warming and regional mercury fallout states indications that: "...53% of the world's natural and human caused mercury emissions come from Asia, while Africa is distant second with only 18%." There have been high levels of mercury deposition in the United States and research has shown that "...one-fifth of the mercury entering the Willamette River in Oregon comes from abroad, mostly from China." (Kim, 2007) Mercury in China is in its elemental form and therefore, insoluble however, "by the time it reaches the U.S. west coast, it has been transformed into a reactive gaseous material that dissolves in Oregon's web climate - falling onto the Willamette River's watershed and slowly building up toxic levels of mercury in the local wildlife." (Kim, 2007) Furthermore, the cement kilns in China, producing approximately 40% of the cement production annually and worldwide "are a major source of dioxin and furan - pollutants that can be transported airborne across long distances." (Kim, 2007)

IV. GOVERNMENT RESPONSE

The work of Alex Wang entitled: 'The Downside of Growth: Law, Policy and China's Environmental Crisis" relates that the Chinese government has "made a number of major policy pronouncements concerning the environment since the beginning of the reforms in 1978. In 1983, the government 'declared environmental protection a basic national policy.'" (Wang, nd) A broad plan for achieving sustainable development was made by China in 1994. The State Council, for the first time issued a "five-year plan on environmental protection." (Wang, nd) During this period the policy pronouncements stood as representation of the shift that had been made in China "...away from a single-minded focus on economic development to an approach that balances development and environmental protection." (Wang, nd) The problem has been one in which the opponents of environmental protection "were only assuaged by Communist party leadership's assurance that environmental protection would be phased in only to the extent that China's economy could handle. In practice, this has meant that enforcement of environmental regulations has been stronger in the most economically robust industries and regions, and weaker in areas with under-performing economic growth." (Wang, nd) While the environmental problems of China are critically serious, without the environmental reforms, China would certainly be in a worse predicament. In the past twenty years the energy consumption of China has been "only half that of its rate of economic growth..." (Wang, nd) This has been accomplished through a reduction in China's energy intensity by 50% since 1980. The following table lists the developments of China's installed power capacity and power generation in recent years.

V. SOLUTIONS AND RECOMMENDATIONS

The work entitled: "Energy Futures and Urban Air Pollution: Challenges for China and the United States" relates the GDP in the United States and the energy use per capita are both several times higher than those for China. These comparisons reflect the cumulative effects of an enormous range of historical activities that contributed to building the U.S. economy. China has embarked on the same path in just the last 25 years and, as economic development has run ahead of pollution control, already is experiencing the adverse health, agricultural, environmental and quality of life effects largely ameliorated in the U.S. In the last 30 years." (2007) Recommendations of this report include those as follows:

China should learn from the successes and failure of the U.S. And other developed countries in reducing the influence of energy use on air quality;

Continued dialogue and information exchange among U.S. And Chinese scientists and policy-makers should be promoted through professional organization, government support programs, and the National Academies in both countries to promote joint development of energy and pollution control strategies." (Committee on Energy Futures and Air Pollution in Urban China and the United State, Policy and Global Affairs, 2007)

Other findings of this report include the fact that "an important lesson learned is that air pollution damage imposes major economic costs, through premature mortality, increased sickness and lost productivity, as well as in decreased crops yields and economic impacts." (Committee on Energy Futures and Air Pollution in Urban China and the United State, Policy and Global Affairs, 2007) Studies conducted in the United States have shown that "emission reduction programs provide much greater benefit than their costs." (Committee on Energy Futures and Air Pollution in Urban China and the United State, Policy and Global Affairs, 2007) It is interesting to note that emission controls are generally not as expensive as first believed to implement and "appropriate programs can lead to economically efficient approaches for improving the environment, reducing costs further." (Committee on Energy Futures and Air Pollution in Urban China and the United State, Policy and Global Affairs, 2007) It is stated that "control costs are not purely costs as they create opportunities..." such as the manufacture and sales of energy efficient pollution control equipment. Air pollution industries in the U.S. is said to have generated an additional $27 billion in revenues employment approximately 178,000 in 2001. (Committee on Energy Futures and Air Pollution in Urban China and the United State, Policy and Global Affairs, 2007; paraphrased) Recommendations which arose from these findings include the recommendation that both the U.S. And China need to improve permitting policies and economic mechanisms that reflect the external costs of pollution that are being paid by others whether it be through adverse health effects and quality of life degradation and might include taxes high enough on emissions to make the adding of controls more attractive economically and rebates or subsidies are suggested as possible methods for encouraging higher efficiency as well as technologies of a renewable nature. (Committee on Energy Futures and Air Pollution in Urban China and the United State, Policy and Global Affairs, 2007)

This study further states findings that concentration for SO2 and NO2 along with Pb of an excessive nature have experienced reductions in order to comply with the levels of health standards in the United States however, China is lagging behind and there are still to many areas in China "where these exceed ambient standards." (Committee on Energy Futures and Air Pollution in Urban China and the United State, Policy and Global Affairs, 2007) Stated as recommendations are those as follows:

The U.S. And China should "adopt minimum standards based on healthful air quality, which may require revising currently accepted standards.

Greater efforts are needed to understand and educe emissions from local sources in China where these standards are exceeded. These efforts would include source apportionment and dispersion modeling studies to determine sour contributions, attainment studies to determine the need emissions reductions, engineering design studies to evaluate control alternatives, enforcements to assure that the controls are implemented, and monitoring at all emissions source and receptor to assure that the reductions are successful;

U.S. And China need to evaluate and redesign compliance monitoring networks to better understand these precursor gases and local vs. regional contributions to PM25 and O3;

Multiple complementary modeling and data analysis methods need to be applied in both countries to determine major contributors and to evaluate non-linearity in emission reduction efforts;

5) Regional emission caps currently in palace in both the U.S. And China should be reexamined as they may be insufficient to attain healthful ambient concentrations; and PM25 control should be emphasized over, but not at the expense of PM10 and O3 reductions.
