Perpetual Haze
During the three decades since Deng set China on a course toward market-style growth, rapid industrialization and urbanization have lifted hundreds of millions of Chinese out of poverty and made the country the world’s largest producer of consumer goods. But there is little question that growth came at the expense of the country’s air, land and water, much of it already degraded by decades of Stalinist economic planning that emphasized the development of heavy industries in urban areas.
For air quality, a major culprit is coal, on which China relies for about two-thirds of its energy needs. It has abundant supplies of coal and already burns more of it than the United States, Europe and Japan combined. But even many of its newest coal-fired power plants and industrial furnaces operate inefficiently and use pollution controls considered inadequate in the West.
Expanding car ownership, heavy traffic and low-grade gasoline have made autos the leading source of air pollution in major Chinese cities. Only 1 percent of China’s urban population of 560 million now breathes air considered safe by the European Union, according to a World Bank study of Chinese pollution published this year. One major pollutant contributing to China’s bad air is particulate matter, which includes concentrations of fine dust, soot and aerosol particles less than 10 microns in diameter (known as PM 10).
The level of such particulates is measured in micrograms per cubic meter of air. The European Union stipulates that any reading above 40 micrograms is unsafe. The United States allows 50. In 2006, Beijing’s average PM 10 level was 141, according to the Chinese National Bureau of Statistics. Only Cairo, among world capitals, had worse air quality as measured by particulates, according to the World Bank.
Emissions of sulfur dioxide from coal and fuel oil, which can cause respiratory and cardiovascular diseases as well as acid rain, are increasing even faster than China’s economic growth. In 2005, China became the leading source of sulfur dioxide pollution globally, the State Environmental Protection Administration, or SEPA, reported last year.
Other major air pollutants, including ozone, an important component of smog, and smaller particulate matter, called PM 2.5, emitted when gasoline is burned, are not widely monitored in China. Medical experts in China and in the West have argued that PM 2.5 causes more chronic diseases of the lung and heart than the more widely watched PM 10.
Perhaps an even more acute challenge is water. China has only one-fifth as much water per capita as the United States. But while southern China is relatively wet, the north, home to about half of China’s population, is an immense, parched region that now threatens to become the world’s biggest desert.
Farmers in the north once used shovels to dig their wells. Now, many aquifers have been so depleted that some wells in Beijing and Hebei must extend more than half a mile before they reach fresh water. Industry and agriculture use nearly all of the flow of the Yellow River, before it reaches the Bohai Sea.
In response, Chinese leaders have undertaken one of the most ambitious engineering projects in world history, a $60 billion network of canals, rivers and lakes to transport water from the flood-prone Yangtze River to the silt-choked Yellow River. But that effort, if successful, will still leave the north chronically thirsty.
This scarcity has not yet created a culture of conservation. Water remains inexpensive by global standards, and Chinese industry uses 4 to 10 times more water per unit of production than the average in industrialized nations, according to the World Bank.
In many parts of China, factories and farms dump waste into surface water with few repercussions. China’s environmental monitors say that one-third of all river water, and vast sections of China’s great lakes, the Tai, Chao and Dianchi, have water rated Grade V, the most degraded level, rendering it unfit for industrial or agricultural use.
Grim Statistics
The toll this pollution has taken on human health remains a delicate topic in China. The leadership has banned publication of data on the subject for fear of inciting social unrest, said scholars involved in the research. But the results of some research provide alarming evidence that the environment has become one of the biggest causes of death.
An internal, unpublicized report by the Chinese Academy of Environmental Planning in 2003 estimated that 300,000 people die each year from ambient air pollution, mostly of heart disease and lung cancer. An additional 110,000 deaths could be attributed to indoor air pollution caused by poorly ventilated coal and wood stoves or toxic fumes from shoddy construction materials, said a person involved in that study.
Another report, prepared in 2005 by Chinese environmental experts, estimated that annual premature deaths attributable to outdoor air pollution were likely to reach 380,000 in 2010 and 550,000 in 2020.
This spring, a World Bank study done with SEPA, the national environmental agency, concluded that outdoor air pollution was already causing 350,000 to 400,000 premature deaths a year. Indoor pollution contributed to the deaths of an additional 300,000 people, while 60,000 died from diarrhea, bladder and stomach cancer and other diseases that can be caused by water-borne pollution.
China’s environmental agency insisted that the health statistics be removed from the published version of the report, citing the possible impact on “social stability,” World Bank officials said.
But other international organizations with access to Chinese data have published similar results. For example, the World Health Organization found that China suffered more deaths from water-related pollutants and fewer from bad air, but agreed with the World Bank that the total death toll had reached 750,000 a year. In comparison, 4,700 people died last year in China’s notoriously unsafe mines, and 89,000 people were killed in road accidents, the highest number of automobile-related deaths in the world. The Ministry of Health estimates that cigarette smoking takes a million Chinese lives each year.
Studies of Chinese environmental health mostly use statistical models developed in the United States and Europe and apply them to China, which has done little long-term research on the matter domestically. The results are more like plausible suppositions than conclusive findings.
But Chinese experts say that, if anything, the Western models probably understate the problems.
“China’s pollution is worse, the density of its population is greater and people do not protect themselves as well,” said Jin Yinlong, the director general of the Institute for Environmental Health and Related Product Safety in Beijing. “So the studies are not definitive. My assumption is that they will turn out to be conservative.”
Growth Run Amok
As gloomy as China’s pollution picture looks today, it is set to get significantly worse, because China has come to rely mainly on energy-intensive heavy industry and urbanization to fuel economic growth. In 2000, a team of economists and energy specialists at the Development Research Center, part of the State Council, set out to gauge how much energy China would need over the ensuing 20 years to achieve the leadership’s goal of quadrupling the size of the economy.
They based their projections on China’s experience during the first 20 years of economic reform, from 1980 to 2000. In that period, China relied mainly on light industry and small-scale private enterprise to spur growth. It made big improvements in energy efficiency even as the economy expanded rapidly. Gross domestic product quadrupled, while energy use only doubled.
The team projected that such efficiency gains would probably continue. But the experts also offered what they called a worst-case situation in which the most energy-hungry parts of the economy grew faster and efficiency gains fell short.
That worst-case situation now looks wildly optimistic. Last year, China burned the energy equivalent of 2.7 billion tons of coal, three-quarters of what the experts had said would be the maximum required in 2020. To put it another way, China now seems likely to need as much energy in 2010 as it thought it would need in 2020 under the most pessimistic assumptions.
“No one really knew what was driving the economy, which is why the predictions were so wrong,” said Yang Fuqiang, a former Chinese energy planner who is now the chief China representative of the Energy Foundation, an American group that supports energy-related research. “What I fear is that the trend is now basically irreversible.”
The ravenous appetite for fossil fuels traces partly to an economic stimulus program in 1997. The leadership, worried that China’s economy would fall into a steep recession as its East Asian neighbors had, provided generous state financing and tax incentives to support industrialization on a grand scale.
It worked well, possibly too well. In 1996, China and the United States each accounted for 13 percent of global steel production. By 2005, the United States share had dropped to 8 percent, while China’s share had risen to 35 percent, according to a study by Daniel H. Rosen and Trevor Houser of China Strategic Advisory, a group that analyzes the Chinese economy.
Similarly, China now makes half of the world’s cement and flat glass, and about a third of its aluminum. In 2006, China overtook Japan as the second-largest producer of cars and trucks after the United States.
Its energy needs are compounded because even some of its newest heavy industry plants do not operate as efficiently, or control pollution as effectively, as factories in other parts of the world, a recent World Bank report said.
Chinese steel makers, on average, use one-fifth more energy per ton than the international average. Cement manufacturers need 45 percent more power, and ethylene producers need 70 percent more than producers elsewhere, the World Bank says.
China’s aluminum industry alone consumes as much energy as the country’s commercial sector — all the hotels, restaurants, banks and shopping malls combined, Mr. Rosen and Mr. Houser reported.
Moreover, the boom is not limited to heavy industry. Each year for the past few years, China has built about 7.5 billion square feet of commercial and residential space, more than the combined floor space of all the malls and strip malls in the United States, according to data collected by the United States Energy Information Administration.
Chinese buildings rarely have thermal insulation. They require, on average, twice as much energy to heat and cool as those in similar climates in the United States and Europe, according to the World Bank. A vast majority of new buildings — 95 percent, the bank says — do not meet China’s own codes for energy efficiency.
All these new buildings require China to build power plants, which it has been doing prodigiously. In 2005 alone, China added 66 gigawatts of electricity to its power grid, about as much power as Britain generates in a year. Last year, it added an additional 102 gigawatts, as much as France.
That increase has come almost entirely from small- and medium-size coal-fired power plants that were built quickly and inexpensively. Only a few of them use modern, combined-cycle turbines, which increase efficiency, said Noureddine Berrah, an energy expert at the World Bank. He said Beijing had so far declined to use the most advanced type of combined-cycle turbines despite having completed a successful pilot project nearly a decade ago.
While over the long term, combined-cycle plants save money and reduce pollution, Mr. Berrah said, they cost more — and take longer — to build. For that reason, he said, central and provincial government officials prefer older technology.
“China is making decisions today that will affect its energy use for the next 30 or 40 years,” he said. “Unfortunately, in some parts of the government the thinking is much more shortsighted.”
The Politics of Pollution
Since Hu Jintao became the Communist Party chief in 2002 and Wen Jiabao became prime minister the next spring, China’s leadership has struck consistent themes. The economy must grow at a more sustainable, less bubbly pace. Environmental abuse has reached intolerable levels. Officials who ignore these principles will be called to account.
Five years later, it seems clear that these senior leaders are either too timid to enforce their orders, or the fast-growth political culture they preside over is too entrenched to heed them.
In the second quarter of this year, the economy expanded at a neck-snapping pace of 11.9 percent, its fastest in a decade. State-driven investment projects, state-backed heavy industry and a thriving export sector led the way. China burned 18 percent more coal than it did the year before.
China’s authoritarian system has repeatedly proved its ability to suppress political threats to Communist Party rule. But its failure to realize its avowed goals of balancing economic growth and environmental protection is a sign that the country’s environmental problems are at least partly systemic, many experts and some government officials say. China cannot go green, in other words, without political change
In their efforts to free China of its socialist shackles in the 1980s and early 90s, Deng and his supporters gave lower-level officials the leeway, and the obligation, to increase economic growth.
Local party bosses gained broad powers over state bank lending, taxes, regulation and land use. In return, the party leadership graded them, first and foremost, on how much they expanded the economy in their domains.
To judge by its original goals — stimulating the economy, creating jobs and keeping the Communist Party in power — the system Deng put in place has few equals. But his approach eroded Beijing’s ability to fine-tune the economy. Today, a culture of collusion between government and business has made all but the most pro-growth government policies hard to enforce.
“The main reason behind the continued deterioration of the environment is a mistaken view of what counts as political achievement,” said Pan Yue, the deputy minister of the State Environmental Protection Administration. “The crazy expansion of high-polluting, high-energy industries has spawned special interests. Protected by local governments, some businesses treat the natural resources that belong to all the people as their own private property.”
Mr. Hu has tried to change the system. In an internal address in 2004, he endorsed “comprehensive environmental and economic accounting” — otherwise known as “Green G.D.P.” He said the “pioneering endeavor” would produce a new performance test for government and party officials that better reflected the leadership’s environmental priorities.
The Green G.D.P. team sought to calculate the yearly damage to the environment and human health in each province. Their first report, released last year, estimated that pollution in 2004 cost just over 3 percent of the gross domestic product, meaning that the pollution-adjusted growth rate that year would drop to about 7 percent from 10 percent. Officials said at the time that their formula used low estimates of environmental damage to health and did not assess the impact on China’s ecology. They would produce a more decisive formula, they said, the next year.
That did not happen. Mr. Hu’s plan died amid intense squabbling, people involved in the effort said. The Green G.D.P. group’s second report, originally scheduled for release in March, never materialized.
The official explanation was that the science behind the green index was immature. Wang Jinnan, the leading academic researcher on the Green G.D.P. team, said provincial leaders killed the project. “Officials do not like to be lined up and told how they are not meeting the leadership’s goals,” he said. “They found it difficult to accept this.”
Conflicting Pressures
Despite the demise of Green G.D.P., party leaders insist that they intend to restrain runaway energy use and emissions. The government last year mandated that the country use 20 percent less energy to achieve the same level of economic activity in 2010 compared with 2005. It also required that total emissions of mercury, sulfur dioxide and other pollutants decline by 10 percent in the same period.
The program is a domestic imperative. But it has also become China’s main response to growing international pressure to combat global warming. Chinese leaders reject mandatory emissions caps, and they say the energy efficiency plan will slow growth in carbon dioxide emissions.
Even with the heavy pressure, though, the efficiency goals have been hard to achieve. In the first full year since the targets were set, emissions increased. Energy use for every dollar of economic output fell but by much less than the 4 percent interim goal.
In a public relations sense, the party’s commitment to conservation seems steadfast. Mr. Hu shunned his usual coat and tie at a meeting of the Central Committee this summer. State news media said the temperature in the Great Hall of the People was set at a balmy 79 degrees Fahrenheit to save energy, and officials have encouraged others to set thermostats at the same level.
By other measures, though, the leadership has moved slowly to address environmental and energy concerns.
The government rarely uses market-oriented incentives to reduce pollution. Officials have rejected proposals to introduce surcharges on electricity and coal to reflect the true cost to the environment. The state still controls the price of fuel oil, including gasoline, subsidizing the cost of driving.
Energy and environmental officials have little influence in the bureaucracy. The environmental agency still has only about 200 full-time employees, compared with 18,000 at the Environmental Protection Agency in the United States.
China has no Energy Ministry. The Energy Bureau of the National Development and Reform Commission, the country’s central planning agency, has 100 full-time staff members. The Energy Department of the United States has 110,000 employees.
China does have an army of amateur regulators. Environmentalists expose pollution and press local government officials to enforce environmental laws. But private individuals and nongovernment organizations cannot cross the line between advocacy and political agitation without risking arrest.
At least two leading environmental organizers have been prosecuted in recent weeks, and several others have received sharp warnings to tone down their criticism of local officials. One reason the authorities have cited: the need for social stability before the 2008 Olympics, once viewed as an opportunity for China to improve the environment.
