China’s environment: An economic death sentence by Minxin Pei @FortuneMagazine January 28, 2013, 2:48 PM EDT E-mail Tweet Facebook Google Plus Linkedin Share icons FORTUNE — For a long time, environmental activists, economists, and China scholars have warned about the coming environmental disaster in China. Such a catastrophe finally appeared in the most dramatic form in mid-January, when a thick layer of poisonous pollutants smothered much of northern China and made air in Beijing hazardous to breathe. For the Chinese government, this was merely one of many wake-up calls. The question on everyone’s mind is whether Beijing will finally muster the political will to implement policies to avert an ecological calamity that will almost certainly spell the end of the Chinese economic miracle and potentially lead to the fall of the Communist Party itself. Judging by the numbers, the scope of China’s environmental degradation is beyond shocking. Consider: The World Bank estimated, in a 2007 report, that pollution caused 5.8% of China’s GDP in premature deaths, health care costs, and material damages. Air pollution alone is estimated to kill 700,000 people a year. A 2012 MIT study estimated that air pollution in 2005 cost the Chinese economy $112 billion in lost labor and healthcare costs, roughly five times higher than it was in 1975. In 2010, airborne microscopic pollutants caused an estimated 8,600 premature deaths in four major Chinese cities: Beijing, Shanghai, Guangzhou, and Xian. According to a Chinese vice minister of environmental protection, the water quality in five of the nine bays along China’s coast was “extremely poor.” Results from monitoring stations along 10 major river basins show that 40% of the water is polluted. And 55% of the underground water in 200 cities is polluted. On top of that, about 300 million rural residents do not have access to safe drinking water. Soil pollution is endangering China’s food chain. Roughly 10% of the country’s arable land has been contaminated by heavy metal, based on scientific studies conducted in the late 1990s. In 2006, the Chinese government began a nationwide survey of soil pollution. However, it has not released the results, most probably because the findings are too alarming for the government to release.

Nevertheless, the Chinese government can take a comprehensive approach to environmental protection by adopting tougher environmental standards, changing their economic policy, increasing investment in the environment, and mobilizing the press and civil society to take part in these efforts. Retrofitting the country’s coal-fired power plants with modern pollution control technology should cut down the emission of harmful particulates significantly. Adopting a higher clean-fuel standard for cars and other vehicles, which now contribute to the bulk of urban pollution, will almost certainly make a difference. Gasoline and diesel used in Chinese have much higher sulfur content than the fuel used in the West. And if authorities in China took enforcement of existing environmental regulations more seriously, they could also make a huge impact, as local authorities and Chinese companies routinely violate such rules to cut costs. China also needs to shift its economy away from energy-intensive sectors, like the country’s fast-growing, mammoth steel industry, and toward more energy-efficient, high-tech, and service industries. Today, China produces 720 million tons of steel a year (46% of the world’s total), consuming hundreds of millions of tons of coal and discharging massive quantities of pollutants in the process. Another example is China’s automobile industry. After years of spectacular growth, China now has the world’s second-largest automobile sector (after the United States). The number of motor vehicles on Chinese roads is close to 230 million (including 110 million passenger cars). A slimming-down of these high-energy industries will likely yield another measurable improvement in China’s environment. Of course, China will bear significant transition costs with factory closures and job losses in these industries, but such restructuring can help expand labor-intensive and greener sectors, such as health care, tourism, and professional services. China also needs to step up its investment in its environment. At the moment, China spends $91 billion a year, or 1.3% of GDP, on environmental protection. This is far from adequate. To remedy the consequences of past under-investment, experts believe China needs to spend 2-4% of GDP on its environment. Unfortunately, these policy improvements — strict enforcement of environmental standards, a shift in industrial policy, and an increase in environmental spending — will not make a fundamental difference unless and until the Chinese government becomes more forthcoming and transparent and allows the media and civil society to play a far more active role in environmental stewardship. A sad and well-known fact intimately tied to China’s environmental disaster is its government’s secrecy and deception in dealing with pollution. Local authorities routinely cover up environmental disasters and fail to give timely warnings of toxic spills to the public. The central government in Beijing has been reluctant to release adequate pollution data, as they consider such information politically sensitive. Without transparency and candor, the Chinese government risks losing political credibility and public confidence, if it has not already done so. One bright spot on China’s environmental front is the growing aggressiveness and activism of the media, non-governmental organizations, and ordinary citizens. More and more, Chinese journalists and NGOs have been doing the hard work of exposing environmental scandals. And Chinese citizens have become less tolerant of the policy of “economic growth at all cost.” In recent years, residents in several cities have successfully blocked the construction of multi-billion dollar polluting projects. Riots and collective protests sparked by pollution are now among the fast growing “mass incidents” in China.

But the alternative would be too calamitous to contemplate. Horrendous humanitarian and economic consequences aside, business as usual on the environment could even spell the end of the Communist Party’s rule. The Chinese middle-class, which is particularly conscious of quality-of-life issues, could very well become a powerful source of opposition to the party if it concludes that the one-party state is responsible for their daily miseries: poisonous air, toxic water, and unsafe food. The case for decisive and quick action is compelling. The question is whether China’s ruling party will actually act, both for the long-term survival of the country and itself.
