Rich Chinese Provinces ‘Outsource’ Pollution to Poor Ones

BusinessWeek: “A flurry of citizen-led protests against polluting (or proposed) chemical factories in Chinese cities has recently made headlines. And for good reason, as hundreds of peaceful marchers parading in front of government buildings and waving hand-made signs (such as “We Want to Survive” and “Say No to PX,” a hazardous chemical) isn’t something you see every day in authoritarian China.

In recent years, such environmental demonstrations have erupted in the prosperous coastal cities of Xiamen, Dalian, Ningbo, and the southern city of Kunming. Middle-class citizens, wielding smartphones and sharing information about pollutants via social media, have organized the protests. When developers’ plans have been put on hold—as happened last month in Kunming—popular Chinese and Western media have declared a victory for nascent people power in China.

But what happens next? Chances are that factory plans won’t fizzle entirely, but rather that construction will move to another location—usually in a poorer province, with a less informed and media-savvy local population.

In a paper published in the June 10 issue of the Proceedings of the National Academy of Sciences (pdf), researchers at the Chinese Academy of Sciences, University of Maryland, and University of Cambridge mapped the flow of goods, money, and interprovincial emissions to document what they call the “outsourcing” of pollution “within China.” Their study focused in particular on CO2 emissions, which spew from the same coal-fired power plants and other factories responsible for smog-causing domestic pollution.

As the researchers discovered, “the most affluent cities of Beijing, Shanghai, and Tianjin, and provinces such as Guangdong and Zhejiang, outsource more than 50% of the emissions related to the products they consume” to provinces in the central and western hinterlands. In short, eastern urbanites enjoy the fruits of energy, steel, cement, and other goods produced in China’s less-developed regions. (To be sure, Western consumers also benefit from goods produced in China, at an even greater distance from the pollution.)

“Although China is often seen as a homogeneous entity, it is a vast country with substantial regional variation in physical geography, economic development, infrastructure, population density, demographics, and lifestyles” the researchers wrote. One example: The carbon footprint of residents of Shanghai, Beijing, and Tianjin, three wealthy eastern cities, is four times higher than that of residents of Guangxi, Yunnan, and Guizhou, three poor southwestern provinces.”

* Millions of tonnes of rural refuse are dumped in waterways a year, bill says

So it’s not only factories and chemical plants that are at fault.  Common rural folk are too!

SCMP: “Many were shocked when thousands of dead pigs were found floating on Shanghai’s Huangpu River this month, but animal carcasses are not the only things that end up in the nation’s waterways.

Rivers and lakes are among the major dumping sites of some 190 million tonnes of household waste generated in rural areas every year, most of which are casually dumped without being recycled or properly treated, according to a bill submitted to the annual session of the Chinese People’s Political Consultative Conference in Beijing last week.

Research by the China Association for Promoting Democracy, one of the mainland’s eight non-communist political parties, shows that most household refuse in the rural areas is piled on the side of roads, dumped under bridges, in fields or on river banks, or simply burned.

Researchers said the variety and amount of rural waste had risen markedly over the past decade as living standards improved.

In rural areas, household refuse used to comprise mainly of kitchen waste and ash from burning coal or firewood, but Wang Jinxia, a researcher at the Chinese Academy of Sciences‘ Centre for Chinese Agricultural Policy, said there was now more plastic packaging, sanitation products and even furniture in the thrown-away waste.

Wang said the limited amount of household waste, most of it biodegradable, could be absorbed by nature’s self-cleaning capacity in the past, but now the amount and variety of trash had far exceeded that capacity, threatening the environment.

“It [dumping refuse in rivers] is a rather prevalent phenomenon … in some extreme cases, the rivers are even clogged,” Wang said.

In the past month, photos have been posted online in a campaign to record polluted rivers, some completely covered by garbage. A stream in the Yongding county of Fujian province was used as a dump for waste including glass bottles, plastic bags, used lanterns and even furniture.

Last month, a Zhejiang businessman offered a 200,000 yuan (HK$247,000) reward to an environmental official in Ruian in challenging him to swim in a river full of household refuse and waste rubber from a shoe factory.

Every summer, 150,000 to 200,000 cubic metres of refuse is retrieved from the reservoir above the massive Three Gorges Dam to prevent it from jamming the floodgates, official media reports say. The waste include tree branches washed into the Yangtze by torrential rains, but most of it is household refuse from families living along the river’s upper reaches. Some rivers in cities have also become casual dump sites. For example, The Beijing News reported this month that the authorities had retrieved more than 10,000 corncobs from the moat of the Forbidden City – among the four tonnes of refuse that tourists threw into the Tongzi River.

Some sections of the waterway in the old town of Lijiang , a popular city for tourism in Yunnan province, were also found to be congested with plastic bottles, disposable tableware and other refuse, China National Radio reported last year, while some restaurants were accused of discharging their wastewater – containing grease and detergent – directly into the river.

The mainland banned the dumping of household refuse and industrial waste in rivers, lakes, canals and reservoirs in 2004 when the Solid Wastes Pollution Prevention Law was amended.

But researcher Wang, who did a survey of about 120 villages in seven provinces in 2010, said there was no such government oversight in some regions.

The high cost of refuse collection and treatment had also discouraged some local governments from tackling the problem, Wang said. For instance, a town with 50,000 residents would need to spend at least 3.5 million yuan a year for proper waste disposal, Wang said.

“Without a public service to collect and cart away the trash, people in rural villages have no choice but to dump it in the waterways or fields,” she said.”
