From the cultural hub of Lahore down to the bustling ports of Karachi, smog is king in Pakistan, with citizens enduring unhealthy air quality for much of the year. The smog, generated mostly by crop and garbage burning and diesel emissions from furnaces and cars, could get worse by the end of this year when Pakistan opens five new Chinese-built coal power plants, funded by a $6.8 billion venture under the China-Pakistan Economic Corridor (CPEC) initiative. These five plants are just the beginning of the Pakistan government’s planned 7,560 MW expansion in coal power, which are CPEC-energy priority projects. “It’s a perfect storm for a pollution crisis,” said Michael Kugelman of the Wilson Center’s Asia Program. “The poor will continue to burn a variety of polluting materials to produce fuel, and now you’re also going to be introducing dirty coal into the mix. Combine that with crop burning in the countrywide and car exhaust fumes in rapidly growing cities, and you’ve got a really smoggy mess on your hands—and in your lungs.”

Huo Chang grows visibly exasperated as he speaks about his city’s water crisis. From his office in Beijing’s largest state-owned environmental investment and service company, China Energy Conservation and Environmental Protection Group (CECEP), the water expert explains how Beijing is in the throes of a population and economic boom that has left its water resources both polluted and depleted. In response to these opposing pressures, the city turned to controversial measures to avoid a Cape Town-like Day Zero crisis in which Beijing would no longer be able to meet the daily water needs of its population of nearly 22 million.

“China can simultaneously be the world’s biggest polluter and the leading developer and employer of clean energy technologies,” said Joanna Lewis, an associate professor of science, technology, and international affairs at Georgetown University’s Edmund A. Walsh School of Foreign Service at a recent event at The Brookings Institute on China’s local and global environmental agenda. “It’s not just megawatts being added, it’s actual investment in the innovation of these [renewable energy] technologies.”

“Historically, resource conflicts have often centered on fuel minerals, like oil. Future resources conflicts may however focus more on competition for non-fuel minerals that enable [modern] technologies,” said Andrew Gulley, Mineral Economist at the United States Geological Survey. America’s 2018 National Defense Strategy says that great power competition is the country’s most important defense challenge. Its key competitor for resources is China. Gulley was among several experts gathered at New America on September 20 to discuss the new competitive space and prospects for conflict or cooperation.

China—the world’s fastest-growing economy with the largest population—leads the world in cement production, the critical ingredient that has built China’s mammoth cities, sprawling roads, and other infrastructure. China pours 60 percent of the world’s cement; the country’s production in 2011-2013 surpassed U.S. production for the entire 20th century. While it paved the way for Chinese growth, it came at a dangerous cost: 1.6 million Chinese citizens die each year from respiratory illnesses linked to small particulate matter emissions, of which 27 percent come from cement production.

China is four years into its war on pollution, and while the skies over many of its cities are bluer and thousands of polluting industries have been closed, many challenges remain. According to China’s Ministry of Ecology and Environment, 16 percent of China’s soil is polluted, 239 of China’s 338 biggest cities failed to meet air quality standards in 2017, and 32 percent of China’s surface water is not clean enough to swim in. To confront these challenges, Chinese citizens and nongovernmental organizations (NGOs) are taking legal action to halt polluters, push local government to be more accountable, and strengthen enforcement of pollution laws—but most lack the legal experience and expertise needed to be successful. A series of workshops held by the Environmental Law Institute earlier this year sought to close this gap by training NGOs and legal professionals in China on best practices for environmental public interest litigation.

Access to and competition over natural resources has been one of the most common triggers for conflict. Throughout the centuries, countries and communities have fought over productive agricultural land, trade routes, spices, textiles, opium, and oil, to name just a few. But the battle over one natural resource—fish—has long been overlooked. As trends in the global fish industry increasingly mirror the conflict-ridden oil sector, fish may become the newest addition to the list of resources driving geopolitical competition. There are five parallels between oil and fish that call for increasing the sustainability of the fishing industry, or we might find ourselves facing what U.S. Coast Guard Captain Jay Caputo has called “a global fish war.”

In early January of this year, China’s “National Sword” policy banned imports of non-industrial plastic waste. The ban forces exporting countries to find new dumping grounds for their waste, which is estimated to total nearly 111 million metric tons by 2030. China’s decision has exposed deep structural flaws and interdependencies in the global waste management system. Western countries that have long depended on China to take their garbage are now struggling to deal with mounds of plastic trash, while China lacks the low-priced labor needed to effectively sort and process waste.
