At the September 2019 United Nations General Assembly (UNGA) Climate Summit, the U.S. delegation, under the shadow of intended withdrawal from Paris, did not volunteer a speaker. Attention instead focused on China. As the world’s largest carbon emitter, China was poised to assert leadership on the climate crisis.  However, perhaps lacking the sibling rivalry pressure that brought the U.S. and China together in 2014 on a joint climate agreement, State Councilor and Foreign Minister Wang Yi offered no new commitments: no carbon tax, no increased investment in renewables, and no announcement to set a more ambitious coal consumption cap.

Residents of Chennai, by all accounts, are miserable and anxious. The city’s main reservoirs are dry, depleted by the failure of successive monsoons to provide replenishing rains. The shortfall has crippled the piped distribution network, which is now meeting just half of typical demand through a mix of secondary sources: desalinated water, groundwater, and the impoundments from nearby stone quarries. Even that supply is far from adequate. Piped water reaches households once a week or less. Tanker trucks, an expensive alternative, dole out water by the bucketful to desperate crowds.

China’s war on pollution and goals to lower carbon emissions are noteworthy as the United States takes a back seat in the global energy transition. Cleaner air and low carbon efforts in China could significantly change the country’s environmental health story and contribute to global efforts to lower greenhouse gas emissions. However, China’s energy reforms look less green now than they seemed after Paris in 2015. While China’s rate of increase in CO₂ emissions has slowed and the share of renewables in its energy mix continues to grow, the Chinese government’s pursuit of clean air along its east has shifted more polluting and water-intensive coal-fired power development into the country’s west. To continue to lead the way in this “Asian Century,” China must further incorporate water-saving reforms into its energy and environment plans.

Doula Village lies 55 kilometers (34 miles) northeast of New Delhi on a flat expanse of Uttar Pradesh farmland close to the Hindon River. Until the 1980s Doula Village’s residents, then numbering 7,000, and its farmers and grain merchants, thrived on land that yielded ample harvests of rice, millet, and mung beans. The bounty was irrigated with clean water transported directly from the river, or with the sweet groundwater drawn from shallow wells 7 meters (23 feet) deep.

BENGALURU, India – In a small town in the suburbs of this booming city, K.V. Muniraju knows all too well the decade-old battle of securing water for his crops. With groundwater tables continuously falling, the middle-aged farmer once borrowed heavily to dig wells ever deeper.

A quarter of the coal that powers China’s economy is mined in Inner Mongolia, one of the country’s most water-scarce provinces with only slightly under two percent of China’s total water resources. The coal-rich city of Ordos, which produces nearly 70 percent of all the coal in Inner Mongolia, is bookended by expanding deserts—Kubuqi to the north and Maowushu to the south—and may one day run out of water and face a “Day Zero” like Cape Town in South Africa. Both the central and local governments are promoting a number of efforts to create new water supplies in Ordos, such as treating brackish waters and trading water rights. To learn more, the China Energy & Environment Forum recently interviewed Shaofeng Jia, the Deputy Director of Water Resources Research Center at the Chinese Academy of Sciences, who recently completed an extensive study on water-energy confrontations in Inner Mongolia.

Chinese cities are being encircled by untreated sludge—a pungent, viscous mixture of human excreta and stormwater runoff. Four years ago in Beijing, trucks loaded with untreated sludge from the city’s largest wastewater treatment plant were illegally dumping mountains of sludge in the outskirts of the capital as “free fertilizer” for peri-urban farms. Similarly, in the southern China city of Guangzhou, disposing toxic sludge into the nearby river required nothing more than a hired boat. From the far western desert city of Urumqi to the eastern metropolis of Shanghai, more and more of China’s cities are struggling to manage mountains of sludge and municipal waste, as well as floods of wastewater and stormwater runoff. 

Coal — the reigning king of China’s energy sector — generates 74 percent of the country’s electricity and is the main source of the staggering air pollution blanketing Chinese cities. Prompted in large part by the air pollution problem, the Chinese leadership has begun to pivot away from coal by strengthening monitoring and enforcement to limit coal-fired power plant emissions, piloting CO₂ emissions trading projects, accelerating expansion of renewables, and committing to CO₂ reductions in the Paris climate agreement.
