Haikun Wang, Xiaojing He, Xinyu Liang, Ernani F. Choma, Yifan Liu, Li Shan, Haotian Zheng, Shaojun Zhang, Chris Nielsen, Shuxiao Wang, Ye Wu, and John Evans. 2020. “Health benefits of on-road transportation pollution control programs in China.” Proceedings of the National Academy of Sciences, 117, 41, Pp. 25370-25377. Publisher's VersionAbstract
China started to implement comprehensive measures to mitigate traffic pollution at the end of 1990s, but the comprehensive effects, especially on ambient air quality and public health, have not yet been systematically evaluated. In this study, we analyze the effects of vehicle emission control measures on ambient air pollution and associated deaths attributable to long-term exposures of fine particulate matter (PM2.5) and O3 based on an integrated research framework that combines scenario analysis, air quality modeling, and population health risk assessment. We find that the total impact of these control measures was substantial. Vehicular emissions during 1998–2015 would have been 2–3 times as large as they actually were, had those measures not been implemented. The national population-weighted annual average concentrations of PM2.5 and O3 in 2015 would have been higher by 11.7 μg/m3 and 8.3 parts per billion, respectively, and the number of deaths attributable to 2015 air pollution would have been higher by 510 thousand (95% confidence interval: 360 thousand to 730 thousand) without these controls. Our analysis shows a concentration of mortality impacts in densely populated urban areas, motivating local policymakers to design stringent vehicle emission control policies. The results imply that vehicle emission control will require policy designs that are more multifaceted than traditional controls, primarily represented by the strict emission standards, with careful consideration of the challenges in coordinated mitigation of both PM2.5 and O3 in different regions, to sustain improvement in air quality and public health given continuing swift growth in China’s vehicle population.

China Project Spring 2018 Newsletter

May 22, 2018

This spring the Harvard-China Project continued its investigations of the “China 2030/2050” theme sponsored by the Harvard Global Institute (HGI). Our community explored a number of pressing issues, including a Nature Energy paper on the environmental implications of electric vehicle charging in China. The research, which offers a strategy for reducing CO2 emissions and improving air quality with electric vehicles in Beijing, was authored by a Harvard-Tsinghua...

High-Level Meetings with Ministers Xie and Li

August 30, 2017

On August 4, China’s lead official on climate change, Minister XIE Zhenhua, hosted a research and policy consultation with Profs. Mike McELROY, Steve WOFSY, executive director Chris NIELSEN, and Project alumni Dr. ZHANG Hongjun (Holland & Knight, LLP) and Prof. LU Xi (Tsinghua University) at his offices in Beijing. Discussion topics included the state of U.S.-China engagement on climate and the growing role of subnational governments, disparate regional capacities for carbon control within China...

Ying Zhou, Jonathan I Levy, James K Hammitt, and John S Evans. 2007. “Population exposure to pollutants from the electric power sector using CALPUFF.” In Clearing the air: The health and economic damages of air pollution in China, edited by Mun S Ho and Chris P Nielsen. Cambridge, MA: MIT Press. Publisher's VersionAbstract

An interdisciplinary, quantitative assessment of the health and economic costs of air pollution in China, and of market-based policies to build environmental protection into economic development.

China's historic economic expansion is driven by fossil fuels, which increase its emissions of both local air pollutants and greenhouse gases dramatically. Clearing the Air is an innovative, quantitative examination of the national damage caused by China's degraded air quality, conducted in a pathbreaking, interdisciplinary U.S.-China collaboration. Its damage estimates are allocated by sector, making it possible for the first time to judge whether, for instance, power generation, transportation, or an unexpected source such as cement production causes the greatest environmental harm. Such objective analyses can reset policy priorities.

Clearing the Air uses this information to show how appropriate "green" taxes might not only reduce emissions and health damages but even enhance China's economic growth. It also shows to what extent these same policies could limit greenhouse gases, suggesting that wealthier nations have a responsibility to help China build environmental protection into its growth.

Clearing the Air is written for diverse readers, providing a bridge from underlying research to policy implications, with easily accessible overviews of issues and summaries of the findings for nonspecialists and policymakers followed by more specialized, interlinked studies of primary interest to scholars. Taken together, these analyses offer a uniquely integrated assessment that supports the book's economic and policy recommendations.

In 1995, daily mortality in a district of Chongqing, China, was analyzed from January through
December for associations with daily ambient sulfur dioxide and fine particles (airborne particles
with diameters ≤ 2.5 μm; PM2.5). The mean concentration of PM2.5 was 147 μg/m3 (maximum,
666 μg/m3), and that of SO2 was 213 μg/m3 (maximum, 571 μg/m3). On average, 9.6 persons
died each day. We used a generalized additive model using robust Poisson regression to estimate
the associations of mean daily SO2 and PM2.5 with daily mortality (on the same day and at lags up
to 5 days) adjusted for trend, season, temperature, humidity, and day of the week. The relative
risk of mortality associated with a 100 μg/m3 increase in mean daily SO2 was highest on the second
lag day [1.04; 95% confidence interval (CI), 1.00–1.09] and the third lag day (1.04; 95% CI,
0.99–1.08). The associations between daily mortality and mean daily PM2.5 were negative and statistically
insignificant on all days. The relative risk of respiratory mortality on the second day after
a 100 μg/m3 increase in mean daily SO2 was 1.11 (95% CI, 1.02–1.22), and that for cardiovascular
mortality was 1.10 (95% CI, 1.02–1.20). The relative risk of cardiovascular mortality on the
third day after a 100 μg/m3 increase in mean daily SO2 was 1.20 (95% CI, 1.11–1.30). The relative
risks of mortality due to cancer and other causes were insignificant on both days. The estimated
effects of mean daily SO2 on cardiovascular and respiratory mortality risk remained after controlling for PM2.5.
Clearer Skies Over China: Reconciling Air Pollution, Climate, and Economic Goals
2013. Clearer Skies Over China: Reconciling Air Pollution, Climate, and Economic Goals. Cambridge, MA: MIT Press. Publisher's VersionAbstract

A groundbreaking U.S.–Chinese inquiry into the effects of recent air pollution controls and prospective carbon taxes on China's economy and environment.

China's carbon dioxide emissions now outstrip those of other countries and its domestic air quality is severely degraded, especially in urban areas. Its sheer size and its growing, fossil-fuel-powered economy mean that China's economic and environmental policy choices will have an outsized effect on the global environmental future. Over the last decade, China has pursued policies that target both fossil fuel use and atmospheric emissions, but these efforts have been substantially overwhelmed by the country's increasing energy demands. With a billion citizens still living on less than $4,000 per year, China's energy and environmental policies must be reconciled with the goals of maintaining economic growth and raising living standards.

This book, a U.S.–Chinese collaboration of experts from Harvard and Tsinghua University, offers a groundbreaking integrated analysis of China's economy, emissions, air quality, public health, and agriculture. It first offers essential scientific context and accessible summaries of the book's policy findings; it then provides the underlying scientific and economic research. These studies suggest that China's recent sulfur controls achieved enormous environmental health benefits at unexpectedly low costs. They also indicate that judicious implementation of carbon taxes could reduce not only China's carbon emissions but also its air pollution more comprehensively than current single-pollutant policies, all at little cost to economic growth.
