MIT: China’s pollution costs $112B in annual health care

China’s unprecedented growth is carrying a steadily steeper price tag as its air pollution hikes the nation’s health care costs, finds a new study by the Massachusetts Institute of Technology.

Although China has made substantial progress in reducing its air pollution, MIT researchers say its economic impact has jumped from $22 billion in 1975 to $112 billion in 2005. The costs result from both lost labor and the increased need for health care because ozone and particulates in air can cause respiratory and cardiovascular diseases.

“The results clearly indicate that ozone and particulate matter have substantially impacted the Chinese economy over the past 30 years,” Noelle Selin, an assistant MIT professor of engineering systems and atmospheric chemistry, said in announcing the findings that appear in the February edition of the journal Global Environmental Change.

The study, by researchers at the MIT Joint Program on the Science and Policy of Global Change, said pollution’s economic impact has grown, because population growth increased the number of people exposed to it and higher incomes raised the costs associated with lost productivity.

The study “finds that the damages are even greater than previously thought,” said Kelly Sims Gallagher, an associate professor of energy and environmental policy at Tufts University’s Fletcher School, in the MIT announcement.
