Pollution could contribute to 257,000 deaths over the next decade

China's Toxic Air Could Kill a Population the Size of Orlando

If China met those standards, says Greenpeace in this latest report, nearly half of the premature deaths could be avoided.

The research is also notable because it was conducted jointly by China's best known and most prestigious university, Peking University (known locally as Beida), and Greenpeace, the international environmental advocacy group that has had a long and complicated relationship with China's authoritarian officials. The study was widely reported by state-run media, in another sign China's censors are loosening some restrictions around environmental reporting in the country in the face of intense public pressure for transparency.

The report adds to the growing amount of literature about the deadly impacts of the country's smog. An article that appeared in the The Lancet last year said that air pollution caused 350,000 to 500,000 premature deaths a year. An earlier Lancet study reported that air pollution caused 1.2 million premature deaths in 2010 alone.
