"There's less to it probably than meets the eye," Adams said of the new action plan.
"Of course, saying it out loud does send a signal that the government is serious about, at least, decreasing the rate at which coal consumption grows and about getting more renewables and natural gas and nuclear," he said. "I think possibly just as important, if not more important, is the signal that it sends to the Chinese people that, 'we are trying to control pollution levels on the eastern seaboard.'"
The government has come under increasing pressure from the growing middle class to clean up the country's air pollution, much of which comes from the burning of coal.
The State Council said the country's air pollution situation is "grim" and is "harming people's health and affecting social harmony and stability." The action plan calls for the density of fine particulate matter a gauge of air pollution in Beijing to drop by 25 percent by 2017 from 2012 levels and by at least 10 percent in cities nationally.
It aims to raise the share of non-fossil fuel energy such as solar and wind power to 13 percent by 2017. It was 9.1 percent last year.
Environmental campaign group Greenpeace welcomed the plan, saying it would set an important precedent that should be extended throughout China and followed by other major countries.
"China's political leadership has set an ambitious timeline to solve China's air pollution crisis, responding to the mandate set by the Chinese public, especially in the heavily polluted cities around Beijing," Li Yan, climate and energy campaign manager at Greenpeace East Asia, said in a statement.
"The targets can only be met by tackling China's coal consumption growth and the plan takes very important steps in that direction," she said.
