PM 2.5 particles, which are the smallest and most harmful to health, should not exceed the health threshold set by the World Health Organization (WHO) and which recommends a limit of 25 micrograms.
The Beijing Environment Report 2014, released by the municipal government environmental agency, reveals that the average of the nitrogen dioxide emissions also exceeds the standards, while those for sulfur dioxide and nitrogen oxide fell 9.35 percent and 9.24 percent, respectively.
Beijing launched a new program to measure and reduce pollution levels at the end of March to replace the previous one, launched in October 2013.
In addition, his government has announced that in 2016 it will close the only coal-fired power plant that remains active in the city.
In this new pollution framework, the orange alert - the second most serious after the red one - will be decreed from the 200 micrograms concentration per cubic meter of PM 2.5 particles, and the red one will only be activated when the levels remain above that figure for at least three days.
In an effort to combat pollution, Beijing recently decided to shut down coal plants, China's main source of energy, and both in the capital and other cities will be replaced by others powered by natural gas, a less polluting fuel.
Natural gas is called to be one of the pillars in the energy supply of the second world economy in the medium and long term.
