In an apparent firm demonstration of its commitment to reduce its gas emissions contribution, China has announced it will start controlling domestic production and corresponding usage of coal in the next five years through 2015.

Data released by the National Energy Administration, as contained in a five-year plan for the coal industry, revealed China will slash the production and demand of the raw commodity coal to 3.9 billion metric tonnes annually by 2015. In 2011, the world's second largest economy was able to comply with this requirement, with total output registered at 3.8 billion metric tonnes, Helen Lau, a Hong Kong-based analyst, said in Bloomberg News.

The administration said China's adjustments to its energy structure, environmental protection measures as well as restrictions particulates will inevitably create a significant impact on its coal production and usage.

Being the world's largest carbon-producing nation, China wants to actively control air pollution, at the same time is open to discussions leading to international cooperation and agreements that support climate change. The world's second largest economy wants to decrease the carbon dioxide emissions it sends to the air by 17 per cent per unit of gross domestic product through 2015, the five-year plan said.

China's local governments including Beijing, Shanghai and Guangdong this year swore to announce the results of readings made on air pollutants smaller than 2.5 micrometers in diameter, via the PM2.5. These pollutants, according to health and environment experts, can penetrate lungs and enter the bloodstream.
