China, the world’s biggest generator of green house gases, says it may need about 2.4 trillion yuan ($373 billion) of investment for its energy saving goals and anti-pollution measures under a five-year plan. The spending will reduce the energy consumption of China per unit of GDP (gross domestic product) by 2015 to 16 percent, the State Council said in a statement. But the government clarified nothing about who would fund that investment. The second-largest economy in the world is planning to shrink the energy usage of the country for energy savings equivalent to 670 million tons of standard coal by 2015.
