Whenever some survey results related to pollution causing countries are announced, we can expect China in the list. But to everyone’s surprise it has taken lot of steps to create green environment and to sustain it, it is the leader in clean energy efforts now outstripping the United States and Japan and leaving Australia lagging far behind. China is now commanding the largest market share of clean energy investment at a global level as a result. It shuts down more than 100 small coal-fired power plants for cleaner coal stations by 2011, which would reduce emissions by 15 per cent. It also offered subsidies worth billions of yuan for green energy projects, aiming to generate 15 per cent of the nation's total energy from renewable sources by 2020. It is to be noted that none of the countries took any steps to control pollution after last year's global climate summit at Copenhagen.
