The phrase “Green Economy” was first mentioned in ‘Green Economy Blue Book’ by the British economist Pierre published in 1989. Green Economy promotes economic growth, instead of blocking it in the name of protecting the environment. It advocates changing extensive economic growth with the features of big investment, huge consumption, and serious pollution into intensive economic growth with the features of high efficiency, less resource-consuming, and less waste discharging and calls for harmony between economic and social growth and the proper load that nature can bear. As a new economic model aiming at harmonious development of economy and environment, Green Economy can fully satisfy the requirements of the scientific outlook on development of harmony and people first with energy saving and environmental protection as its goal.
