The curve of environmental impact in the process of economic growth in developed countries was likened to “environmental mountain”. For developing countries, particularly China, the right way of economic development is going through the “environmental mountain” on the halfway up the mountain - a new way for industrialization. The formulas of the relationship between environmental impact and GDP were derived, in which there are 2 key variables： g—growth rate of GDP; t—decreasing rate of environmental impact per unit GDP. Taking several countries and provinces in China as examples, the relationships between economic growth and energy consumption were studied. The environmental impacts of China in the years 2005, 2010 and 2020 were anticipated under different assumptions, and further discussion was given in terms of energy consumption.
