Since the reform and opening up, China's carbon dioxide emissions from 1978 148329×t increase to the 2008 689654xt, with annual growth of 5.3%. Meanwhile, the carbon dioxide emissions intensity a faster decline in general, but slow decline after 1999. Carbon dioxide emissions intensity in China is higher than international index. Because of glaciers and global warming, greenhouse gas emissions have attracted wide attention. December 2009, the UN climate change conference which held in the Danish capital Copenhagen also requires countries implement emission reduction goals, take action on climate change. Developing a low carbon economy has become the world trend. Modern cities are the subject of regional economic development, but also carbon emissions high-rises, low carbon urban construction is an important way to achieve a low carbon economy target. Environmental Kuznets curve (EKC) relation, taken as a dynamical law, indicates that environmental quality would deteriorate in the initial phases of the growth process, while, once surpassed some given threshold value of income level, further growth will go along with its improvement. Environmental Kuznets curve reveals environment qualities worsen with economic growth after the first appeared to improve relations. Based on economic growth and environmental pollution levels econometric model -- environmental Kuznets curve as the theoretical basis, Tianjin economic growth and the relationship between the carbon dioxide emissions is analyzed. It is reveals that environmental Kuznets curve has traditional environmental Kuznets curve shape, appearing different characteristics, showing "volatility u-shape + pour u-shaped".
