The Cost And Benefit Analysis Of Carbon Dioxide Reduction In Tianjin

The government designated 13 provinces and cities, including Tianjin, as the first low-carbon pilot areas in 2010. Tianjin is an important city which is famous for its industrial and manufacturing development, and while promoting the environmental quality, carbon dioxide reduction will have a great impact on the economic development. Therefore, it is important to analyze the impact of carbon dioxide emissions both on economy and environment, which has a practical and typical significance.Through establishing a multi-objective model and ecological footprint analysis, this paper analyzes and predicts the macro-economic cost and the improvement degree of environment. Research shows that Tianjin’s economic cost of carbon dioxide reduction in 2014 is 5097.9-8136.4yuan per ton, and the additional 1% reduction will lead to a growth of economic cost, which is from 0.38% to 0.72%. It indicates that the pressure from carbon dioxide emissions to the economy increases gradually with the growth of reduction. Besides, the ecological footprint per capita increases gradually, while the footprint per unit carbon dioxide continues to decline. The footprint per unit carbon dioxide in 2014 is 0.1107hm2 per 10000 tons, and the average decline rate is 1.4%. The decrease of this indicator reflects the environmental benefits, which refers to the decline of emissions intensity. At the same time, it must be noticed that the decrease is small, which indicates that the carbon dioxide reduction is a long and arduous process. The paper then further develops some policies and measures about the carbon dioxide reduction.The main innovations of this paper are as follows:firstly, its study is from the microscopic point of view, and the object of study is a specific low-carbon pilot city. Secondly, it analyzes and forecasts about the cost and benefit of carbon dioxide reduction respectively, which helps to get a more comprehensive evaluation. Finally, it breaks the limitation that the environmental improvement can’t be evaluated by money, it measures and predicts the environmental benefits from the carbon dioxide reduction, by using "ecological footprint" as the indicator.
