Review on the Theory of Ecological Environment Damage Assessment

In the rapid industrialization and urbanization of China,the damage of ecological environment hinders the people's pursuit of good environmental quality.As a technical means of ecological environment protection,the assessment of ecological environment damage has been attached great importance by all walks of life.However,there are still some problems in the current practice of environmental damage assessment.Therefore,based on the understanding of ecological environment damage assessment and related concepts,this study systematically studies the theory of ecological environment damage assessment.Based on the research,it can be seen that the assessment of ecological environment damage is the inevitable product of social and economic development and the promotion of environmental protection awareness,and ecological environment damage belongs to the subordinate concept of"environmental damage".The assessment of ecological environment damage includes the assessment of ecological damage and environmental damage,paying attention to the interests of human society and the unclaimed pure environment and pure ecological damage.The assessment of ecological environmental damage determines the goal and direction for the construction of environmental damage compensation system.This study enriches the theory of environmental damage assessment and provides theoretical reference and method basis for environmental damage assessment.

Environmental Issues in the Mining Sector of Mongolia

This research is the summary of the results of the environmental damage assessment and rehabilitation cost estimation works carried out involving in total, 242 gold-placers’ licensed areas, within the framework of implementation of the “Law on Prohibiting Exploration and Mining of Minerals at Sources of Rivers and Streams, within Protected zones of Water basins and Forest funds”, adopted by the Parliament of Mongolia, in 2009.

Marginal cost pricing for coal fired electricity in coastal cities of China:The case of Mawan Electricity Plant in Shenzhen City, China

By developing a GDMOD model to estimate the environmental externalities associated with electricity generation, this project provides a detailed analysis of the damages and costs caused by different pollutants at varying distances from the Mawan Electricity Plant in Shenzhen, China. The major findings of this study can be summarized that (1) environmental damages caused by electricity production are large and are mainly imposed on regions far away from the electricity plant; (2) air pollution is the most significant contributor to the total damages, and SO_2, NOx, and particulate matter are the three major pollutants with highest damages; (3) the damages caused per unit of particulate, NOx, and SO_2 emissions are much higher than pollution treatment and prevention costs. The research results of this project showed that China needs to have a more effective levy system on SO_2, and a more manageable electricity tariff mechanism to internalize the environmental externalities. The results have also implications for pollution control strategies, compensation schemes as well as emission trading arrangements.

How Green is China＇s Path of Catching Up？ An International Comparative Evaluation

China＇s rise as a global economic power in recent decades has been achieved with tremendous environmental costs. Has China been an abnormally heavier polluter in its development path？ How has pollution accounted for China＇s hyper economic growth？ This study answers these questions by evaluating the environmental effects of China＇s growth using a data set of 61 countries over a period of four decades. The analysis is focused on two pollutant emissions： CO2 emissions, which carry global externalities, and particulate emissions, of which the environmental cost is more domestic. A fractional polynomial （FP） regression model is estimated to project emissions levels per worker based on lagged values of per capita GDP and other variables. It reveals that China＇s CO2 emissions have been higher than the projection for most years with an average margin of over 5.3% while its particulate emissions have exceeded projection by an average margin of more than 7.5%. The excessive emissions levels of both pollutants confirm the severity of China＇s environmental challenges and indicate great potential for the economy to work for a greener growth pattern. On the other hand, contributions of emissions to multi-factor productivity （MFP） growth are estimated by FP regressions based on a human-capital augmented growth model. The results show opposing trends of CO2 and particulates in their ＂contributions＂ to GDP growth, which imply asymmetric incentives to abate the two types of pollution. These findings have important implications for China＇s environmental policy making.
