A STUDY OF EFFECTIVE GLOBAL WARMING COUNTERMEASURES AND MARGINAL ABATEMENT COST FOR THE CHINESE PREFECTURAL RESIDENTIAL SECTOR

In recent years, with improvements in living standards, energy consumption and CO2 emissions of Chinese residential sector have both increased considerably. However, we do not have a clear vision of future growth in energy consumption and lack tools for evaluating the impact of energy saving measures. This paper discusses the sustainability of Chinese residential buildings from the following 3 aspects: 1. Analyzing the future growth of energy consumption in Chinese residential buildings. 2. Evaluating the reduction potential of CO2 emissions through the implements of various energy saving measures. 3. Calculating the marginal abatement cost of proposed countermeasures and evaluating them from an economic perspective. As results, we found that efficiency policies could bring about 70% CO2 emissions reduction in maximum. Hence, most of the efficiency policies have positive effects on saving energy bills, thus the marginal abatement costs are able to be managed in a minus level.
