Research On Carbon Emission Reduction Potential Of Public Buildings From The Perspective Of Carbon Trade

In order to control carbon dioxide emissions and build ecological civilization,China has actively taken actions to save energy and reduce emissions.One of the key targets of emission reduction work is the construction sector,with public buildings being the most prominent.Therefore,it is very important to control the carbon emission of public buildings.As a method to control carbon emissions,carbon emission trading mechanism has received extensive attention and research from scholars in various countries since it was proposed,and has been practiced in some countries and regions.Relevant research and practice show that carbon trading mechanism can effectively control carbon emissions and stimulate the value of environmental resources.Therefore,this paper takes public buildings as the research object to explore the impact of the establishment of carbon trading mechanism on the carbon emissions of public buildings,with the aim of providing new ideas for China's carbon emission reduction.Starting from the promotion of carbon emission reduction in public buildings,this paper studies the potential of carbon emission reduction in public buildings during their operation phase from the perspective of carbon trading.Firstly,the related theories and data of public buildings,carbon emissions and carbon emission trading are systematically reviewed.Secondly,on the basis of summarizing the characteristics of carbon emission from public buildings,the shortcomings of traditional carbon emission reduction policies in the field of public buildings are elaborated,and the applicability of carbon trading mechanism in carbon emission reduction from public buildings is analyzed.Then,a dynamic model of carbon emission reduction system for public buildings based on carbon trading mechanism is constructed.Finally,according to our country's carbon trading pilot experience and relevant literature,Guangdong Province is taken as an example for empirical research.The research shows that,first,carbon trading mechanism can make up for the shortcomings of traditional carbon emission reduction methods for public buildings,can better reflect and realize the value of carbon dioxide emission rights for public buildings,and can mobilize the owners' willingness to reduce emissions.Second,different carbon trading factors in the carbon trading mechanism also have different impacts on the carbon emission reduction effect.Factors with large impacts,such as the annual reduction rate of carbon emission rights quota,should be strengthened,and the combination of various factors should be paid more attention to so that the established carbon trading policy can achieve better emission reduction effect.Third,public buildings under the carbon trading mechanism not only have great emission reduction potential(under the set carbon trading scheme,the carbon emissions of public buildings in Guangdong province can be reduced by up to 29.93%by 2030),but also have a variety of emission reduction benefits,such as environmental benefits and economic benefits.At the same time,such benefits will be significantly improved with the gradual increase of implementation time and carbon trading activity.Fourth,the emission reduction potential of public buildings shows that the implementation of carbon trading mechanism in the field of public buildings will contribute to easing the energy pressure and building ecological civilization in our country.Based on the empirical results,this paper puts forward the following suggestions for improving the carbon trading mechanism and realizing the carbon emission reduction potential of public buildings:(1)strengthening the support of laws,regulations and policies;(2)Formulate and perfect the statistical database of public building energy consumption;(3)Establishing incentive system for carbon emission reduction in public buildings and implementing differentiated incentive policies for carbon emission reduction;(4)Improve the transaction operation guarantee mechanism to effectively reduce transaction costs.
