Research On Determination Of Carbon Emission Target Of Urban Residential Buildings Under The Background Of Carbon Peak

With the rapid development of China’s socio-economic,China has become the country with the most carbon emissions in the world.The Chinese government attaches great importance to climate change and energy conservation and emission reduction.In order to reflect the responsibility of a responsible major country,the Chinese government proposes that carbon dioxide emissions will reach the peak by 2030,strive to achieve carbon neutrality by 2060,and commit to China’s carbon emissions per unit of GDP in 2030.It will be 60-65% lower than in 2005.The civil construction sector accounts for about one-fifth of the country’s carbon emissions,which is a huge proportion.At the same time,China is also facing a huge gap in carbon emissions between provinces.Therefore,scientific and reasonable setting of carbon emission targets for urban residential buildings in 2030,and inter-provincial allocation of them to reduce inter-provincial inequality,has important research significance for promoting China to better achieve carbon emission targets in 2030.First of all,the scope and method of carbon emission accounting for urban residential buildings,which are the research objects in this thesis,are defined,and the basic principles of STIRPAT environmental impact factor model,entropy distribution method,Theil index and Gini coefficient are analyzed in detail,and the above methods are described in this article.The adaptability of carbon dioxide is analyzed,which provides theoretical support for carbon emission prediction and distribution in the following article.Secondly,based on the calculation of carbon emissions from urban residential buildings,the status quo of carbon emissions was analyzed,and the influencing factors of carbon emissions were established from the four perspectives of population,economy,and technology,and the size of each influencing factor was clarified through the STIRPAT model.,And built a carbon emission prediction model.Starting from the needs of urban residential buildings,after completing the 2030 scenario setting,the carbon emissions of urban residential buildings in 2030 are predicted.At the same time,starting from the proportion of civil buildings in the total carbon emissions of the country,2030 is set based on the carbon emission intensity in 2030.The upper limit of annual carbon emissions has finally established the total carbon emissions target of urban residential buildings in 2030: 1.331 billion tons.Finally,starting from the current status of inter-provincial carbon emissions,it is found that both the total and per capita carbon emissions present a pattern of "high in the north and low in the south",and through the Theil index analysis of the difference degree,it is found that climate has a huge impact on the difference in carbon emissions.Based on the hereditary principle of fair distribution,the principle of affordability and the principle of egalitarianism,as well as the principle of climate zone established through the analysis of the difference degree,the carbon emission distribution index was established: the cumulative per capita picture,the ability to pay index,the number of population and the climate index,and then passed The entropy method gives weights to each distribution index,distributes inter-provincial carbon emissions in 2030,and the distribution results pass the fairness test of Theil index and Gini coefficient.According to the distribution results,the provinces are divided into four categories from the perspective of emission space: emission space deficit type,emission space tight type,relatively sufficient emission space type and rich emission space type.
