Study On Carbon Emission Of Energy Resources Based On Structural Decomposition Analysis

As greenhouse gas emissions continue to increase,the climate problem has become a huge challenge that all humanity needs to face.As the major country of carbon emissions,China faces great pressure for reducing emissions.As a traditional industrial base in China,the second industry occupies a leading position in the overall economy in Liaoning Province for a long time.With the multiple promotion of urbanization and infrastructure construction and industrial development,the continuous increase in carbon emissions from the combustion of fossil fuels is inevitable.There is an inevitable conflict between economic growth and carbon reduction.According to China's commitment to reduce its carbon emission intensity by 40%-45%in comparison with 2005 in 2020,how Liaoning Province has achieved emission reduction commitments while developing its economy in line with the actual conditions in the region have become issues of concern and research.Based on the research object,this paper attempts to use the list method and the input-output method to calculate the energy carbon emissions of Liaoning Province based on the summary and analysis of existing literature.Further,the interference of price factors to the calculation of carbon emission intensity is eliminated by making the economic energy input and output table of the comparable price in 2007 and 2012.Uses the input-output method to calculate the direct carbon emission coefficient,complete carbon emission coefficient and other parameters,and the contribution of the three effects of technological innovation,production structure and final demand to different departments is analyzed by the method of structural decomposition analysis.The results of the study show that:?1?From 2007 to 2012,the total energy carbon emissions in Liaoning increased from33.162 million tons to 52.095 million tons,an increase of 189.33 million tons,the average annual growth rate of energy carbon emissions was 9.45%.While,the carbon emission intensity was from 1.07 t CO₂/million in 2007 reduced to 0.73 t CO₂/million in 2012.The overall energy efficiency in Liaoning Province has increased,but the total carbon emissions have not declined due to the continuous increase in production demand.The industrial sector is still the main producer of carbon emissions.?2?The analysis results of energy carbon emission coefficients show that,apart from the transportation industry with fossil fuels as the main production factors,the direct carbon emission coefficients of other industries are not significantly different,and they have declined to a certain degree from 2007 to 2012.In the comparison of the complete carbon emission factors we can see that the transportation industry and the secondary industry are still high-energy-consuming sectors,and their carbon emissions in the production process need to be further controlled.?3?The structural decomposition analysis results of energy carbon emissions show that carbon emission reduction caused by the use of new production technology in Liaoning Province is the main factor to restrain the growth of energy carbon emission.and the continuous growth of the final demand is the main factor of the continuous growth of carbon emissions.Carbon reduction in the production process requires scientific production planning and management.The growth rate of carbon emissions and intensity in the construction industry is prominent,which is related to the rapid development of the industry during this period.In the future research,we can pay attention to the carbon emission changes of the construction industry and formulate corresponding production and construction plans to realize the concept of green building.
