Calculation Of CO₂ Emissions And Analysis Of Potential Emission Reduction In Shaanxi Province

At present,the environmental problem of global warming is the most important environmental issue in the international community.Among them,carbon dioxide gas emitted by fossil energy accounts for 76%of the world's total greenhouse gases.Carbon dioxide has become a greenhouse gas that causes climate change and severe environmental pollution..In this context,China has played an exemplary role in addressing the issue of climate change,setting a banner for all developing countries and the entire international community.In June 2015,a document on China's independent contribution to climate change submitted to the Secretariat of the United Nations Framework Convention on Climate Change stated that�compared with 2005,China's domestic unit CO₂ emissions will be 2030 Reduction of 60%to 65%.Moreover,Shaanxi Province,as China's inland center,is a key province in the implementation of China's international cooperation strategy and domestic policy implementation.Therefore,this study has conducted relevant research on the CO₂ emissions generated by energy consumption in Shaanxi Province.This study selected 2001 as the research base year and 2015 as the termination year.During the 15-year review period,the coal,oil,and natural gas consumption in the Shaanxi Statistical Yearbook,and the IPCC National Greenhouse Gas Inventory Guide?2006?and the Provincial Government Corresponding calculation methods provided in the Compilation Guide for Grade I Greenhouse Gas Inventories calculate the total CO₂emissions from Shaanxi Province's three major energy sources from 2001 to 2015.The results show that from the perspective of the total CO₂ emissions of Shaanxi Province,the total CO₂ emissions of Shaanxi Province in 2001 were 83,146,200 tons,and the total emissions in 2015 reached 44506,690,000 tons,showing a straight upward trend,with an average annual growth rate of 12.73%;In terms of CO₂ emissions per capita in Shaanxi Province,the per capita CO₂ emissions in Shaanxi Province in 2001 were 2.28t/person,and the per capita CO₂ emissions in 2015 reached 11.73t/person,with an average annual growth rate of 12.41%.From the perspective of CO₂ emissions intensity in Shaanxi Province,The overall intensity of CO₂ emissions in Shaanxi Province showed a trend of rising first and then decreasing.In 2001,the intensity of CO₂ emissions was 4.14t/million,and in 2015 the intensity of CO₂ emissions dropped to 2.47t/million,with an average annual reduction rate of 3.62%.Based on the energy consumption and CO₂ emission situation and trends in Shaanxi Province from 2001 to 2015,this study uses the"top-down"scenario analysis method to set the economic development level to A₁?low-speed development scenario?and A₂?Medium-speed development scenario?,A₃?high-speed development scenario?;set emission reduction policies as B₁?baseline scenario?,B₂?optimized scenario?,B₃?low-carbon scenario?;set energy consumption structure as C₁?the energy structure is not optimized?and C₂?the energy structure is moderately adjusted?.Then one scenario was selected from the three main influencing factors for permutation and combination,and 18different combination scenarios were obtained.Finally,relevant models are used to calculate the energy consumption and corresponding CO₂ emissions of Shaanxi Province from 2016 to 2030 under different scenarios.The results show that when using low-speed economic development and low-carbon policies?A₁B₃ scenario?,whether the energy structure is C₁?the energy structure is not optimized?or C₂?the energy structure is moderately adjusted?scenario,CO₂ in Shaanxi Province from 2016 to 2030 Emissions are always at the lowest levels compared to other portfolio scenarios.And when the proportion of renewable energy and the annual replacement rate of renewable energy reach a certain ratio,the downward trend of CO₂ emissions will increase significantly.This study first analyzes the current status of low-carbon development in Shaanxi Province from four aspects:energy structure,energy utilization efficiency,environmental pollution and industrial structure;then,the main reasons for the current status of emissions are determined;finally,from the economic growth mode,The five basic aspects of industrial structure,energy utilization efficiency,energy consumption structure,and living consumption are given,and relevant measures and suggestions are given to help save energy and reduce emissions in Shaanxi Province.
