Inventory Of Non-CO₂ Greenhouse Gas Emissions In Shaanxi Province

In this paper,the non-CO₂ emission inventory of Shaanxi Province from 2016 to2021 was compiled based on the data collected in the accounting of energy sector,indus-trial production sector,agricultural sector and waste disposal on the basis of consulting statistical yearbook and various literatures,and according to the calculation formulas in the IPCC National Greenhouse Gas Inventory Guide and the Provincial Greenhouse Gas Inventory Compilation Guide.At the same time,the emission characteristics of various emission sources were analyzed to calculate the non-CO₂ emissions per capita,per unit area and ten thousand yuan of GDP in Shaanxi Province,and to predict the non-CO₂emissions and trends from 2022 to 2030 in Shaanxi Province.（1）From 2016 to 2021,the CH₄ emission in Shaanxi Province increased year by year,with the highest emission of 6,923,200 tons in 2021 and the lowest emission of5,234,800 tons in 2016.Energy activities were the main source of methane emission,followed by agricultural activities and waste treatment.From 2016 to 2021,N₂O emission in Shaanxi Province showed a trend of first increasing,then decreasing and then increas-ing.From 2016 to 2021,the emission of HFCs in Shaanxi Province showed a trend of first increase and then decrease,with the lowest emission of 0.01,005 tons in 2016 and the highest emission of 0.01,007 tons in 2017.From 2016 to 2021,the lowest emission of PFC_S in Shaanxi Province was 0.0027 million tons in 2018 and the highest emission was 0.0031 million tons in 2020.From 2016 to 2021,SF₆ emission in Shaanxi Province showed an overall increasing trend,with the highest emission being 0.02,221 tons from2019 to 2021 in 2022 and the lowest emission being 0.01,960 tons in 2016.（2）It is estimated that from 2016 to 2021,non-CO₂ emissions per capita and per unit area of Shaanxi Province show an increasing trend year by year,in which the per capita non-CO₂ greenhouse gas emissions increase from 4.58 t/cap to 5.12 t/cap.non-CO₂green-house gas emissions per unit area increased from 9.42 t/hm² to 13.75 t/hm².In Shaanxi Province,non-CO₂ greenhouse gas emissions per 10,000 yuan GDP decreased year by year from 2016 to 2021.（3）Combined with the main influencing factors of various non-CO₂ greenhouse gas emission sources in Shaanxi Province,based on the recent planning goals of Shaanxi Province and the country,the benchmark scenario and low-carbon economic policy sce-nario are set for the main influencing factors of various emission sources,and the non-CO₂emission trend of Shaanxi Province from 2022 to 2030 is predicted.
