      摘要: 基于《聯(lián)合國氣候變化框架公約》(UNFCCC)附件一國家提交的1990年至最新清單年份(2020年)溫室氣體排放數據,探討了附件一國家CH4排放現狀、演變趨勢和關(guān)鍵排放源。結果表明:(1)2020年UNFCCC附件一42個(gè)國家CH4總排放量為187223.10萬(wàn)tCO?當量,美國、俄羅斯聯(lián)邦和澳大利亞CH4排放量總和已經(jīng)占到總排放量的60%。(2)與1990年相比,2020年UNFCCC附件一國家/集團CH4排放整體呈下降趨勢,美國、俄羅斯聯(lián)邦、澳大利亞、歐盟(公約)和歐盟(京都議定書(shū))分別下降14.79%、29.69%、 24.01%、40.56%和40.34%,而土耳其、西班牙、新西蘭和愛(ài)爾蘭分別增加了50.62%、2.49%、3.97%和7.91%。(3)主要發(fā)達國家CH4排放主要來(lái)自農業(yè)和能源部門(mén),其次是廢棄物部門(mén)。其中,在農業(yè)部門(mén)主要來(lái)自腸道發(fā)酵,其次是糞便管理;能源部門(mén)的CH4排放主要來(lái)自燃料的逃逸排放;廢棄物部門(mén)的主要排放源是固體廢物填埋處理。

      Abstract: The status, trends and key sources of CH4 emissions in Annex I countries are explored, based on GHGs emissions data from Parties submitted by Annex I countries to the United Nations Framework Convention on Climate Change (UNFCCC) from 1990 to the most recent inventory year (2020). The results show that: (1) In 2020, the total CH4 emissions of the 42 countries in Annex I of the UNFCCC were 187,223.1 kt CO?-eq, and the combined CH4 emissions of the United States, the Russian Federation and Australia accounted for 60% of the total emissions. (2) Compared with 1990, the overall CH4 emissions of Annex I countries/groups of UNFCCC showed a downward trend in 2020, of which United States, the Russian Federation, Australia, the European Union (Convention) and the European Union (Kyoto Protocol) decreased by 14.79%, 29.69%, 24.01%, 40.56% and 40.34% respectively, while Turkey, Spain, New Zealand and Ireland increased by 50.62%, 2.49%, 3.97% and 7.91% respectively. (3) CH4 emissions in major developed countries mainly come from the agricultural and energy sectors, followed by the waste sector. Among them, in the agricultural sector mainly from enteric fermentation, followed by manure management; CH4 emissions from the energy sector come mainly from escape emissions from fuels; The main source of emissions in the waste sector is solid waste landfills.

      Key words: UNFCCC, GHGs, CH4, Emission characteristics
