Examination of greenhouse gas emissions is crucial for understanding the global warming. For this reason, identification of the sources of greenhouse gas emissions is crucial. This paper presents a hybrid multi criteria decision making method, which combines analytic hierarchy process and technique for order preference by similarity to ideal solution and compares this method with actual data for identifying the risk priority of sources of greenhouse gas emissions. For this purpose, the historical data of 25-years, for six-greenhouse gas sources and three-greenhouse gases (CO₂, CH_4, N₂O) are considered. Consequently, it was found that while incineration of wastes caused the minimum GHG emissions, energy sector caused the maximum GHG emissions. The results of this paper show that use of this hybrid method is easy and intelligible, and has a good potential for sorting the risk priority of sources of greenhouse gas emissions.

检查温室气体排放对于了解全球变暖至关重要。因此，确定温室气体排放源至关重要。本文提出了一种混合的多准则决策方法，该方法结合了层次分析法和排序优先技术与理想解的相似性，并将此方法与确定温室气体排放源风险优先级的实际数据进行了比较。为此，使用六温室气体源和三温室气体（CO ₂，CH _4， N _2）的25年历史数据O）被考虑。因此，发现虽然焚烧废物造成的温室气体排放量最小，而能源部门却造成了最大的温室气体排放量。本文的结果表明，这种混合方法的使用简单易懂，并且具有很好的潜力来分类温室气体排放源的风险优先级。
