以上數字以政府間氣候變化專門委員會《第五次評估報告》提供的「全球變暖潛能」數值計算，並會因應新蒐集到的數據/資訊而有所更新。
The above numbers were calculated using Global Warming Potential (GWP) values provided in the Fifth Assessment Report (AR5) of the
Intergovernmental Panel on Climate Change (IPCC) and may be subject to update based on the new data / information collected.
由於四捨五入關係，統計表內個別項目的數字加起來可能與總數略有出入。
There may be a slight discrepancy between the sum of individual items and the total as shown in the table owing to rounding.
數值以三個有效數字表示
Numbers are rounded to three significant figures
@ 「其它燃料耗用」包括在商業、工業及住宅中耗用的燃料
The “Other End Use of Fuel” includes the use of fuel for combustion in commercial, industrial and domestic premises
