        為應對全球氣候變化 航空業加強減排技術開發

        2019年06月10日 09:59 來源:中國新聞網 參與互動 

          中新網6月10日電 據外媒9日報道,面對氣候變化和溫室效應,全球各航空公司雖然有意愿進行節能減排,但業界人士指出,能大量減少航空業溫室氣體排放量的科技目前仍有待開發。

          根據歐洲環保署(EEA)的數據,每人搭飛機飛行1公里會排放285克的二氧化碳,是所有交通工具中,單位距離碳排量最高者。相較之下,公路運輸每1公里路程的碳排量是158克,鐵路運輸為14克。

          據報道,為因應全球變暖危機,航空業已承諾,在2009至2020年期間,每年將提高燃油效率1.5%,并在2050年達到二氧化碳排放量比2005年減少50%的目標。

          目前,航空業已經開始投資建造擁有升級版發動機的低污染飛機,此種發動機將調整空氣動力學特性、使用重量較輕的裝置。此外,部分航空公司已著手試驗生物質燃料的實用性,但生產成本仍偏高。至于電動發動機,專家認為,未來20年內恐仍無法進入商業使用。

          巴黎波士頓顧問公司的副主任普魯維耶指出,降低碳排量的重要方法是“持續更新機隊”。據悉,最新大型客機已可減少20%至25%的碳排量。不過,這只能解決約30%的問題。

          國際民航組織指出,改善空中交通管理也有助減少溫室氣體排放量,而新一代燃油效率較高的機型預計在5至10年內可以問世。
