◇汽、柴油車的油耗值 ≠ 碳排放量
相信很多鄉民都知道消耗每公升汽油的CO2排碳量會比柴油少了20%。
根據中油網站的資料,消耗每公升汽油會排放CO2約2.24公斤,柴油約2.7公斤。
如果某輛汽油車的油耗是柴油車的83%,它們就會有相同的碳排放量。
換句話說,如果某輛汽油車的油耗是14.0km/L,那它的碳排放量相當於柴油車16.8km/L

而根據道路實測,現在很多汽油車也越來越省油低碳排放了。
柴油車實際的碳排放量不一定比汽油車少。
以下是汽、柴油車碳排放量相同的一個例子,
這兩台汽、柴油車的實際油耗比較,他們相同車系,馬力相同,而且碳排放量也很相近
引用的資料是英國True MPG資料庫的真實油耗數據,這是英國What Car雜誌多年來
長期進行道路實測,他們累積很多各大汽車品牌車型的真實油耗數據。
七代 Golf 1.2TSI vs Golf 1.6TDI,兩台車的馬力一樣。
真實油耗為 1.2TSI 18.3km/L,1.6TDI是 21.5km/L,
雙方的油耗相差15%,所以汽油Golf 1.2TSI的碳排放量與Golf 1.6TDI柴油幾乎相同。
另外值得注意的是,跟官方的NEDC油耗值相比,汽、柴油車的真實油耗分別有不同降幅
汽油Golf 1.2TSI的真實油耗只比官方NEDC測試值少了25%,
但Golf 1.6TDI柴油的實際油耗卻比官方數據少了32%,
這也顯示1.6TDI在實驗室和真實道路油耗的差距比較大,實驗室油耗值灌水比較多。

塞車程度,中下。

可以看到某compact中小型汽油車的碳排放量跟另外三台小型家庭柴油車在伯仲之間。
而且它的NOx排放量還低了17~25倍。
