我们估算了日本两大航空公司（日本航空公司和全日空航空公司）的4万多个国际航班产生的二氧化碳排放量，并使用2005年至2015年期间进行的指数分解分析确定了这些二氧化碳排放的驱动因素。结果表明，引进更省油的波音787使两家公司减少了130万吨的二氧化碳排放量。然而，这些减少被航空公司运营的航班总数和每位乘客的距离所抵消。我们的结论是，引入具有更好燃油效率的绿色飞机的环境和商业战略不足以减轻飞机排放对气候的影响。
We estimated the CO(2)emissions produced by more than 40 000 international flights associated with Japan's two major airlines (Japan Airlines and All Nippon Airways), and identified the drivers for these CO(2)emissions using an index decomposition analysis conducted between 2005 and 2015. The results showed that introducing the more fuel-efficient Boeing 787 led to CO(2)emission reductions of 1.3 million tons by the two companies. However, these reductions were canceled out by the total number of flights and distances per passenger attributable to the airlines' operations. We conclude that the environmental and business strategy of introducing greener aircraft with better fuel efficiency was insufficient for mitigating aircraft emissions' effects on climate.
