航空公司在转向可持续燃料方面滞后,未达到碳减排目标。 Airlines lag in switching to sustainable fuels, falling short of carbon reduction goals.

运输和环境组织的一项研究表明,大多数航空公司没有迅速向可持续的喷气式燃料过渡,而这种燃料只占航空燃料使用量的1%。 A study by Transport and Environment shows that most airlines are not transitioning quickly enough to sustainable jet fuel, which makes up only 1% of aviation fuel use. 虽然法国-KLM航空公司等航空公司做出了重大努力,但87%的航空公司没有取得有意义的进展,原因是成本高和主要石油公司缺乏投资。 While some airlines like Air France-KLM have made significant efforts, 87% are not making meaningful progress due to high costs and lack of investment from major oil players. 这妨碍了实现减少碳排放的目标。 This hinders meeting carbon emission reduction targets.
