国际清洁交通委员会（ICCT）：航空愿景2050：迈向气候中和增长的潜力研究报告（英文版）

Aviation is a growing contributor to climate change, with effects extending beyond carbon dioxide (CO2) emissions to include short-lived climate pollutants (SLCPs) such as nitrogen oxides, black carbon, and contrail cirrus. In 2022, the International Civil Aviation Organization agreed to achieve net-zero CO2 emissions by 2050, but the industry is not on track to deliver the scale of fuel efficiency improvements, sustainable aviation fuel (SAF) uptake, and zero-emission aircraft developme
