2009年至2019年,全球旅游业排放量猛增40%,占世界总量的8.8%,超过了经济增长的速度。 Global tourism emissions surged 40% to 8.8% of world total from 2009-2019, outpacing economic growth.

最近的研究显示,全球旅游业的碳足迹正在以全球经济的两倍的速度增长。 Recent research shows that the global tourism industry's carbon footprint is growing at twice the rate of the global economy. 2009年至2019年间,旅游业的排放量增加了40%,占全球总排放量的8.8%。 Between 2009 and 2019, tourism emissions increased by 40% to 8.8% of total global emissions. 前20个最大的国家,包括美国、中国和印度,对这些排放量大多负有责任。 The top 20 countries, including the US, China, and India, are responsible for most of these emissions. 航空和运输是关键的贡献者,研究报告建议采取一些措施,如减少长途航班和征收碳税,帮助降低排放量。 Aviation and transportation are key contributors, and the study suggests measures like reducing long-haul flights and implementing carbon taxes to help lower emissions.
