The study, ‘Trends in Global Noise and Emissions from Commercial Aviation 2000-2025’, says CO2 emissions from aviation will rise from its current level of 670 million tonnes to 1.48 billion tonnes by 2025. If the 1.48bt figure for CO2 is reached, it will represent the worst case scenario outlined by the Intergovernmental Panel on Climate Change.

除了CO2数据之外，该报告还突出显示氮氧化物的问题和飞机噪声的问题。NOx from planes is expected to rise from 2.5mt in 2000 to 6.1mt in 2025, and the number of people ‘seriously affected’ by aircraft noise will rise from 24m in 2000 to 30.3m by 2025. The authors do not deny there will be cleaner and quieter aircraft, but the expected increase in air traffic will more than wipe out the gains.

目前尚不清楚为什么报告尚未发布。它被提供给去年的美国/欧洲空中交通管理研讨会;它从未形成过正式诉讼的一部分，但在研讨会的网站上列出。

它由四个政府资助的研究机构编写，包括EuroControl和美国交通部。188金宝搏bet官网下载它的目的是将各种建模机制汇集在一起​​，以锻炼航空的长期影响，并且在许多方面，它只是确认现有数据，尽管在规模的更加悲观的结束方面也是非常悲观的。
