​Description:

The Impacts and Science Group (ISG) was formed in the CAEP/8 meeting (2010). Its role is to provide the best possible consensus information from the science community to CAEP on aviation's impacts on climate, air quality and noise issues.

Current work:

• Analysis on fuel composition and its effect on local air quality and climate
• Analysis on the air quality and climate impacts of NOx emissions, including interdependencies
• Assessment of contrails, aviation induced cloudiness and aerosol-cloud interactions associated with aviation emissions.

Main publications:

• White paper on Air quality and climate impacts interdependencies and trade-offs of aviation emissions (2025)
• White paper on Contrail science workshop report (2025)
• White paper on Update on understanding of potential impacts of supersonic aircraft (2025)
• White paper on aviation noise impacts, State of the Science 2019 (ICAO Environmental Report, 2019)
• White paper on aviation noise impacts (ICAO Environmental Report 2016, Page 30)
• White paper on aviation and Climate (ICAO Environmental Report 2016, Page 99)
