Environmental Trends

The first ICAO Global Environmental Trends were presented and endorsed at the 37th Session of the ICAO Assembly (2010). Since then, updated global environment trends have been developed and presented to every Assembly Session to form the basis for their considerations and decisions on environmental matters. The establishment of the global environmental trends is crucial to the work of ICAO as it provides a robust single reference for sound discussion and decision-making.

 

The latest set of trends, including noise, local air quality (LAQ), and emissions that affect the global climate was delivered to the ICAO 40th Assembly (2019), as detailed in A40-WP/54


Current and previous trend assessments are provided in the following ICAO Assembly WPs:

 


Specific details on the trends for noise, LAQ and emissions that affect global climate are provided in the following pages:
