A one-day tutorial on 11 May will present a broad overview of aviation greenhouse gas emissions (GHG) and familiarize participants with the vocabulary and concepts used in the description, measurement, regulation, and management of aviation GHG emissions. The third ICAO Environmental Colloquium (the second was held in May 2007) will be entirely dedicated to aviation and climate change. 

It will focus on strategies and programs of ICAO, industry, academic/research institutions and international organizations to harness technological, scientific and economic solutions in the global fight against climate change. This Colloquium, in English only, will provide a forum on aviation and climate change, in particular on related key developments emanating from the ICAO's Conference on Aviation and Alternative Fuels, UNFCCC COP/15 and the 8th Meeting of ICAO’s Committee for Aviation Environmental Protection (CAEP). 

This event will allow representatives from different stakeholders to share information on aviation and climate change with a view to facilitating environment-related discussions and high-level decision-making at the 37th Session of the ICAO Assembly. A tutorial will precede the Environmental Colloquium and will provide a broad overview of aviation greenhouse gas emissions (GHG) sufficient to familiarize participants with the vocabulary and concepts used in the description, measurement, regulation, and management of aviation GHG emissions. It will prepare participants for the discussions and presentations that will occur over the following 3 days of the Colloquium.
