Assessing Current Scientific Knowledge, Uncertainties and Gaps in Quantifying Climate Change, Noise and Air Quality Aviation Impacts

摘要

During the 7th Meeting of the International Civil Aviation Organization (ICAO) Committee on Aviation Environmental Protection (CAEP), held in Montreal, Canada in February 2007, CAEP members and observers agreed that a scientific workshop would be organized to assess the state of knowledge and gaps in understanding and estimating noise, air quality and climate impacts of aviation. The CAEP agreed that a small group would be formed to plan and execute the workshop, facilitated by the CAEP Secretariat. This should include carefully crafting the questions posed to the science community in order to best inform CAEP. The Workshop on Assessing Current Scientific Knowledge, Uncertainties and Gaps in Quantifying Climate Change, Noise and Air Quality Aviation Impacts (hereafter referred to as the Impacts Workshop) was held in Montreal, Canada at ICAO Headquarters, 2931 October 2007. It was structured along the lines of panels in three subject areas: noise, air quality and climate impacts of aviation. The experts from each area were also involved in discussion on all issues associated with trade-offs and interdependencies among these impacts. The panels were reconstituted during the last breakout session to comprise experts from all subject areas in order to facilitate the interdependencies and trade-offs discussions. The objective of the workshop was to critically reviewknowledge and methodological requirements important to the comprehensive evaluation of aviation environmental impacts in a decision-making context.
