The “Aviation Emissions Cost Assessment 2008”, which focuses on climate change impacts, was published in July 2008. This research does not attempt to identify the impacts of ‘holiday flights’ separately from other flights.

A list of the current values for external costs used in transport appraisal is also available in DfT's online Transport Analysis Guidance ‘Webtag’:
