Abstract

Many studies consider substitution of aircraft services with high-speed train (HST) services on short-haul routes desirable for environmental reasons. This paper empirically examines this perception by evaluating local air pollution (LAP) and climate change impacts from a flight and an HST service between London and Paris. Comparing the emissions, the impact, and the cost of damage from the aircraft journey with the HST journey, it was found that substituting an aircraft seat with an HST seat is beneficial. These benefits are likely to occur on all routes on which aircraft and HST substitution will likely occur. In spite of any limitations in the evaluation of environmental impact, the analysis suggests that such an evaluation is valuable and provides important information.
