Abstract: This overview paper describes the impact of aviation on the environment and its effects on climate change. It provides scientific and decision-making elements for considering the environmental impact of air travel, especially at universities. Travelling is an essential part of international cooperation and as air traffic constitutes the only means of travelling long distances within reasonable timeframe, corporate air travel remains indispensable. However, assessing the contribution of air travel to human induced global warming is characterized by large uncertainties, mostly due to non-CO2 emissions of airplanes and direct and indirect impact on the radiative balance. A recommendation for a uniform so-called “emission weighting factor” (EWF) of 3.0 is made for reporting, as it is believed to best represent the actual current impact of corporate air travel’s CO2 and non-CO2 emissions on the environment, with the suggestion that it be regularly reassessed.
