ABSTRACT

Civil aviation is one of the drivers of global growth. It increases at around 4.4% per annum and is poised to maintain this growth for the next 20 decades. On the other hand, aviation is responsible for 5% of total anthropogenic radiative forcing and is expected to increase substantially in the future. In the face of the continuing expansion of air traffic, mitigation of aviation’s climate impact becomes challenging but imperative.

 

Effective mitigation strategies should address both CO2 emissions (<50% of the overall climate impact of aviation) and non-CO2 effects from NOx, H2O, contrails, and particulates. CO2 emissions have a long lifetime of centuries; therefore, the CO2 effects mainly depend on its emission quantity. A low emission system will be beneficial in reducing the warming effects from CO2 emissions. In comparison, the non-CO2 effects have a strong temporal and spatial dependency, making it possible to reduce the non-CO2 effects via operations, e.g., by avoiding the so-called climate-sensitive regions. This presentation will provide examples of how technological and operational measures can coherently reduce the climate impact of aviation.
