Plane flying far away with large contrails


The global aviation industry generated approximately one billion tonnes of CO2 in 2019 – a major contributor to climate impact, alongside warming from plane contrails. Yet, reducing  impact is challenging due to the sector’s fast rate of growth and a lack of ready zero-carbon alternatives.  

With many possible mitigation ideas, how does the sector choose which are best to develop? 

Professor Andreas W. Schäfer will review the role that integrated assessment models can have in deciding which outcomes best reduce the aviation sector’s climate impact.
