Concept of climate-charged airspaces: a potential policy instrument for internalizing aviation's climate impact of non-CO₂ effects

Approximately 50–75% of aviation's climate impact is caused by non-CO₂ effects, like the production of ozone and the formation of contrail cirrus clouds, which can be effectively prevented by re-routing flights around highly climate-sensitive areas. Here, we discuss options how to incentivize re-routing approaches and apply...
