AI Summary

Contrails from aircraft, though generated by a small portion of flights, add warming comparable to aviation’s CO₂ emissions. A new report from Klima Consulting, commissioned by T&E and authored by former IPCC scientist Olivier Boucher, quantifies this impact and suggests that eliminating contrails could prevent roughly a decade of climate warming attributable to aviation. The study highlights the potential climate benefit of targeting contrail formation as a mitigation strategy.
