Some long-haul flights connecting Europe and Asia are emitting 40% more CO₂ since the Russian invasion of Ukraine in February 2022, my new study shows. The spike is largely due to airspace closures above conflict zones which are forcing airlines to seek alternative routes, significantly increasing flight times. Longer flights consume more fuel and increase the operating costs for airlines, quite apart from their contribution to climate change.
The research I led with colleagues highlights how conflicts contribute to climate change in unexpected ways. Understanding this is crucial for tackling aviation’s environmental footprint.
