BRUSSELS, Sept 4 (Reuters Breakingviews) – Short flights within Europe are frequent flyers on wish lists of things to ban. In the name of cutting carbon dioxide emissions, countries from Germany to Spain are proposing to prevent brief air trips, and lobbyists like Greenpeace say governments should require travellers to choose trains or other ground transport for shorter journeys. But not all short flights are alike, and banning commercial hops makes less sense than targeting private jets.

In 2022 aviation emitted 800 million metric tons of CO2, around 10% of the world’s 8 billion tons of CO2 emitted annually by various means of transport, according to the International Energy Agency. In the same year European Union emissions were around 2.5 billion tons and in the recent past flying has contributed about 4%. But most of that is long-haul flights. A 2022 study of 31 European countries found that flights shorter than 500 km account for 28% of departures, but under 6% of fuel burnt.

Commercial jets do pollute more than ground transit, but they also have advantages that can’t be easily matched. To avoid a disproportionate impact on disabled passengers and others en route to more distant destinations, train services need to catch up first. Denying a short flight to connecting passengers could just send them to their cars, according to KLM CEO Marjan Rintel.

Limiting private jet travel would make a bigger difference, with fewer broad-based disruptions. Private jets have a far bigger impact per passenger on the environment than their flying-bus counterparts: as much as 45 times the amount of emissions per passenger, according to the Institute for Policy Studies. Greenpeace data shows that private jet flights in Europe put out 3.4 million tons of CO2 in 2022, twice 2021 levels, and mostly on flights with a range of less than 750 km.

Short-haul bans are especially beside the point when they look more like industrial policy than climate action. In France, where domestic connections are already prohibited for journeys of under two and a half hours, only three routes were actually banned, with projected savings of just 55,000 tons of carbon dioxide output per year. Shuttering unprofitable routes and prohibiting new competition on those legs acted more like a leg-up for Air France’s business plan, according to Davy transport analyst Stephen Furlong.

In any case, there’s a positive non-climate economic case for short-haul flights. They have allowed upstart carriers like Norwegian Air to challenge legacy airlines and rebuild after the pandemic. Connecting flights also make it possible for Brussels Airlines to serve as a hub for passengers in and out of Africa, a lifeline for countries whose livelihoods depend on travel routes.

There’s a case for phasing out shorter flights over time, and for surcharges like Belgium’s 10 euro tax on flights of less than 500 km. But banning brief mass-transit trips now is a hop too far.

CONTEXT NEWS

Countries such as France, Spain, Belgium and Germany have enacted or are considering measures to reduce or ban short flights. The European Union’s long-term mobility plan calls for discouraging plane travel where lower-impact alternatives exist.

Direct emissions from aviation accounted for 3.8% of the EU’s total carbon dioxide emissions in 2017, according to the European Commission. Aviation is responsible for 14% of transportation-sector emissions.

Greenpeace research found that the number of European private jet flights jumped from 118,756 in 2020 to 572,806 in 2022, with carbon dioxide emissions going from about 355,000 metric tons to 3.4 million tons over the same period. More than half of 2022 private jet travel was for distances of less than 750 km.
