PARIS, France: French lawmakers are expected to approve a ban on any domestic flight that can be covered by train in under 2.5 hours.
The bill is part of a government program to lower carbon emissions by 40 percent by 2030.
France has a comprehensive high-speed rail system, and is continuing to construct new lines.
The bill is expected to reach the Senate, where it is supported by President Emmanuel Macron's ruling party.
The French government expects airlines to comply with the law. Last week the government approved $4.7 billion in support to Air France, following the $12.3 billion in government aid it received last year.
Of note, wrote the Air Journal, the 2.5-hour rule would eliminate only five domestic routes: Paris-Bordeaux, Paris-Lyon, Paris-Nantes, Paris-Rennes, and Lyon-Marseille "representing a total of 12% of passenger traffic and 3.5% of CO2 emissions from air travel in France."
"We know that aviation is a contributor of carbon dioxide and that because of climate change we must reduce emissions.
Equally, we must support our companies and not let them fall by the wayside," said Industry Minister Agnes Pannier-Runacher, as reported by Europe 1 radio.
