The French laid down a marker. Last week they announced they were banning domestic flights that could be travelled by train in under two-and-a-half hours.
It is the first time any major global economy has blocked air travel on environmental grounds.
The policy was an idea that came from the French citizens’ council, a collective gathered by President Macron as a way of showing he was paying attention after the Gilets Jaunes protests.
And clearly France is really listening. While we tinker around in Britain and say ‘What if?’, the French shrug and say ‘Voila!’
To further shake their environmental tail feather at us all, the French are also now set to offer car owners a €2,500 trade-in on their old motors towards an E-bike. They’re not messing around.
The ticking environmental clock means that the time for pleasantries and hand wringing is over. And if the French example illustrates anything, it’s that the public, too, believe in change.
