Ban will affect private diesel vehicles in Rome's historic centre.
Rome will prohibit private diesel vehicles from circulating within the city's historic centre from 2024, mayor Virginia Raggi said on 27 February.
Raggi announced the move at the C40 Women for Climate meeting in Mexico which she left early to return to deal with Rome's snow crisis.
Addressing the summit in fluent English, Raggi said "energetic" measures were required to protect the environment and that "we must have courage to take vigorous action."
The diesel ban was welcomed by environmentalist organisations such as Greenpeace Italy however opposition politicians pointed out that the mayor was "forgetting" about the city's roughly 1,500 diesel-run public buses. The ban is also not expected to affect the diesel-run delivery trucks that operate throughout the historic centre on a daily basis.
Since taking office in June 2016 Raggi has made several radical transport suggestions for Rome, from
cable cars to
new tramlines.
