An air pollution reduction plan drafted by the ministry calls for giving financial incentives to local authorities in Vilnius, Kaunas, Klaipėda, Šiauliai and Panevėžys for restricting the movement of diesel cars in the cities or parts of them.
Vilnius' municipal administration director Povilas Poderskis told BNS that it is not clear why the ministry wants restrictions only on diesel cars.
"What's the main purpose of banning diesel cars, rather than all cars, including gasoline ones, from entering the cities or certain parts of them?" he asked.
Poderskis said that a ban on cars entering the city should be phased in over a period of time, adding that Vilnius' aughtoruities are currently looking at how to restrict transit traffic via the Old Town and the central part of the capital.
Panevezys Vice Mayor Aleksas Varna told BNS that the city's authorities plan to discuss the ministry's proposals.
"I think (the movement of diesel cars) could be restricted in the central part of the city. The best thing would be keep all cars off (the central part), but we need public transport," he said.
According to the official, Panevėžys is already thinking about how to restrict all traffic in the central part of the city.
Tomas Grigalevičius, spokesman for the mayor of Kaunas, told BNS that is too early to comment on the ministry's proposals.
The ministry's air pollution reduction plan also calls for offering financial incentives for people buying environment-friendly cars starting in 2021.
