Such a tax could be imposed, but incentives for buying less polluting cars would have to be put in place as well, Deputy Finance Minister Loreta Maskaliovienė said on Wednesday.
"If we agree on two things, a tax plus incentives, we may table such a proposal, but there is no such agreement yet," she told the parliament's Committee on Budget and Finance.
Prime Minister Saulius Skvernelis said in August that the government might consider measures to encourage motorists to choose less-polluting vehicles, but added that it was not discussing a blanket tax on cars.
The parliament last spring did not back the government's proposal to tax second and further residential properties owned by one individual at a rate of 0.3 percent.
Skvernelis said in June that this was not a good time to impose such a property tax.
