Tallinn's free transportation initiative has won the city an award by a Swedish NGO, Planka.nu.
The award, founded in 2010, has been handed out to organisations, individuals or cities that have made a notable contribution to changing urban traffic policies towards the better.
"Tallinn has shown that there are alternatives to the current model of fee-/ticket-financed public transport which would also lead to great benefits from a climate and resource perspective," Anna Nygård of the award committee said in a statement.
The award will be presented to Tallinn officials during the city's transportation referendum held from March 19 to 25.
If passed, the law implementing free public transportation in Tallinn would become effective beginning in 2013, the city government has said.
