The Estonian government is planning a law amendment that would enable to use the pollution quota finances that have been left over from the contracts concluded so far to buy four new trams more from Spain, LETA/Public Broadcasting reports.

According to a procurement signed already, 16 new modern trams will be bought from Spain for revenues from selling excess pollution quota.

Money was gained for the purchase of additional 4 trams from residues of contracts concluded with Spain that emerged in connection with the change of investment plans, environment ministry spokeswoman Berit-Helena Lambi said.

The new trams, produced by the Spanish CAF company, will ride in the 3rd and 4th tram lines in Tallinn.

Before the new trams are introduced, the tramways of these lines will be reconstructed this and next year.

In addition to trams, three new city buses operated by natural gas will be bought and these go to Pärnu.
