Thanks to an initiative by the citizens of Sofia, called Green Rails in Sofia, grass was planted by the Municipality on a an area of newly reconstructed tram line in Sofia. The cited benefits were heat reduction, noise reduction, aesthetics, natural water retention and drainage, and lower costs of maintenance in the long term compared to grey alternatives. The grassroots initiative “Green Rails in Sofia” are determined to keep putting pressure on the local authority to continue planting grass on other parts of the tram lines. (Ref. 1; Ref. 2; Ref. 3)

Details on the roles of the organisations involved in the project

The coordinator of the citizen group Green Rails in Sofia knew that green rails were widespread in a number of other cities in Europe. As a result, when he heard that the tram line would be reconstructed around the Russian Monument Square, he created the Green Rails in Sofia initiative to pressure the local authority to implement the project. The pressure was successful and the municipality implemented the intervention (Ref. 1; Ref. 4).
