At the beginning of 2025, Sofia Municipality introduced the "Green Ticket" for public transport in Sofia four times as a preventive measure against air pollution caused by fine particulate matter. On days with potential air pollution, the municipality encourages drivers to leave their cars in free buffer parking areas and use the eco-ticket costing just BGN 1. The ticket is valid for the entire public transport network for the whole day.
