The object of the project is to acquire 23 fully barrier-free and low-floor articulated buses with natural gas propulsion that meets the EURO 6 emission standard, which will replace diesel buses of lower emission classes EURO 2 (12 cars), EURO 3 (5 cars) and EURO 4 (6 vehicles). CNG buses will be deployed on all bus routes operated by the applicant in the territory of the city of Brno and in the area of interest. The implementation of the project will result in a decrease in emissions by 10.507 tonnes per year.
