A computer-implemented method for establishing at least one low or zero emission traffic zone and for controlling and monitoring a dynamically operated drivetrain of hybrid vehicles passing through the at least one established low or zero emission traffic zone is provided. The method includes: acquiring data from air quality-sensitive sensors placed within a region including the at least one low or zero emission traffic zone to be established; operating a cloud-based service for evaluating the acquired data regarding air quality; wirelessly transmitting signals representative of a location and a shape of the at least one low or zero emission traffic zone to hybrid vehicles; operating vehicle-based mode transition means for at least initiating a change of a drivetrain mode of the hybrid vehicle to electric mode; generating a blockchain data block including data regarding the current position and the dynamically operated drivetrain of the hybrid vehicle; and adding the generated blockchain data block to a blockchain residing in a blockchain system.
