Method for determining actual emission value of vehicle

The invention relates to a method for determining an actual emission value of a vehicle (120), the method comprising: receiving (112) a certificate file from a supply point (110) providing an energy carrier or power loaded during a charging or refueling process in the vehicle (120), the certificate file comprises information about emission related to the production of the energy carrier or the electric power; the certificate file is stored together with at least one piece of information about the amount of power or the amount of energy carrier loaded. Then, by means of the information in the certificate file, the actual emission of the travel route can be calculated. 本发明涉及一种用于确定车辆(120)的实际排放值的方法，所述方法包括：从提供在车辆(120)中的充电或加油过程期间加载的能源载体或加载的电力的供应点(110)接收(112)证书文件，所述证书文件包括关于所述能源载体或所述电力的生产相关的排放的信息；而且将所述证书文件与关于所加载的电力量或能源载体量的至少一个信息一起存储。接着，借助于在所述证书文件中的信息，可以计算行驶路线的实际排放。
