The GHG quota is a regulatory instrument for reducing CO2 emissions in the transport sector. CO2 savings are realised through the use of eMobility, which can then be sold to the mineral oil companies that are subject to the quota. Thus, additional costs arise for the mineral oil companies, and users of eMobility (which is far lower in CO2 emissions by comparison) generate additional income. This redistribution has a steering effect that is intended to ensure the transition from conventionally powered vehicles to eMobility in the long term.
