Around 800,000 heat pumps are now installed in Germany. As a result, the demand for electricity for heating is growing. If the heat pumps are not operated with green electricity, this causes CO2 emissions. "Heat pumps can end up causing even more CO2 than modern natural gas or oil heating systems if they are not efficient," explains Florian Henle, managing director of the eco-energy supplier Polarstern.

The market for green heat pump tariffs is still in its infancy. It is true that the majority of heat pump tariffs are sold as green electricity. However, it is doubtful whether this is really green electricity or simply coal and nuclear power colored green by purchased eco-certificates. The Green Electricity Label provides a remedy here.

The green electricity label ensures that green electricity is really being purchased and that the energy supplier is investing in the energy transition, for example by expanding wind and solar plants or implementing tenant electricity projects. In total, more than 1,300 energy transition projects have already been implemented and co-financed. Consumers who use heat pump tariffs with the Green Electricity Label, such as Polarstern's 'Really Green Electricity', can therefore be sure that they are saving CO2 emissions and promoting the energy transition with their electricity purchases.
