One way to convert the current reference to CO2-neutrality is to purchase certificates of certified green electricity. These certificates are designed to ensure that the electricity is 100% from renewable energy sources, and the expansion of this is supported with the purchase. The certificates are regarded as a kind of seal of quality which is only awarded under certain conditions. However, there are different types of certificates on the market, the quality of which is determined by the provider.
If one chooses this type of CO2 neutralization, the environmental benefits and thus the countervailability are an important criterion. This includes ensuring the environmental benefits, the origin of the green electricity and the renewable energy projects that are supported. The “RenewablePlus” and the “OK-Power” seal are certificates that have been accepted in the market.
Of course, there are also always critical comments on this type of CO2 neutralization. However, their countervailability is not given by the establishment of high-quality labels. In the end, the purchase of certified green electricity compared to other possibilities is a relatively inexpensive way to make the current reference CO2-neutral. Recognised certificates are traded between 0.07 ct/kwh and 0.13 ct/kwh. The pool purchasing of larger quantities will generate price advantages. In addition, the costs for the companies are manageable.
