What are CO₂ certificates?

CO₂ certificates represent the amount of emissions that are offset. A certificate corresponds to one ton of greenhouse gases.


The amount of greenhouse gas emissions that are reduced or avoided through a climate protection project are calculated as follows: For power production with renewable energies, the amount calculated is the amount of greenhouse gas emissions that the climate protection project reduces or avoids.

Furthermore, a scenario is described that highlights the greenhouse gas emissions that would have been created without the climate protection project. This scenario is referred to as a baseline. The difference between the baseline emissions (reference case emissions) and the expected project emissions provide the expected reduction in emissions.

CO₂ emissions from the production of products and services that cannot be reduced, can be offset through the purchase of CO₂ certificates, which in turn makes them climate neutral. For this purpose, CO₂ certificates are sold in the accordant amount and subsequently cancelled. This cancellation confirms verifiability that the certificate’s owner has performed carbon offsetting measures.
