The CO2 emission presented in the scenario studies and in the simulation tool refer to the CO2 emission of a standalone greenhouse and according to the definition of EU ETS. This means that CO2 emissions from the public grid are associated with fossil fuel power plants and therefore do not contribute to the emission of the greenhouse. External CO2 used for CO2 fertilization and which is not produced on-company is treated in the same way, meaning that the related emission is associated to the supplying industries. Because the fixated CO2 by the crop is regarded as “Short-cycle CO2" and is released into the atmosphere relatively quickly after being captured, this is also not into account.
