Selected environmental data of the Volkswagen Group are presented here in aggregate form. The data are determined, checked and released to the production locations on the basis of a group-internal standard (VW standard 98 000). In order to increase the degree of precision and the consistency of the information gained, the gathering of the environment-relevant consumption and emission data is subject to a continuous improvement process. This applies in particular to that information that has to be determined with the aid of special calculation algorithms. Furthermore, the values for the December of the past year can contain an estimated portion if for instance it is based on settlements from energy suppliers or waste removers, that at the time of the data gathering were not available. These estimated portions will be replaced at the next data collection by the then known December values.
