Deutsche Umwelthilfe (DUH) refuses to disclose 15 major donations from 2021. Of 17 donations and gifts with a volume of more than €20,000 that the organization received in 2021, it only named the donors for two items. In the case of 15 donations with a total volume of €1.5 million, DUH refuses to be transparent and does not provide any information on the donors. This emerges from the lobby register of the German Bundestag.
