The Helmholtz Centre for Environmental Research (Helmholtz-Zentrum für Umweltforschung or UFZ) covers Article Processing Charges (APCs) for affiliated corresponding authors who wish to publish in any Frontiers journal.
The UFZ is a participating member in an agreement for Open Access publishing between the Helmholtz Association (Helmholtz-Gemeinschaft Deutscher Forschungszentren) and Frontiers, and as part of this agreement a 10% discount will be applied to APCs for articles by UFZ-affiliated corresponding authors.
This discount is applied to the net APC, i.e. the APC, which would otherwise be payable after deduction of any other discounts that may apply.
Update 29/01/18: The discount rate has been changed to 15%.
