Alterntive Bank Schweiz, yes! As a bank they’re perfectly fine for my very basic daily needs and I find it reasonable to suppose that they might have some local positive impact by easing access to credit to realities which contribute to the society in certain positive ways (of course, a serious research would be needed to confirm if this is at all true and effective, also in comparison with cantonal banks etc.). But the fund doesn’t fit into this reasoning.
Thank you again for all your suggestions!
