Sometimes what is not said is stronger than the spoken word.

It is quite remarkable that the Deutsche Bank CEO Christian Sewing simply ignores a specific question about DWS and the charge of greenwashing by the Deutsche Bank subsidiary and praises the general course of his own company.

Perhaps Sewing is not allowed to comment on the allegations of the former DWS sustainability boss for legal reasons.

The problem of greenwashing, however, is so elementary in the entire sustainability discussion that everyone in the financial industry must seize every opportunity to condemn the possibility of green painting and to identify the dangers. Nobody has to think that the newly discovered love of sustainability is only driven by saving the world. “That's not our job either,” Blackrock boss Larry Fink said in an interview with the FAZ.

No, it is not, but the financial industry has been under close scrutiny since the financial crisis that helped cause it. For many years, the banking industry had a credibility problem from which it can gradually get rid of - also with the help of the business community towards more climate protection. If the financial sector fails to credibly communicate a zero tolerance policy on greenwashing, everyone will be thrown back.
