Asset manager DWS, mostly owned by Deutsche Bank, has drawn attention from regulators and activists over "greenwashing" allegations.

Greenpeace activists scaled Deutsche Bank’s headquarters in Frankfurt Wednesday and strung up a large yellow banner to protest against the climate investment policies of the German lender and its asset management company DWS.

The action came a day ahead of the annual shareholder meeting of DWS, which is mostly owned by Deutsche Bank and has drawn attention from activists and regulators over allegations it misled investors about “green” investments. DWS has disputed the claims.

Deutsche Bank (DB) said sustainability and climate protection were “strategic priorities,” and that it supports DWS in the development of its sustainability policies and standards.

The German-language Greenpeace banner was unfurled shortly after 6 a.m. local time (midnight ET) and stretched across part of the glass facade on the lower section of Deutsche Bank’s twin office towers. The banner translated as “Force DWS [to] protect the climate!”

The event drew a half dozen police vehicles, but an officer said there would be no arrests.
