Greenpeace militants on Monday draped a giant banner from a Deutsche Bank tower here calling for more development and climate protection funds.
"If the world were a bank it would been saved long ago," read the yellow banner on one of the bank's two gray glass towers, which are being renovated.
The banner was hung to call for "more financial commitment by the government to international climate protection," a statement on Greenpeace's German website said.
Deutsche Bank's towers "symbolise all the German banks that have received billions in financial support from the government," the statement said, even though the biggest German bank has not itself asked for aid.
Property lending specialist Hypo Real Estate has received 102 billion euros (132 billion dollars) in loan guarantees, the environmental group pointed out.
"The climate crisis and the economic crisis can be solved together," it said.
"It is now time for a massive investment program in green technology, a green New Deal," the statement quoted Greenpeace climate specialist Karsten Smid as saying.
The New Deal was an economic programme implemented by US president Franklin D. Roosevelt to pull the United States out of the Great Depression.
The banner, 169 square meters (200 square yards) according to Greenpeace, was hung five floors from the top of the tower, around 140 metres (yards) above the heart of Germany's financial centre in Frankfurt.
Germany has created a banking sector stabilisation fund known as SoFFin, which has a total of 400 billion euros in guarantees and 80 billion euros in cash to support the crisis-hit banking sector.
"Greenpeace calculates that industrialised countries should provide at least 110 billion euros per year to effectively limit greenhouse gases worldwide," the statement said.
