Climate change and the focus on a sustainable economy are not just a marketing idea.
But this insight has not really caught on with some banks.
Instead of making big speeches to sell new financial products, the focus on concrete measures would be all the more necessary.
In their study presented on Wednesday, the banking supervisors of the European Central Bank (ECB) rightly warn banks against overly careless handling of climate and environmental risks.
The flood disaster in the Ahr Valley last year showed how much closer the dangers of climate change are.
Certainly it is currently still very difficult, if not impossible, to quantify the future dangers in many detailed questions.
Despite the imponderables, a lot of detailed work is now needed to better get the climate risks under control.
The dangers of climate change affect the core business of banks: the management of risks, especially credit risks.
These will be increasingly influenced by climate change in the future.
So it is high time to integrate the topic into all areas of a bank.
Because climate change not only endangers the economy, but the future of mankind.
The example of Deutsche Bank's investment company, DWS, clearly shows that aggressive marketing of sustainable financial investments can damage credibility.
