Desiree Fixler is one of the most influential and candid voices in sustainable finance — a former ESG champion from within the industry who became one of its most rigorous critics. As Group Sustainability Officer at Deutsche Bank's asset manager DWS, she exposed what she regarded as material greenwashing: significant gaps between the firm's public ESG claims and its internal reality. When her concerns and her role were dismissed, she went public — and the resulting investigations by US and German authorities triggered a dramatic chain of events, including a police raid, the removal of top executives, and landmark greenwashing penalties. Her action sent shockwaves through the finance industry and helped catalyze global efforts to tackle greenwashing.
With more than 25 years in sustainable finance and investment banking, Fixler held senior roles at JP Morgan, Deutsche Bank, and Zais Group, and helped develop market-transforming products including the iTraxx and CDX indices. A graduate of the London School of Economics, she now advises financial institutions and regulators — including the UK's Financial Conduct Authority and the Monetary Authority of Singapore — sits on the CFA's ESG Technical Committee and the WEF's Global Future Council on Responsible Investing, and guest lectures at Cambridge. She brings rare insider authority to the question that now defines sustainable finance: how to separate genuine impact from expensive theater.
