[4] From June 2017 until his resignation on 19 February 2024 he was also a member of the investment committee for the EUR 24 billion German Sovereign Wealth Fund KENFO.

In 1993, Jochen Wermuth became an EU-TACIS adviser to Russia's Ministry of Finance in the area of "fiscal policy framework development" based on his studies of the transformations following German unification.

[20] The German newspaper Die Tageszeitung (taz) argued that while it may happen to be a sympathetic cause for someone to make a donation to support green causes, what if someone had provided a 30 percent boost to the election campaign budget for some party promoting coal production?

"[26] On the 19th of June 2017, Jochen Wermuth was appointed as an investment committee member of the newly established Fund for the Financing of Nuclear Waste Management (Fonds zur Finanzierung der kerntechnischen Entsorgung).

The commentary discusses climate change and the impact monetary investments can have in reducing its adverse effects while also reflecting positively on one’s wealth.

[30] In 2020 he appeared in the movie “Schmutzige Geschäfte mit unserer Rente”, where he presented Nexwafe, a German solar wafer manufacturer.

[31] He first got known to the general public when German TV station Suedwestfunk did a documentary about his work in the Russian Ministry of Finance "Der Taschenrechner des Kreml, 1997".

[38] Jochen Wermuth is a sponsor of Greenpeace since 1992,[39] a member of "Eurosolar"[39] since 2000 and did his first investments into clean tech in 2000, starting with an integrated production chain from quartz sands to mono-silicon with the late Nobel Prize Laureate Alexander Prokhorov.

He found that he required a stronger balance sheet to see through such important break-through technologies, turned his family office into an investment advisory business and gradually built the team and assets dedicated to investments in sustainable growth, culminating in the "Green Gateway Fund"[40][41][42][43][44] dedicated to investing in leading EU clean tech companies [45] with technologies relevant to the Russian-Kazakhstan-Belarusian Free Trade zone to which entry to such a market via Russia's region of Tatarstan might be attractive.

[46][47] After leaving Deutsche Bank, Wermuth founded his own family office focusing on sustainable investments, Russia and the CIS.

[48] Wermuth Asset Management (WAM) is an international investment advisory firm headquartered in Germany and with branches in Russia and the Netherlands.

WAM has been a member of the World Economic Forum's "Champions of Tomorrow" and the G20 Green Growth Action Alliance (G2A2) initiatives and a sponsor of Transparency International[51] and of the "Deutsch-Russische Jugendaustausch" (German Russian Youth Exchange).
