it is time for me to walk the walk and change funds

We all should do this, although it is going to get very hard as investments in fossil fuels (and all other investments) are highly concentrated.

For example, the world’s 2 biggest asset managers, Vanguard and Black Rock, account for 17% of all global investments in fossil fuels. 50% of the total institutional investments in fossil fuel companies are held by just 23 investors. One new study is here.

The same two AMs -Vanguard and Black Rock- are also the two biggest shareholders of Google, Amazon, Facebook parent Meta, Apple, and Microsoft, as well as many other multinationals across practically all industry sectors.

The concentration in the asset management industry has increasingly become concerning and appears to have accelerated since the financial crisis 2007/08 for various reasons (e.g., there’s a growing trend to passively managed portfolios, which is basically a good thing imo, but it puts AM’s fees under pressure, which is why they further concentrate, which in turn increases asset price volatility, which also means higher systematic risks, …).
