It’s to raise their Company Equality Index score so that the execrable Human Rights Campaign doesn’t tell institutional investors such as Black Rock and Vanguard not to buy in to Lego. It’s corporate blackmail, and frankly, the wokesters in the “C” suite go along with the nonsense. Lego doesn’t give a sh*t about your rugrats; they just want the money to keep coming.
If you buy low cost Vanguard index funds, ESG does not factor in the management of the fund. The fund has to buy the basket of securities that are in the index, in proportion to the market cap of the securities in the market. The fund manager does not have the discretion to favor or disfavor securities in the index.
As for managed funds, the fund managers can use discretion.
Vanguard has both ESG and non ESG funds. Customers who do not wish to invest using ESG principles can purchase index funds which do not use ESG as a criteria.
