Is Plum good for ethical investors?

There are three funds (out of 36 total) labelled as ESG (environmental, social and governance) or ethical to choose from on Plum (for paid tiers only).

These three funds either apply exclusions, which remove ‘controversial’ investments such as fossil fuel or tobacco companies, or set ESG criteria which companies must meet to be included.

You can’t invest in any funds that are designed to create a positive impact.
