Every financial product (shares) I have found is greenwashing, especially in the financial sectors. As an example:

A: We plant one tree for each tree we chop down!
B: Don't hardwood trees take a long time to grow?
A: Yes, so we plant a different species that grows faster!
B: So it's the wrong food for the animals and it still takes ages to grow?
A: Ha, yes, that's the best the market will do though, we are the most ecological company. It makes new habitat.
B: Are the trees in the same place as the ones that were chopped down?
A: No, they are hundreds of miles away.
B: So it's a bit similar to me demolishing a bit of your house and building (very slowly) a replacement hundreds of miles away where you had no access to food and every other thing you need?
A: Yes.
