This is a really intresting idea and definitely a big, worthwhile problem.

One thing I'm curious about is how do you expect the economics of a green-fund to work? There's a handful of issues I see with this model:

1. ETFs/trackers are commoditized at the moment and, in a lot of cases, the broad, market-tracking funds are subsidised by more niche products offered by the same provider. 2. From a voting perspective, this only really makes sense at a truly massive scale. Even to get something like 0.1% of each company in S&P500, you need 24 billion AUM - and I doubt a 10bps shareholder can hold much sway, even when actively campaining around AUMs.

So, you need to be really big to have impact (assuming you follow S&P weightings), but you're competing in a highly comoditized space.

I'm sorry if I sound negative, I do hope this works out! I'm really curious to see how you plan on working around the issues I see in the space.
