There are a number of "socially responsible" ETFs with quite low fees - not as low, but not bad. Most focus on environmental goals, though some have worker rights, "biblical values" or equality goals too, some also seek to derive most of their revenue from the renewable industry. That's definitely riskier, but may appeal to some.

http://www.etf.com/sections/features-and-news/top-10-sociall... has some basic details about some popular ones.

If your interested in the opposite there is always the VICEX EFT.

"VICEX, as the ticker implies, holds a basket of stocks specializing in alcoholic beverages, tobacco, gaming and defense/aerospace industries"

Just missing CXW and its 6% dividend to round out the fund.

In this context the "opposite" would be something like an energy or utility ETF (like Vanguard's VDE or VPU), funds that are 100% invested in fossil fuel infrastructure.

I just made an account so I could reply to this - I work on https://fossilfreefunds.org which is a site analyzing mutual fund/ETF portfolios for exposure to fossil fuel stocks. You can see if funds own the 200 largest carbon reserve owners, largest coal-fired public utilities, etc. We also measure carbon emissions metrics for the overall portfolio. And if a fund has a "socially responsible investment mandate" we show that as well.

I don't know of any off the top of my head that only excludes 'not friendly to the environment', but I would look at the other brokers. Schwab and Fidelity both have low cost funds similar to Vanguard.

Also, really low cost might be hard since excluding something like 'not friendly to the environment' is more of an active managed fund. There is this though:

Not a customer but I’ve just learned about https://www.motifinvesting.com

There are other similar platforms like https://www.openinvest.co/. And even if you use a trading platform like Robinhood you can find environmentally-conscious ETFs by searching terms like "fossil free", "green", etc.

Sounds like a business opportunity. I don't think there is a lot of competition in this space yet. You could probably do this with an investment engine that uses a few hundred ETFs to build a portfolio. You'd need decent customer volume in order to make it low-cost, but there are definitely possibilities there.

motifinvesting.com pretty much handles this

SPYX and SPXE are both s&p 500 ETFs that exclude oil. Check the holdings of each, because I know one of them does actually still have some Petro companies.

Fidelity has "green" ETFs.

Thanks I’ll take a look!
