Outside of funds, I like to buy into companies with tech I believe in, over trying to get a profit(with full hopes to make money, don't get me wrong, it's just not the primary driver). Not going to say who, but I like certain green energy companies because they actually have solutions in development or production. Amazing though as a moral premise, it has also been profitable as well in nearly each case, just maybe not as profitable as others.
IMO, you put your money where your mouth is, if you believe in solutions, then fund them and not just support them in spirit and make for internet debates to show your loyalty. In the US and a few other markets, it's fairly easy to do this. Ugh, even kickstarter/crowdfunding, although those are IMO some of the worst and least effective examples of supporting ideas.
