Keep the same business, just throw the words " socially responsible", "ethical", "for development", "against climate change" all over the website. It doesn't mean anything anyway... If you have an HFT firm, it's just a socially, ethically and economically equitable proprietary trading firm. Trade 2 lots of ethanol in the year and you are fighting climate change. Give 0.2% of your profits and it is a charity. Trade 2 lots on the mexican exchange and you are acting for development. If you look at politicians/regulators decisions, it just has to sound good today, nobody cares what you are really doing... Whatever
By the way, if you are promoting ethanol, you are not fighting climate change at all, but I am sure 80% of people wouldn't even notice it. It is just a thing that sounds good...LOL
