A number of investors are not solely interested in making money, but also in making a difference with their investments. Although there is a smaller choice of ethical or environmental investments, if you look in the right places you can find funds that are not simply good because of their returns. Increasing government regulation and interest in investments with this focus could help the returns of funds in these areas going ahead.
