Ethical investors are often told what to avoid investing in, but there is little guidance on the investments to actively seek. This is surprising given that positive ethical investing is much more interesting, more profitable and more likely to effect change in the world. We all know the ‘sin stocks’ to avoid. Tobacco tops the list along with nuclear weapons companies, gambling and, increasingly, fossil fuel companies. Investors have options to avoid these harmful companies and industries. But finding positive ethical investments is harder.
