If you’ve ever perused the Forbes Fortune 500 (a list of the top 500 United States public corporations as measured by their gross revenue), you may have noticed that the list includes mammoth companies, most of which do not have great environmental track records. And because of their healthy stock prices and market domination, investing in these companies is often compulsory when participating in employer-based investment plans.

It is possible to invest in Green corporations however, all it takes is a little determination and research to find funds you can feel good about supporting. I’ve compiled a list of Green and eco-friendly investment options to consider when deciding where you want to invest your money:

1. The Sierra Club offers mutual funds that have been, “designed to invest only in companies that meet its social and environmental guidelines.” The Sierra Club Stock and fund meets the Sierra Club’s environmental and social guidelines, but according to the Motley Fool investment gurus, financially, it doesn’t perform all that well.

2. Portfolio 21 Investments is an investment company that specializes in investing in companies who “design environmentally friendly products, use renewable energy sources, and develop efficient production methods.” Based in Portland, Oregon, Portfolio 21 has a global outlook to its investing, and holds more than 65% of its stocks in international companies.

3. In addition to mutual funds, you can also invest responsibly in individual corporations, such as Whole Foods Market and Starbucks – both companies have a history of forward-thinking environmental policies, even as they’ve grown and come to dominate the US landscape.

Make sure you consult your financial adviser before investing in any of the products mentioned above. Additionally, the Motely Fool has a Green Investing series on their website from which much of this information was compiled and is a great starting point for research into Green Investing.
