Built for investors who want to make a difference
Your savings can help save the world
Fossil Free Funds is a search platform built to help people find out if their money, in the form of individual investments or an employer-offered retirement plan, is being used to extract and consume fossil fuels.
Owning investments in coal companies, oil/gas producers, and coal-fired utilities isn’t just a moral question. Fossil fuel investments carry real financial risks. When emissions are constrained, fossil fuel companies will have their carbon assets stranded. The implication is that they’re massively overvalued, and markets are realizing that investing in fossil fuels is a risky bet.
Fossil Free Funds empowers investors to know exactly what they own, to see if their savings are invested in dirty energy sources, and to find investment options that support a cleaner, greener future.
Retirement plans

For many of us, the majority of our investments are in 401(k)/403(b) plans offered by our employers. These plans invest entirely mostly through mutual funds and exchange-traded funds (ETFs). But those funds can invest in a wide array of securities, and it’s not always easy for investors to investigate what’s inside the funds they own. Your retirement money may be invested in economically and morally risky fossil fuel companies.

As You Sow

At As You Sow, we’ve been engaging energy companies on climate change issues for many years. When we decided to make sure our own 401k options were fossil free and socially responsible, we thought it would be simple. In fact, it took weeks of digging just to find out what was inside our plan. And what we found shocked us - oil companies, fossil-fired utilities, and other companies avoided by socially responsible investors. We decided it was time for people who aren’t mutual fund experts to know how much of their retirement money was invested in unsustainable fossil fuel operations.

Carbon Underground 200™

Macroclimate® 30

Coal is among the largest sources of global warming pollution in the world. Obtaining it destroys mountains, burning it releases hazardous emissions, and disposing of it results in hazardous toxic waste. Coal is scorching the planet and leaving a legacy of devastation in its wake. We partnered with Macroclimate® to screen mutual funds for the Macroclimate® 30 – an exclusion list of the 30 largest public-company owners of coal-fired power plants in Developed Markets plus China and India.


Over the past years, a growing movement of investors representing trillions of dollars in assets under management have divested some portion of their fossil fuel investments. But where to invest this capital? The corollary of divesting fossil fuels is re-investing in the clean energy future. As an invitation to a larger discussion of how we can invest in this future, As You Sow and Corporate Knights created the Carbon Clean 200 — a list of 200 publicly traded companies that are leading the way with solutions for the transition to clean energy.
