Climate-friendly investing for all

Don’t invest in fossil fuels
The fossil fuel sector has been the most volatile of the S&P 500 for the past decade. Stranded asset risk further jeopardizes investments as regulations and consumer backlash speed up the transition away from fossil fuels and towards renewable energy.

Votes for the planet
The Fund pools investor voices to vote in favor of climate-related shareholder proposals at the companies it invests in. This pushes some of the biggest companies in the economy to do better on climate, which grows the long-term value of companies by protecting against climate risks and setting them up for success in a changing world.
The top 500 minus fossil fuels
The Sphere 500 index has the top 500 US companies by market capitalization, minus 93 companies. The independent non-profit As You Sow creates the list of fossil fuel and other companies that are excluded.
