We aim to make removing fossil fuel risk easy.
The Sphere 500 Climate Fund is a 7 bp climate-friendly US large cap fund. It does not invest in fossil fuels, and it votes its shares for climate action. Many don't realize that when they invest in a fund, the fund manager votes on their behalf each time a company in the fund has a shareholder vote. Shareholders have the power to hire and fire board members and vote on specific issues submitted by shareholders. Most fund managers vote how boards recommend, which is most often against climate-related proposals. We vote in the long-term best interest of shareholders, which aligns with taking climate action.
A number of family offices and institutions have already exited the fossil fuel industry, often citing worrying economic factors and a need to help protect long-term value as a driving force for decisions, including the Rockefeller Foundation, the New York State Pension Fund, and the Harvard Endowment. The Sphere 500 Climate Fund tracks the Sphere 500 Fossil-Free Index, which tracks the Top 500 US companies by market capitalization and excludes fossil fuel companies to help avoid stranded asset risk.
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.
