Problem
Many 401(k) and 403(b) retirement plans include investments in fossil fuels, despite growing investor concern about climate change and the financial risks associated with these assets. Employees often lack climate-friendly investment options within their existing retirement plans, forcing a choice between financial security and environmental responsibility.
Solution
Sphere provides climate-friendly investment options for retirement plans, enabling individuals and organizations to align their investments with their values. The Sphere 500 Climate Fund (SPFFX) tracks the Sphere 500 Fossil-Free Index, which comprises the top 500 U.S. companies by market capitalization, excluding those involved in fossil fuels, deforestation, civilian firearms, military weapons, private prisons, and tobacco. Sphere also offers AtmoSphere, a platform that measures and helps improve a company's 401(k)'s climate impact. By voting shares for climate action and offering low-fee investment options, Sphere empowers investors to promote a sustainable future without sacrificing financial returns.
Target Audience
Sphere's primary customers include HR managers, benefits managers, CFOs, and 401(k) advisors seeking to offer climate-friendly investment options to employees, as well as individuals looking to invest in a fossil-fuel-free fund.
