Join the Green Century° Team!

Green Century Capital Management (Green Century) is the investment advisor of the Green Century Funds, one of the first families of responsible and diversified fossil fuel free mutual funds in the U.S.

For over 30 years, Green Century has been the standard bearer of environmentally responsible investing. Green Century uses a three-pronged approach to deliver impact while seeking competitive returns.

Green Century:

  • Invests in companies aligned with environmental values.  Instead of investing in environmentally dangerous industries such as coal, oil, gas and tobacco, Green Century Funds avoids these companies so that clients can match their ethics to their investments.
  • Leads an award-winning shareholder advocacy program.  Our Green Century shareholder advocacy team directly presses global companies to improve their corporate sustainability practices.
  • Supports environmental and public health nonprofit organizations.  Green Century is wholly owned by environmental and public health nonprofit organizations, and 100% of the profits we earn managing the Green Century Funds can be used to support their critical work.
