Green Century is the first family of fossil fuel free mutual funds in the U.S. that are environmentally friendly and diversified.

We offer shareholder advocacy internships to talented and motivated individuals each semester and over the summer.

Green Century uses a unique three-pronged approach:

Green Century:

  2. Leads and effective shareholder advocacy program: Our team of shareholder advocates directly presses several nearly 100 companies every year to improve their corporate sustainability practices.
  3. Supports environmental and public health nonprofit organizations: Green Century is the only mutual fund company in the U.S. 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.
