For more than ten years Fannie Mae has been a leader in Green Financing, supporting our mission to provide sustainable affordable rental housing throughout the United States.

Thanks to your partnership, we’ve issued nearly $88 billion in Multifamily Green MBS since 2012, and we remain the largest issuer of green bonds in the world. We recently released our 2020 Green Bond Impact Report – the latest look at the substantial progress, innovation, and vision that you’ve helped make possible.
