Green Bonds

Invest in a sustainable future with a leader in green financing

At Fannie Mae, our mission is clear: to deliver stability and affordability to America’s housing market. We do so primarily by purchasing mortgage loans from lenders and securitizing them into mortgage-backed securities (MBS), which we then guarantee.

Our Green efforts support the Single-Family and Multifamily housing markets by financing homes and communities that meet energy and water saving standards. We offer investors green bonds that build upon our mission where the underlying collateral positively impacts housing infrastructure and the environment.

Offered through our Multifamily Delegated Underwriting and Servicing (DUS®) business, each DUS MBS is generally secured by a single Green mortgage loan collateralized by one property and features guaranty of timely payments, stable cash flows, and liquidity.


  • Guaranty of timely payment of principal and interest.
  • Stable cash flows that are easy to model.
  • Lower spread volatility relative to other products with similar collateral.
  • Superior call and extension protection.

Since issuing our first Multifamily Green Bond in 2012, Fannie Mae has infused over $85 billion into the global green bonds market through nearly 4,000 individual bonds (through year-end 2020). We also established many of the standards and processes adopted industrywide. Our Multifamily Green Bond Framework received a Light Green Second Opinion from CICERO Shades of Green. One of our two multifamily green loan programs, Green Rewards, received a Light-to-Medium Second Opinion from CICERO Shades of Green.

Single-Family Green MBS include either purchase money or refinance mortgage loans backed by newly constructed single-family residential homes receiving approved green building certifications within the last five years. Our Single-Family Green Bond Framework received a Light Green Second Opinion from CICERO Shades of Green.


  • Guaranty of timely payment of principal and interest.
  • Require the ENERGY STAR Certification for New Homes (Residential) designation as a baseline because it is a nationally and globally distinguished standard for energy efficiency.
  • Bolstered by independent third-party verification that underlying properties received eligible certifications.

Since the launch on April 22, 2020 to commemorate the 50th anniversary of Earth Day and through year end 2020, Fannie Mae issued nearly $100 million of Single-Family Green MBS in 2020.
