The Single-Family Green Mortgage-Backed Security (MBS) is another important step in Fannie Mae's commitment to leading and innovating in green finance.

As part of our Green Bond Business, Fannie Mae issues Single-Family Green MBS, which 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.

The Single-Family Green Bond Framework received a Light Green Second Opinion from CICERO Shades of Green, a leading global provider of green ratings for bonds. CICERO Second Opinions are independent, research-based evaluations of green bond investment frameworks to determine the environmental robustness of green bonds and offer investors better insight into the environmental quality of these bonds. CICERO recognized that Fannie Mae's single-family green MBS business aligns with the International Capital Markets Association's Green Bond Principles, establishing our green MBS as certifiable green investments.

Eligible Certifications

Fannie Mae selected the ENERGY STAR Certification for New Homes (Residential) designation as a baseline because it is recognized for its:

  • Nationally and globally distinguished standard for energy efficiency
  • Achievement of at least 10% more efficiency than homes built to code and a 20% improvement on average
  • Independent verification by trained and certified Home Energy Raters

Fannie Mae partners with PEG, LLC to verify that all properties underlying the MBS received the certifications.

Future Single-Family Green MBS issuances may include other eligible green building certifications.
