Multifamily Green MBS

The Fannie Mae Green MBS is a unique type of Multifamily DUS MBS, which is generally a fixed-income single asset security backed by one loan and one property, providing the investor insight into both the environmental and financial attributes of the asset. In addition to Green MBS, our DUS business allows multiple Green MBS to be packaged together and re-securitized into structured products, like Fannie Megas® (single class pass-through structure) or multiclass Real Estate Mortgage Investment Conduits (REMICs). The REMICs and Megas created from DUS MBS owned by Fannie Mae's Multifamily Capital Markets Desk are called Fannie Mae GeMS™ (Guaranteed Multifamily Structures).

Our Green Bond issuances support properties with Green Building Certifications and the retrofitting of U.S. rental housing stock to become more energy- and water-efficient, resulting in more affordable homes for families and individuals and more cost-effective properties for owners to operate.

Multifamily Green Bond Impact Report

A decade ago, we recognized our nation’s need for more affordable, environmentally sustainable, and resilient housing. In response, we launched our Multifamily Green Financing Business and made it our mission to help address this need.

We developed new multifamily products that created smart, innovative financing solutions to incorporate environmental-savings concepts, including water and energy efficiency, into traditional mortgage lending.

Today, we measure success by the positive "Triple Bottom Line" impact in our communities—financial, social, and environmental benefits to property owners, renters, lenders, and investors. We focus on transparency of these benefits through our at-issuance and ongoing disclosures as well as the publication of our annual Green Bond Impact Report.

These reports demonstrate our commitment to setting bold standards for achievement of the Triple Bottom Line impacts. They detail how retrofitting existing properties and building new green-building-certified properties helps create new jobs and cuts utility costs while reducing greenhouse gas emissions and energy and water use.

Green Financing Criteria & Impact

Environmental Impact per CUSIP: Green MBS and Green REMICs

Fannie Mae Green MBS are a type of Multifamily DUS MBS, which generally are secured by a single multifamily loan collateralize by a single multifamily property. In addition to issuing single-asset backed DUS MBS, our Fannie Mae DUS business provides the opportunity for re-securitization of our DUS MBS into structured products, like Fannie Megas® (single class pass through structure) or multiclass Real Estate Mortgage Investment Conduits (REMICs), which are backed by multiple DUS MBS. The REMICs and Megas created from DUS MBS owned by Fannie Mae's Multifamily Capital Markets Desk are called Fannie Mae GeMS™ (Guaranteed Multifamily Structures).

The detailed requirements of our green lending platform enable us to estimate the projected environmental impact of each Green MBS and Green REMIC CUSIP.
