Environmental stewardship

We are committed to improving environmental sustainability in the homes we finance, the communities we serve, and the places we work. Through our Green Bond business, we offer a transparent and high-quality investment opportunity to global investors seeking to accelerate the transition to a low-carbon economy. We seek to better understand and mitigate climate change-related risks to housing while reducing the environmental footprint of our operations.

Green bonds 

We are recognized as the world’s largest issuer of green bonds – fixed income products that enable positive environmental, social, and economic outcomes. Our Green Bonds are Mortgage-Backed Securities (MBS) collateralized by loans that finance energy- and water-efficient homes and properties. In 2019, we celebrated 10 years of Multifamily Green Financing, and in 2020, we expanded our offerings to include Single-Family Green Bonds. Through December 2020, we have issued nearly $88 billion in Multifamily Green MBS and approximately $11 billion in Green re-securitizations, and $94 million in Single-Family Green MBS.

Our widely recognized green bond business offers fixed income investors with quality, liquid, green investment products that feature long-term income and steady returns. We currently offer three types of green bonds to investors with the transparency of CUSIP level impact reporting. Fannie Mae’s Single-Family and Multifamily Green MBS both received a Light Green Second Opinion from CICERO Shades of Green. This Second Opinion is important because it is an independent, research-based evaluation that determines the environmental value of green bonds and offers investors insight into the environmental quality of green bonds. CICERO recognized that Fannie Mae's Green Bonds align with the International Capital Markets Association's Green Bond Principles.

Our Recognition

ESG Environmental Climate Risk

Climate risk 

Recent years have seen frequent and severe natural disasters in the U.S., including hurricanes, wildfires, and floods. The increased frequency, intensity, and unpredictability of major natural disasters pose risks for all stakeholders in the housing system, including homeowners, renters, lenders, investors, and insurers. Our Climate Impact team was established to assess that risk on an ongoing basis and is identifying strategies to mitigate the resulting impacts.

Climate resilience 

Beyond managing the credit risks inherent in natural disasters, helping families and communities recover and become more resilient is an important part of our work. Fannie Mae’s Disaster Response Network™ offers renters and eligible single-family borrowers free financial counseling from HUD-approved housing advisors, including help in developing a recovery assessment and action plan, filing claims, working with mortgage servicers, and identifying and navigating sources of federal, state, and local assistance. Our Disaster Rebuild Deployment program provides opportunities for our employees to participate in clean-up activities as well as home repairs and rebuild efforts with the goal of reducing the time it takes for a family to return to a safe and stable home after a disaster.

ESG Environmental Sustainable Operations

Sustainable operations 

We are committed to managing the environmental impacts of our operations. Our focus on environmental sustainability is reflected in our Green Building-certified offices. Though we manage a book of business that exceeds $3.7 trillion, our physical footprint is smaller than may be expected. The majority of our approximately 7,700 employees are based out of just four office buildings.

In 2018, we relocated our Washington, D.C., headquarters to a LEED Gold building. Our Dallas offices are now in a single LEED Silver building in Plano, Texas. In 2020, our D.C. office derived 45% of its energy from renewable sources, and our Reston Crescent, Virginia, location derived 100% of its energy from renewable sources.
