In September 2017, the MBTA issued the first tax-exempt sustainability bond in the United States. The $99 million issue financed more than 100 projects within the Authority’s capital improvement plan with clear environmental and social benefits. Since that first offering, the MBTA has issued an additional $217 million in sustainability bond anticipation notes and $45.6 million in sustainability bonds. 

The MBTA’s Sustainability Bond was recognized as The Bond Buyer’s 2017 Northeast Regional Deal of the Year, and was a finalist for the National Deal of the Year.
