"Sustainability has been a focus of the City of Portland and the Jetport's Capital Improvement Program for the past ten years. I am pleased to have this Bond designated as a Green Bond," said Paul Bradbury, Airport Director. "This is a first for the airport industry, and is in line with our mission to be an environmentally-conscious gateway" he continued.


S&P Global Ratings raised its long-term rating on Portland, Maine's general airport revenue bonds outstanding, issued for Portland International Jetport (PWM), to 'A-' from 'BBB+'. The outlook is stable. "The rating upgrade reflects our expectation that PWM will maintain debt service coverage (DSC) at levels we consider strong, and debt and liabilities capacity at levels we consider very strong, along with no additional debt needs," said S&P Global Ratings credit analyst Scott Shad. 

Moody's Investors Service has affirmed and assigned a Baa1 rating to the Series 2019, also with a stable outlook. The rating agency states that the “... profile reflects the stable economic history of the jetport's service area and the strong airline diversity including multiple low-cost carriers, with the largest carrier accounting for only 30.1% of enplanements. 

S&P Global Ratings separately evaluated and scored the Terminal Project as “Green Bonds". The project, completed in 2012, achieved U.S. Green Building Council (USGBC) Leadership in Energy and Environmental Design (LEED) Gold Certification The 2019 transaction achieves an overall Green Evaluation score of E2/66, which is the second-strongest Green Evaluation score on our scale of E1 (highest) to E4 (lowest).
