Mariners Sustainability

The grass isn't the only thing that's green at T-Mobile Park. With a sincere and sustained commitment, the Seattle Mariners are working to significantly reduce our environmental impact.

Since 2006, the Mariners have been leaders in sustainable ballpark operations. Further, we use the power of our position as a community leader to educate and encourage fans, partners, employees and the community at large to make changes both large and small that advance the cause of sustainability.

Alternative Energy

An array of Panasonic HIT® Double solar panels on the skybridge connecting T-Mobile Park to the Mariners parking garage generates 40,000 kilowatt hours of power annually, which is fed into the T-Mobile Park distribution grid.

Solar panels at the Mariners Spring Training headquarters at the Peoria Sports Complex in Peoria, Arizona produce 345 kWh of electricity annually, enough for half of all the team's power needs each year. In addition, the facility received LEED Gold Level certification from the U.S. Green Building Council. LEED, which stands for Leadership in Energy and Environmental Design, is a green building certification program that recognizes best-in-class building strategies and practices. The project was undertaken as part of the City of Peoria Sustainability Action Plan.
