Mariners Sustainability

Seattle Mariners SustainabilityThe grass isn't the only thing that's green at Safeco Field. 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.

  • Recycling/Composting

    Annual Recycling RateIn 2014, The Mariners recycled or composted over 85% of all waste generated at Safeco Field. In 2005, the rate was just 12%. Nearly everything used at Safeco Field is recyclable or compostable including food service items (plates, knives, forks, cups, straws, bottles, etc.). Compost and recycling bins have replaced garbage cans on concourses and cleaning crews hand separate plastics and compost able waste after each game. The Mariners concessions partner Centerplate donated over 6.9 tons of food to the Union Gospel Mission and Food Lifeline in 2014.

    During 2014, due to recycling and composting, the Mariners diverted over 2.4 million pounds of waste from the landfill, saving $131,000 in waste disposal costs.

    In 2012 and 2013, Major League Baseball named the Seattle Mariners American League Recycling Champions.

  • Lighting the Way

    Lighting the Way In 2014, the Seattle Mariners became the first Major League Baseball team to illuminate the playing field with LED lights. The 578 GigaTera fixtures use 800 watts of power each. The old technology metal halide lights used 1,000-2,000 watts each. LED lights are 20%-30% brighter, using 60% fewer watts, which will reduce power usage at Safeco Field by 784,000 kWh each season, saving more than $50,000 in energy costs alone. The LED fixtures are also expected to last 30-years, compared with the 2-3 year life span of the old fixtures.

  • Zero Waste Stations

    Zero Waste StationsZero Waste Stations placed strategically throughout the public areas of Safeco Field educate and encourage fans to recycle by placing their waste in the proper containers. There are 16 Zero Waste Stations with containers for recyclable bottles and cans, food waste and compostables, and the only landfill-bound waste containers in the entire ballpark. Because nearly everything used to stage an event at Safeco Field is recyclable or compostable, the landfill waste containers have been replaced by over 400 recycling/compostables containers.

  • Sustainable Saturdays

    Sustainable SaturdaysIn 2011, BASF became the Mariners founding sustainability partner. Through that partnership, the Mariners and BASF have focused attention on various environmental issues through a unique season-spanning awareness program called Sustainable Saturdays. During each Sustainable Saturday, fans learn about how the Mariners and BASF have made Safeco Field one of the greenest ballparks in baseball, and how they can practice recycling and composting at home. Last season, the Mariners recycled over 1,204 tons of food waste, yard waste, plastics, paper and other items that would have gone into landfills.
