Arizona Diamondbacks 2025 Season Sustainability Highlights:

Since installing a synthetic grass playing surface, the Diamondbacks have saved over 100 million gallons of water, averaging 15 million gallons annually.
Increased the ballpark’s waste diversion rate by 18% from 2024 to 2025.
Collected and washed 38,701 reusable cups in partnership with Bold Reuse, diverting nearly a ton of waste from landfills in the first year of the program alone.
Consumed 90% less natural gas than the average MLB ballpark throughout the 2025 season, made possible by Chase Field’s efficient district cooling-loop system. · Energy efficiency upgrades at Chase Field and the transition to 446 LED sports lights on the field have led to 50% energy savings. As of spring 2026, 75% of the buildings have been converted to LED lighting, reducing overall energy use while maintaining a top-tier fan experience.

How We Go Green

Energy

100,000 kWh of electricity generated annually by the APS Solar Pavilion, enough to power the ballpark lights for 11 D-backs home games each year. 50+ XLERATOR® hand dryers replaced paper towel dispensers in concourse restrooms, eliminating the use of more than 1,000 miles of paper towels from the annual waste stream since their installation in 2017. 40% reduction in annual energy consumption resulting from parking garage lighting upgrades.

Materials and Resources

First MLB ballpark to introduce a reusable cup program through a partnership with Bold Reuse. D-backs reusable cups are available in the Bar-S All-You-Can-Eat Sections (221–223) and Estrella Jalisco Cantina. 98% of D-backs Bold Reuse cups were successfully washed and returned for reuse. 200+ Max-R dual-stream recycling bins installed throughout the concourses in partnership with Waste Management. 1,300 recycled milk jugs are used to manufacture each ballpark recycling container. 16 recycled plastic bottles are repurposed to create each RPET polo shirt worn by the majority of Concessions staff.

Concessions

24+ tons of prepared food donated through the Waste Not Program since 2023.
A wide variety of compostable and biodegradable service ware is available throughout the ballpark.
Souvenir cups are available for purchase at most concession stands, encouraging fans to take them home for continued reuse.
All D-backs Advantage Members receive a complimentary reusable cup to use for refills at every game and take home for future use.
Fans are welcome to bring an empty reusable water bottle and refill it at complimentary water stations located throughout the ballpark.

Water Efficiency

Updated pressure-washing procedures have resulted in an additional 400,000 gallons of water savings per month. Low-flow aerators installed on all ballpark faucets have reduced water usage by 30–50%. High-efficiency restroom fixtures, including dual-flush toilets and low-flow urinals, use 20% less water than standard fixtures.
