Earth Day

Arizona Diamondbacks

As part of the Arizona Diamondbacks’ Earth Day celebration on Wednesday, April 22, the organization is highlighting the impactful sustainability efforts taking place throughout Chase Field, including 50% energy savings following the transition to 446 LED sports lights on the field and 75% of the ballpark now upgraded to LED lighting throughout the building. Since installing synthetic grass in 2018, the organization has saved 15 million gallons of water annually, while updated pressure washing procedures conserve an additional 400,000 gallons per month. The Club has also diverted more than 2,700 pounds of waste from landfills through its reusable cup program in partnership with Bold Reuse, and recently launched a new aluminum can recycling initiative during the first homestand to capture recyclable materials from grab-and-go locations, with plans to expand stadium-wide. Building on the success of the Club’s reusable cup program -- originally launched in the Bar-S All-You-Can-Eat Seats as the first initiative of its kind at a Major League Baseball facility -- the D-backs are now expanding the program to all Chase Field employee break rooms in partnership with Bold Reuse, further reinforcing the organization’s commitment to reducing single-use waste and empowering staff to lead by example in sustainability efforts.

Fans can also connect with local nonprofit partners Growing to Give and the Phoenix Food Forest Initiative, who will table on the concourse to distribute seed packets and educational resources promoting food security and sustainable practices. Throughout the April 22 game, the D-backs will feature Earth Day-themed entertainment, including the fan-favorite “Recycle Frenzy” during the sixth inning in collaboration with Budweiser and volunteers from Keep Phoenix Beautiful, along with Kids Club Earth Day coloring activities and additional educational and promotional materials available throughout the ballpark.

Atlanta Braves

April 21: Pitch In for the Planet presented by Coors Light

• Time: 9 a.m.-12 p.m. ET
• Location: Food Well Farm (formerly Leila Valley Community Farm), 2370 Locust Ln. SE, Atlanta, GA 30315
• Details: In celebration of Earth Day, Braves and Molson Coors employees, along with Braves A-List Members, will team up to serve and beautify Food Well Farm, also the site of a 2025 MLB All-Star Legacy Project. (Video from 2025 All-Star Week can be found here).
  • Every year, Atlanta Braves front-office staff works alongside Molson Coors employees to serve neighborhood orchards, farms, gardens and green spaces.

Maggie the Magnolia: On Earth Day 2021, the Atlanta Braves added a piece of Atlanta baseball history to Truist Park with the planting of a seedling from a 113-year-old Magnolia tree that grew in the outfield of Ponce de Leon/Spiller Park. Home to Minor League’s Atlanta Crackers and Negro American League’s Atlanta Black Crackers, when the ballpark opened in 1907, the magnolia was approved to remain inside the ballfield’s footprint. The seedling, which has been nicknamed Maggie, stands at the corner of Circle 75 Parkway and Windy Ridge Parkway SE, where a marker was installed in partnership with the Atlanta Botanical Garden to share information on the tree and the history of its origins. The Braves will celebrate Maggie’s fifth birthday on Earth Day 2026.

The Atlanta Braves organization proudly supports and encourages sustainability practices across all platforms, including eco-conscious partnerships, community outreach programs, fan-facing opportunities and back-of-house operations.

This commitment was in the forefront in the planning and design of Truist Park and resulted in a LEED Certified Silver -- New Construction designation. With a 30,000-gallon in-ground water retention tank used for field maintenance, LED lighting throughout the building, low-flow water fixtures and centralized utility control systems, Truist Park and the Atlanta Braves serve as an example of best practices throughout Major League Baseball.

Atlanta Braves facility operations coordinate multiple recycling efforts as part of their day-to-day operations. To help reduce waste, Truist Park bar locations and club spaces feature aluminum cups from Ball Corporation.

The Atlanta Braves partner with Second Helpings Atlanta to recover excess food from Truist Park at the end of each homestand. Tens of thousands of pounds of food every year are rescued and served to communities experiencing food insecurity.

The Braves Green Team -- a partnership between the Braves, WestRock, Coca-Cola and Ball Corporation -- activates at Truist Park during select games each season. Volunteers in green T-shirts walk around the stadium and down the aisles in between innings to collect recyclables from fans and encourage environmental responsibility.

Boston Red Sox

The Red Sox will recognize Earth Day during pregame ceremonies highlighting the club’s ongoing commitment to sustainability at Fenway Park on Wednesday, April 22. As a founding member of G.O.A.L. (Green Operations and Advanced Leadership), the Red Sox helped establish a new standard for environmental responsibility in sports. Through this initiative, Fenway Park was recently recognized with gold, silver and bronze distinctions across 11 sustainability categories.

The Club and its concessionaire, Aramark, will also recognize their partnership with Rescuing Leftover Cuisine, which helps redirect surplus food from Fenway Park events to local nonprofit organizations. Since the Fenway Park food donation program’s launch in 2024, the initiative has prevented nearly 18,000 pounds of carbon emissions while supporting local food access through the donation of thousands of pounds of surplus food.

Additionally, any ticketed fan who bikes to Fenway Park on April 22 will receive a complimentary hot dog or pretzel and water, courtesy of Aramark, by presenting a bike valet voucher or Bluebikes receipt at Gate D Fan Services.

Members of the Club’s front office sustainability team will be joined on the field by representatives from local government and industry partners.

Chicago White Sox

The Chicago White Sox have a longstanding commitment to sustainability at Rate Field, embedding environmentally responsible practices across all ballpark operations. The Club is the recipient of both MLB’s Power Pitch Award, honoring organizations that demonstrate exemplary efforts in preserving energy and power, and Green Sports Alliance’s Play-to-Zero Energy Efficiency Champion Award, for which ComEd will run a case study on the ballpark’s 24% reduction in energy usage.

Over the past year, the organization has made measurable progress to lowering its environmental footprint. Ballpark electricity consumption is down 17.7% year over year, while water usage has decreased by 7.32%, supported in part by the installation of nearly 200 low-flow faucets throughout the ballpark. The Club also achieved a 30% waste diversion rate through expanded recycling and composting initiatives. Food waste mitigation remains a central focus. The organization has composted 78.8 tons of material and recycled more than 40 tons of cooking oil to prevent 21,600+ kg of CO₂ emissions. Concessions partners Delaware North and Levy have further supported these efforts by transitioning to aluminum cups and plant-based service ware.

Additional initiatives include the recycling of 572 pounds of textiles since introducing the front-office staff offering in late 2025, the launch of a scrap metal diversion program that has already diverted approximately 12,000 pounds, and the reuse of nearly 1,000 wooden pallets. Twenty public-facing water bottle refill stations encourage fans to reduce single-use plastics, while an onsite garden supplies fresh herbs and vegetables for premium kitchens. Extending beyond the ballpark, the White Sox Charities-supported Sox Give team will volunteer at Southside Blooms Englewood Farm on April 21 to help with trash and debris pickup, weeding and compost building.

In partnership with OC Waste & Recycling, the program recognizes students, educators, classrooms and clubs demonstrating leadership in sustainability.

The Green Hero winner will receive tickets to a regular-season Angels home game for their classroom or club and be individually recognized on the field by the Angels Baseball Foundation and OC Waste & Recycling.

Miami Marlins

• WM will be tabling on the concourse during the game to share how they've played a pivotal role in our sustainability journey and to educate fans on proper recycling habits.
• Fertile Earth Worm Farm will also host a concourse activation, providing educational materials and showcasing plants grown in compost created from ballpark food waste.
• A feature article highlighting sustainability initiatives will be published on the Marlins’ website and LinkedIn.
• Social media graphics will highlight 2025 diversion metrics and potentially include World Baseball Classic data.

The Miami Marlins continue to implement a comprehensive environmental program at loanDepot park focused on waste diversion, recycling and resource conservation. These efforts are supported through ongoing collaboration with Major League Baseball and WM’s Sustainability Advisory Services, with a focus on developing scalable solutions that can be implemented across ballparks league-wide.

Throughout loanDepot park, dual waste and recycling receptacles with clear signage are available to fans, supporting proper material separation on the concourse and enhancing recycling participation during games and events. Following each game, all collected recycling materials are transported to a centralized sorting area, where 100% of recycling bags are manually sorted to reduce contamination and maximize material recovery, ensuring recyclable items are properly diverted from landfills.

More than 80 tons of material, including cardboard, aluminum and mixed recyclables, were successfully recovered through these efforts last year.

In addition to recycling, the Marlins have implemented a food recovery program in partnership with Food Rescue South Florida, donating nearly three tons of excess food during the 2025 season to support local communities. Food waste that cannot be donated is composted through a local partner, with more than 28 tons of organic material diverted and repurposed into nutrient-rich soil.

Sustainability efforts extend into food and beverage operations, where aluminum packaging has been introduced to reduce plastic usage, and used cooking oil is recycled into biodiesel, contributing to reduced greenhouse gas emissions.

Milwaukee Brewers

On Saturday, April 25, the Brewers Beyond the Diamond employee volunteer program is teaming up with Milwaukee Riverkeepers and WM employees to clean up a stretch of the Menomonee River along the Hank Aaron State Trail, adjacent to American Family Field. Milwaukee Brewers have adopted this stretch of the Menomonee River Valley for the past three seasons and have consistently committed volunteer efforts toward maintaining and improving the area.

New York Yankees

The New York Yankees organization recognizes our responsibility to protect and promote the well-being of our community. Accordingly, the Yankees remain committed to inspiring our partners, players, fans and employees to create a sustainable environmental legacy. In pursuit of these goals, the Yankees seek to measure and minimize identifiable environmental impacts related to our operations, including greenhouse gas emissions, energy use, water use and waste generation. The Yankees are committed to compliance with all applicable environmental regulations, and we support the development of innovative economic and socially beneficial solutions to help reduce or offset the direct and indirect impacts we engender.

The Yankees have been monitoring key environmental performance indicators related to Stadium operations and procurement since 2009, when the new Stadium opened. Energy use, greenhouse gas emissions, water use, waste management, recycling, composting, transportation and the procurement of goods and services, among other impact categories, are regularly evaluated to the best of our ability in an effort to identify opportunities for improvement in reducing eco-impacts.

Our focus is on implementing emission reduction as soon as it is feasible, and our 2024 installation of two higher-efficiency chillers (to replace four chillers that were installed when the Stadium opened) is a notable example of that effort. For our unavoidable team aviation emissions, we have invested in a limited amount of high-quality, third party-verified GHG offsets that have been carefully chosen to advance the United Nations’ Sustainable Development Goals.

Additionally, the Yankees are committed to promoting a circular economy based on recycling, composting, food donations, anaerobic processing of food waste and other organic materials and the recovery and use of waste oil. Concession stands provide fans compostable food-service packaging (trays, boxes, plates and cups) and cutlery, rather than non-compostable petroleum-based plastics, and priority is given to composting food waste to avoid combustors and landfilling. Cardboard, glass, metal, plastics and paper are recycled as well. Our commitment to reduce food waste also includes donations of wrapped, unused food to organizations such as Rock and Wrap It Up, which directly combats hunger in the metropolitan area.

The Yankees formalized their decades-long commitment to sustainability in 2019 by becoming the first team in professional sports to create an Environmental Science Advisor position, appointing recognized industry leader Dr. Allen Hershkowitz to the new role. A few months later, the Yankees became the first major North American sports team to sign on to the U.N. Sports for Climate Action Framework. Read more about the Yankees’ sustainability efforts.

Philadelphia Phillies

In an effort to bring awareness to sustainability practices, the Phillies and Asplundh recently hosted Pitch in for the Planet at Citizens Bank Park on Tuesday, April 14, before that night’s game against the Chicago Cubs. Fans who attended this Theme Night event received a voucher for an exclusive eco-conscious cooling towel.

The organization will also host its annual front office Earth Day volunteer opportunity on Wednesday, April 22, at FDR Park, located just down the street from Citizens Bank Park. Efforts this year will be in partnership with the Fairmount Park Conservancy with projects including tree care, weeding, mulching, watering trees and shrubs and trash cleanup as needed.

Throughout the season, the Phillies will continue to partner with Aramark and ABM on their Red Goes Green sustainability program, which launched in 2008, focused on reducing the environmental impact of Citizens Bank Park. The initiative features extensive recycling of plastics, metals and materials, composting of food waste, and LED lighting.

The Red Goes Green program also features the Home Runs for Trees campaign. For each home run hit by a Phillies player during the season, a tree is planted as part of Home Runs for Trees presented by Asplundh and in partnership with the Pennsylvania Horticultural Society. More than 2,400 trees have been planted in the Delaware Valley since the inception of the program. In addition, through the program, hundreds of trees have been donated to local schools.

San Diego Padres

• Social media posts
• Resharing press releases about awards from MLB to our press lists
• Front-office lunch and learn/tour of waste operations and energy efficiency
• Potential touch-a-truck activation for fans in partnership with Republic Services
• Goal to get compostables in front-office coffee shop by Earth Day

While the Padres are playing on the road this Earth Day, the organization has plans to celebrate with a special tour of Petco Park’s sustainability offerings for front-office employees. The tour will showcase the building management system, chiller plant, backup energy storage system and the trash-sorting area for waste diversion. Other tour highlights include e-waste and battery recycling, on-site solar and LED technologies and other technological changes that aid the ballpark's electrification in an effort to meet California’s decarbonization and short-lived climate pollutant targets. In addition to the front-office tour, the Padres and their partner, San Diego Community Power, will collaborate on a social media post that will inform fans about the ballpark’s energy efficiency.

The Padres' facilities team has also worked diligently to convert all foodware products in the Padres’ multipurpose room to compostable items. Compostable plates, bowls and cutlery will be available for front-office staff on or shortly after Earth Day. This change will support Petco Park’s waste diversion efforts en route to a more sustainable San Diego.

St. Louis Cardinals

The St. Louis Cardinals, in partnership with the team’s landscaping services provider, Focal Pointe, supported a community-wide environmental restoration initiative to replant 350 trees that were lost in O’Fallon Park during the May 16, 2025, tornado that devastated the North St. Louis community. As part of a tree-planting effort through Focal Pointe’s Broken Bat Program, which provides a tree for every bat a Cardinals pitcher breaks of an opposing batter, members of the Cardinals front office and Focal Pointe planted 38 trees Monday, March 30, for the 38 bats broken by Cardinals pitchers during the season.

The Cardinals will also participate in the St. Louis Earth Day festival, April 25-26, operating a booth on-site that promotes the organization’s Green Team initiative that utilizes volunteer members to help collect recyclables from fans throughout each game at Busch Stadium.

Tampa Bay Rays

The Tampa Bay Rays are celebrating Earth Day at home April 22 against the Cincinnati Reds. Emmanuel Roux from 15th St. Farm will throw out the ceremonial first pitch.

15th St. Farm is a nonprofit urban organic farm in St. Petersburg, Fla., that facilitates learning and community building around healthy food from soil to fork. Tampa Bay Watch will have a table featured prominently at Tropicana Field for fans to learn about their mission and educational programs. Tampa Bay Watch is dedicated to fostering a healthy Tampa Bay watershed through community-driven restoration projects, education programs and outreach initiatives.

Washington Nationals

Nationals Park was a pioneer in green design upon its construction and is considered one of the most environmentally friendly ballparks in the country today. Built on brownfield and constructed using 95% recycled steel and 35% regionally sourced construction materials, Nationals Park became the first major sports facility in the U.S. to earn the LEED-certified Silver designation by the U.S. Green Building Council. The Washington Nationals’ commitment to green initiatives has been recognized by Major League Baseball in recent years; the Nationals have won multiple sustainability awards, including the 2026 H2O Home Run Award, which recognizes the Club that has demonstrated exceptional dedication and achievement in reducing its water usage from the previous year. Additionally, the Nationals were named NL East Green Glove winners for three consecutive years (2020-22) and National League winner in 2021.

Nationals Park’s design elements feature energy-efficient LED lighting for the field and stadium parking garages, rooftop canopies that contain 4,080 solar panels installed above the two stadium garages that now supply roughly 10% of the ballpark’s electricity and a comprehensive water conservation program that saves an estimated 3.6 million gallons annually and reduces consumption by 30%. Additionally, the ballpark’s Giving garden -- a 6,300-square-foot rooftop garden located by Section 105 -- has helped to reduce heat gain while producing fresh fruits and vegetables for Washington, D.C.’s Wards 7 and 8. A photo panel of the Giving Garden will be featured in the 2026 Smithsonian Gardens campus-wide exhibition series Growing Tomorrow at the National Museum of American History beginning in May. Ballpark-wide composting and recycling programs and bottle-filling water stations further support waste-reduction efforts, while the Nationals Park’s stormwater filtration system helps protect the nearby Anacostia River. For fans, Nationals Park is also conveniently accessible to public transportation via Metro and buses, and signage throughout the concourses helps to educate fans on the Nationals’ sustainability initiatives.

During their game on Wednesday, April 22, Earth Day, the Nationals and Bayer will host Agriculture Night, with several fan activations on the main concourse, including:

• The Bayer Experience Box, where fans can learn about the importance of farming and agriculture, plus receive T-shirts, sunscreen and hand sanitizer while supplies last.
• Fans can write gratitude letters to farmers at mailbox stations located in several areas around the concourse, including Center Field Plaza.
