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.

Baltimore Orioles

As part of the Baltimore Orioles Orange and Black Gives Back volunteer program, Orioles employees will participate in an Earth Day volunteer project with Parity Homes in the Harlem Park neighborhood of West Baltimore, serving the community of our recently announced Adopt-A-School program at Harlem Park Elementary Middle School. Volunteers will help with building benches, laying pavers, installing plants, picking up debris in the neighborhood and sorting books, among other tasks. Parity Homes is an equitable development company proudly headquartered in West Baltimore that acquires and rehabilitates abandoned properties by the block to create affordable home ownership opportunities.

Chicago Cubs

On Earth Day, Tuesday, April 22, the Chicago Cubs will take on the Los Angeles Dodgers at Wrigley Field and will hand out reusable Earth Day tote bags presented by Hefty to the first 10,000 fans to enter the ballpark. The Cubs will also partner with the American Conservation Coalition and Hefty to activate a “Green Team” throughout the ballpark to divert additional mixed recycling from landfills. This past weekend, the Cubs hosted a Neighborhood Grounds Crew clean-up event with Hefty where more than 100 Hefty employees and community volunteers joined forces to clean up a local park.

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 on-site 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.

Cincinnati Reds

The Reds are continuing their recycling program in 2023, which includes on-site cardboard baling, comingled recycling and e-waste. The Reds have worked with the ballpark’s energy supplier to provide Great American Ball Park with 25% renewable energy, and all ballpark lighting is now LED, including field lights. Concessionaire Delaware North is partnering with the “Last Mile Food Rescue” organization to deliver unused ballpark food to local nonprofit agencies. Delaware North team members have been collecting bottle caps for Earth Connection’s “Bottle Caps to Benches” project.

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 their responsibility to protect and promote the well-being of the local community. Accordingly, the Yankees remain committed to inspiring their 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 operations, including greenhouse gas emissions, energy use, water use and waste generation. The Yankees are committed to compliance with all applicable environmental regulations and support the development of innovative economic and socially beneficial solutions to help reduce or offset the direct and indirect impacts engendered.

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 their ability in an effort to identify opportunities for improvement in reducing eco-impacts.

Their focus is on implementing emission reduction as soon as it is feasible, and the 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 their unavoidable team aviation emissions, the Yankees 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. The Yankees' 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.

Athletics

In an early celebration of Earth Day, the A's teamed up with Goodwill of San Francisco Bay to host an electronic waste collection drive at the Coliseum on April 13. Fans were encouraged to donate old or unused electronics to help protect our local environment. For every item donated, fans received two ticket vouchers to a 2024 A’s regular season home game.

Additionally, fans who purchase a special event ticket for the A's Earth Day game versus the Nationals at athletics.com/earthday will receive a discount on their ticket purchase, and a portion of the proceeds will benefit Goodwill of San Francisco Bay's mission to provide job training and career services.

Pittsburgh Pirates

To celebrate Earth Month, the Pittsburgh Pirates distributed reusable water bottles to all front-office employees. New waste bins have been introduced throughout the ballpark, featuring clear messaging to help guests dispose of their waste in the correct stream. The old-style waste bins were donated to local organizations, Westmoreland Cleanways and Fayette County, where they will be repurposed and used in local parks.

In partnership with 412 Food Rescue, a food donation pickup will occur on Earth Day, following the previous homestand. We have launched a signage and education campaign to raise awareness about sustainability among our fans. Through signage and in-game messaging, we are encouraging sustainable practices and highlighting the partnerships of our sustainability program. Water bottle filling stations have been installed for guests to promote sustainability and reduce plastic waste.

San Diego Padres

• Social media posts
• Resharing press releases about awards from MLB to Padres' 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.

San Francisco Giants

In celebration of Earth Day on April 22, the San Francisco Giants are proud to highlight their ongoing sustainability efforts and community partnerships, including a collaboration with Forever Giant Hunter Pence in support of his nonprofit, Healthy Planet Project (HPP).

HPP works to reduce and prevent pollution while creating a healthier environment across the Bay Area. Its programs focus on city cleanups, climate change mitigation and raising awareness for local environmental initiatives, with priorities including building a more resilient Bay, planting trees, supporting youth education, and enhancing parks and public spaces.

Sustainability efforts at Oracle Park remain central to the organization’s environmental commitment. In partnership with Vytal Global, the Oracle Park Replay Program -- new this season and the first of its kind at a stadium-wide scale -- serves beverages in reusable cups that are collected, sanitized and reused throughout the ballpark. Additionally, Eco-Products, the Club’s Zero Waste partner, provides compostable foodservice packaging made from renewable and recycled materials.

As part of Climate Week (April 18-26), the Giants have also joined forces with California Volunteers and the State of California to promote the Climate Action Counts campaign, which aims to inspire one million Californians to take everyday climate actions for collective impact.

Fans can learn more about the Giants’ sustainability initiatives and ongoing environmental efforts at Oracle Park.

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 2025 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.
