At Marriott International, caring for the places where we live, work, and travel isn’t just something we focus on once a year; it remains central to how we do business and is guided by our sustainability and social impact platform, Serve 360.
This Earth Day, Marriott is proud to share how our associates, hotels, and guests are helping bring our Serve 360 efforts to life, including through our goal to conduct 35,000 activities that protect, restore, or enhance nature in the communities where we operate by 2030.
From reforestation and marine conservation to responsible operations and community partnerships, we’re proud of the progress we made in 2025:
“The health of our business is deeply connected to the health of our planet. When we protect the environment and invest in our communities, we’re dedicated to helping destinations remain vibrant places to live, work, and visit for generations to come.”
– Anthony Capuano, President and CEO, Marriott International
Marriott properties and associates around the world have been dedicating their time and resources to helping nature thrive on land and at sea. Learn more about efforts happening across our Marriott Bonvoy portfolio.
On Land: Reforesting Critical Ecosystems – One Tree at a Time
Healthy forests do more than look beautiful, they filter water, cool waterways, stabilize soil, and create shelter for wildlife. In 2025, Marriott helped plant more than 32,500 trees in critical ecosystems across the U.S. Gulf Coast through our engagement with the Arbor Day Foundation. The initiative’s aim is to restore a diverse blend of bottomland hardwood and upland pine forests across Alabama, Florida, Georgia, and Mississippi as part of the Gulf Coast Reforestation project. These reforestation efforts support local recovery from hurricanes, coastal flooding, and land-use changes – and help improve regional watershed health by reducing pollution and erosion that can flow into streams and eventually the ocean. As canopy returns along waterways, it can enhance habitat for aquatic species such as mussels, crawfish, oysters, gulf sturgeon, and manatees, while also supporting land-dwelling wildlife like gopher tortoises, eastern indigo snakes, and the endangered red-cockaded woodpecker.
Through Good Travel by Marriott Bonvoy® and collaboration with China Green Foundation’s Million Forest Project, guests helped reach a milestone of 10,000 shrubs donated to support efforts to combat desertification in Gansu Province, China.
Closer to home in Maryland, we continued to support the Chesapeake Bay Foundation’s efforts to plant trees that protect waterways with approximately 4,000 trees planted across the state in 2025, and another 10,000 seedlings potted and nurtured in nurseries for future reforestation.
At Sea: Protecting Coastlines and Marine Life
Coastal ecosystems are powerful and fragile. In Costa Rica, volunteers from W Costa Rica – Reserva Conchal and The Westin Reserva Conchal, an All-Inclusive Golf Resort & Spa, supported Back Home, a program dedicated to returning seashells to the sea. Using science, innovation, and collaboration, an artificial intelligence application helps identify whether shells confiscated at the airport belong to the Pacific Ocean or Caribbean Sea so they can be registered and reintegrated into their original habitat. Returning shells helps secure micro-habitats for animals and microorganisms and can help minimize the impacts of coastal erosion.
Across the Caribbean and Latin America region, properties continued year-round programs dedicated to sea turtle conservation. In 2025, these efforts helped support the release of more than 63,000 turtles into their natural habitats.
Marriott is also working with World Wildlife Fund (WWF) to support healthier oceans through the Peru Mahi Mahi Longline Fishery Improvement Project – an effort aimed at strengthening management practices and safeguarding the broader marine ecosystem.
Our Power Is People: Turning Commitment into Action
None of this work happens without people. In 2025, associates, hotels, and Marriott Business Councils reported participating in 7,500 biodiversity-related activities – from clean-ups and ocean conservation to reforestation – reflecting the everyday actions aimed at helping to protect the places where we live, work, and travel. In support of the 2025 World Environment Day, 8,300+ volunteers across 230 hotels supported community and conservation efforts –planting nearly 95,000 trees and more than 11,000 mangroves, alongside activities such as beach clean-ups and coral plantings.
Guests and Marriott Bonvoy members play an important role too. Through the Marriott Bonvoy member Annual Choice Benefit, members helped raise more than $280,000 for World Wildlife Fund to support global conservation efforts. And across our portfolio, stewardship of the natural world continues to be recognized: 93% of U.S. & CALA golf properties and 100% of U.K. golf properties were recognized for environmental management practices by The Audubon Cooperative Sanctuary Program for Golf.
Powering a More Resilient Planet Together
From forest restoration projects designed to help strengthen watersheds to protecting the coastlines and marine species that make our oceans thrive, the story is the same: our power is greatest when we act together. This Earth Day, we’re celebrating the associates, guests, owners, members and community partners who are helping to protect biodiversity around the world and are dedicated to continuing to help our planet thrive.
“We remain committed to being thoughtful about how we build, operate, and engage with community stakeholders so our hotels can reduce their environmental impact while continuing to support local ecosystems around the world.”
– Robert Guidice, Chief Operations Officer, Marriott International
We believe that each tree planted, shoreline restored, and habitat protected brings Marriott closer to our 2030 Serve 360 goal of 35,000 nature‑positive activities – and reinforces the company’s belief that hospitality can be a force for good.
