Celebrating the good Marriott International grew in 2025

Marriott International continues to show what environmental leadership looks like through work that transforms places today and decades from now. 

A year of partnership and progress with Marriott International

Leaders like Marriott International make planting trees at a meaningful scale possible. As this year's planting season gets underway, we're taking a moment to celebrate the progress we're building on from 2025.

Environmental leadership has never been more vital. The impact we make through trees and the scale at which we can plant is made possible thanks to corporations that care.

Last year was a powerful reminder of what is possible when two like-minded companies come together around a shared vision. Our partnership goes far beyond transactional work. It is rooted in celebrating the power of collective action to create lasting environmental change and building a legacy for those who will inherit this Earth for generations to come. Through a season of change, we are grateful to see one thing never waver: the commitment Marriott has to our shared world and to the impact we can make together.

Our mission is to inspire people to plant, nurture, and celebrate trees, and Marriott helps us do just that. While we planted trees together, we also help hundreds of people plant hope, love, and lasting memories. This impact is made possible because the Arbor Day Foundation and Marriott came together with purpose and intention.

Together, we are truly investing in a better world. We are deeply grateful to be on this journey with you and excited for all that lies ahead. Here’s to 2026 and the continued impact we are creating together.
