One Tree Planted is a 501c3 non-profit organization dedicated to global reforestation. The organization makes it simple for anyone to help the environment and support healthy forests. All of One Tree Planted's projects are guided by the following six pillars of reforestation: air, water, biodiversity, social impact, health and climate. To achieve their impact, they collaborate with over 266 incredible reforestation partners, make an impact in over 80 countries and communities, and have planted over 100,000,000 trees.

SeaTrees protects and restores coastal ecosystems to protect ocean health and fight climate change. The organization works with communities around the world to plant and protect mangrove and kelp forests, seagrass meadows, coral reefs, and coastal watersheds. The regeneration and protection of these ecosystems provide critical habitat for countless species, sustainable long-term employment for local communities, and protect communities from storm surges and sea-level rise.

Oceana, the world's largest international organization focused exclusively on ocean conservation, was founded in 2001 by a group of leading foundations concerned that although the oceans constitute over 70 percent of the earth's surface, an extremely small percentage of environmental funding was dedicated to protecting them.  Oceana's campaigns are designed to change that by forcing clear, identifiable policy changes with real "in the water" results, usually in three to five years. Our international campaigns in North America, Europe, Chile, and Belize are focused on the actions agreed on by scientists throughout the world as necessary to preserve and restore marine life: Protect seafloor habitat from destructive bottom trawling; Set and enforce reasonable catch limits for commercial fishing; Stop subsidizing overcapacity in commercial fishing fleets; Stop marine pollution, particularly carbon dioxide emissions that are making the oceans more acidic; Oceana sets annual goals toward achieving specific changes and holds itself strictly accountable to its Board, funders, and supporters.  Since inception, Oceana has achieved dramatic success in protecting the world's oceans in targeted, practical ways.

WWF's mission is the conservation of nature. Using the best available scientific knowledge and advancing that knowledge where we can, we work to preserve the diversity and abundance of life on Earth and the health of ecological systems by protecting natural areas and wild populations of plants and animals, including endangered species; promoting sustainable approaches to the use of renewable natural resources; and promoting more efficient use of resources and energy and the maximum reduction of pollution. We are committed to reversing the degradation of our planet's natural environment and to building a future in which human needs are met in harmony with nature. We recognize the critical relevance of human numbers, poverty and consumption patterns to meeting these goals.

The Nature Conservancy is a global environmental nonprofit working to create a world where people and nature can thrive. Its mission is to conserve the lands and waters on which all life depends, by boldly addressing the biodiversity and climate crisis over the next decade, and maximizing the organization's ability to effect change between now and 2030, to shape a brighter future for people and our planet.

Since its founding in 1875, American Forests has pledged to be the pathfinders for creating healthy forests from coast to coast. The nonprofit organization seeks to create healthy and resilient forests, from cities to large natural landscapes, that deliver essential benefits for climate, people, water and wildlife. The organization advances its mission through forestry innovation, place-based partnerships to plant and restore forests, and movement building.

Around the world, modern and industrialized farming practices are destroying the environment—and, at the same time, failing to provide reliable income and nourishment for the farmers we all depend on to survive. At Trees for the Future (TREES), we recognize that unsustainable land use is the root cause of our most pressing challenges. We confront these challenges by serving the people at the heart of our global food systems: farmers and their families. As a global leader in agroforestry training for over 30 years, TREES provides hands-on, immersive education, skill building, and support, encouraging farmers to work with nature, not against it. Our signature methodology, the Forest Garden Approach, helps farmers transform their land with thousands of fast-growing, ecologically appropriate trees and dozens of other crops, creating new possibilities for themselves and their communities. By embracing sustainable land practices, farmers are reclaiming their agency, breaking the cycles of climate change and generational poverty, and rebuilding our food systems from the ground up.

We inspire people to plant, nurture, and celebrate trees. Founded in 1972, the Arbor Day Foundation’s mission is simple: we inspire people to plant, nurture, and celebrate trees. This mission is the driving force behind all of our work in community forestry, large-scale forest restoration, rain forest preservation, disaster recovery, and education. We are proud to be the largest nonprofit conservation organization dedicated to planting trees. The impact we make is possible thanks to more than 1 million members and corporate partners as well as a strong global network of dedicated programmatic partners.
