What is Plant a Billion Trees?

The Nature Conservancy's Plant a Billion Trees campaign is a major forest restoration program. Our goal is to plant a billion trees across the planet to slow the connected crises of climate change and biodiversity loss.

A BILLION BEGINS WITH ONE (1:26) A lot can change in a lifetime, including the planet we live on. For better, or for worse. But we have the power to restore balance. Helping our planet is bigger than us, but it starts with each of us. Help us plant, protect, and restore forests by planting your tree today.

Why are we planting a billion trees?

Trees provide so many benefits to our everyday lives. They filter clean air, provide fresh drinking water, help curb climate change, and create homes for thousands of species of plants and animals.

Planting a billion trees can help save the Earth from climate change and biodiversity loss. When we restore and conserve critical forests, we remove carbon and support biodiversity. A billion is a big number, but we know we can do it together. Help plant trees today!

General Information

  • What is the Plant a Billion Trees Campaign?

    The Plant a Billion Trees campaign is a large-scale restoration initiative launched by The Nature Conservancy in 2008. Our first project was to restore Brazil's Atlantic Forest, and now we have expanded to include forest projects all across the world! By planting trees and helping forests regrow where they have been severely degraded, we're helping to reduce the impacts of climate change, slow biodiversity loss, ensure clean water and air for everyone, and provide full, healthy forests for future generations.

  • How does restoring and protecting forests impact me and communities around the world?

    Forests help sustain all life on Earth. They clean our water. Cleanse our air. Cool our planet. Store our carbon. Trees give us refuge and refreshment, shade and shelter.

    The Plant a Billion Trees campaign will help restore the health of our natural environments. Planting trees will improve important watersheds that provide clean drinking water and hydroelectricity to millions of people, as well as protect thousands of species of plants and animals.

  • One billion trees is a pretty big goal—how is TNC going to accomplish this?

    It is ambitious, but forests around the world are worth the effort. They are essential to healthy lives and planet. We will need to stretch in ways that challenge us and deepen our partnerships around the world. Together, we can achieve more than any of us can alone.

    TNC has over 400 scientists on staff that specialize in a range of different fields including forest ecology, water, climate mitigation, soil, carbon and other related areas. They are working to find the best ways to ensure the forests we restore and re-establish are viable ecosystems that provide multiple benefits to people and nature.

    Founded in 1951, because of donations like yours, The Nature Conservancy has the means, experience and track record to work closely with partner organizations to meet this important goal.

More Details

  • How much does it cost to plant a tree?

    The cost to plant a tree varies depending on the location of the project and the type of tree being planted, and ranges between approximately $1.50-$3 USD per tree. Beyond covering costs to simply plant the seedlings in the ground, donations support ongoing maintenance, research, and stewardship at Plant a Billion sites to ensure the seedlings grow to be mature, healthy trees.

    Donations also help pay for the reforestation efforts at PBT projects, such as the removal of invasive species, protecting areas where tree saplings are growing, encouraging species to return to degraded areas, and removing any barriers that might prevent a forest from regrowth. Up to 20% of the cost is used to help administer the program.

  • How are trees being cared for after they are planted?

    Monitoring procedures vary from site to site, but generally, TNC staff conduct regular site visits to oversee qualitative and quantitative surveys. We gauge measures such as seedling survival rates and tree sizes, as well as assessing ecosystem conditions for invasive/competing species to ensure we are making the appropriate adjustments to best care for our trees over time.

  • How is TNC staff involved at these projects?

    TNC staff and scientists, based in-country, manage each of our planting projects. To help accomplish this work, we collaborate with a network of in-country partners—including governments, forestry companies, local cooperatives, non-governmental organizations and local communities. Additionally, we offer assistance and technical guidance to others, using established TNC projects as a model to accelerate results and efficiencies.

  • Does TNC work with Indigenous Peoples and other local communities in the planting process?

    Partnering with Indigenous Peoples and local communities has been an important part of TNC’s approach for many years. Our partnerships with Indigenous Peoples and local communities are opportunities for mutual learning, sharing and benefit between the communities and TNC. We strive for transformational—not transactional—partnerships in the spirit of reciprocity. We learn from and support their leadership in stewarding their lands and shaping their future.

    Plant a Billion Trees, in particular, works very closely with Indigenous communities at our planting sites in Mexico and Brazil, which are homes to, respectively, the Mayan Forest and the Amazon. Through continued and expanded partnerships, TNC envisions strong indigenous organizations and peoples sustainably managing their lands, while collaborating with governments and other organizations to guarantee the integrity of those areas for future generations.

  • Does The Nature Conservancy provide carbon credits?

    Our Plant a Billion Trees reforestation projects yield important carbon benefits by capturing and storing carbon, helping to stabilize our climate. However, these projects do not offer certified carbon credits or offsets. TNC does offer a Carbon Calculator to estimate your carbon footprint. You can read more about carbon markets and their effects on climate change here.
