What is the basis for the goal to conserve, restore, and grow a trillion trees globally by 2030?

This goal is based on several bodies of scientific research that suggest that forests are a key component of addressing the global challenges of climate change, biodiversity loss, and their consequences for human livelihoods and well-being.

The goal to conserve, restore, and grow 1 trillion trees by 2030 is a global objective for the restoration community. Support for this target includes research led by ETH Zurich/Crowther Lab indicating that there were nearly 6 trillion trees on our planet prior to the Agricultural Revolution 12,000 years ago. Today, it’s estimated that only half remain.

Is 1t.org only focused on planting new trees?


Our mantra is “conserve, restore, grow”. We’ve chosen that order for a reason. The foundation for forest conservation is to maintain existing, healthy forests as forests. The next best option for carbon sequestration, maintaining biodiversity, and all the other benefits that trees provide (water capture, healthy soils, climate regulation, etc.) is to restore degraded forests. This can either be through natural regeneration (leaving forests to recover on their own) or through assisted regeneration (i.e. through the removal of old infrastructure that may inhibit tree growth).

Lastly, we emphasize the word “grow” instead of “plant”. Tree planting initiatives are a key part of reforestation commitments and essential in areas that are too degraded to recover on their own. We use “grow” to emphasize that simply putting a seedling in the ground is not sufficient – that tree needs to be supported to maturity to reach its full potential. It also needs to be the right species, planted in the right conditions.

Why do we need forests?

The degradation and loss of forests is destabilizing natural systems on a scale never seen in human history. We have already lost nearly half of the trees that existed before the onset of agriculture, and this loss continues to grow every year from both human and climate impacts.

Forests are essential to people, nature, climate and the economy:


1.5 billion people depend on forests for employment, wellbeing, food, water, wood and other products.

60 million Indigenous people live in and rely on the tropical rainforests of South America, Asia and Africa.


Forests are home to over half of the world’s terrestrial biodiversity, including many endemic species found only in forests.

They recharge groundwater, filter air, support fertile soil and act as flood barriers.

For example, recycling of water by the Amazon rainforest generates 30-40% of the region’s rainfall.


The world’s forests store 861 billion tonnes (Gt) of carbon – nearly a century’s worth of current annual fossil fuel emissions.

Conserving old-growth forests is essential. WWF has found that preventing the loss of one hectare of mature, carbon- and biodiversity-rich forests will typically avoid emissions of about 100 tonnes of carbon.

Forests also continue to absorb carbon dioxide and regulate global temperatures.


Over half of global GDP – $44 trillion – is at risk from nature loss, including forests, due to nature's resources and services.

A recent study found that every $1 (both private and public investment) spent on key net-zero and nature-positive activities, including ecosystem conservation and restoration, can generate up to $7 more in the broader economy.

Can we solve climate change by planting trees?

No, absolutely not.

To address climate change we must first rapidly and significantly decarbonize across all sectors of industry and economic activity.

In addition to that, healthy forest ecosystems can make a substantial contribution toward addressing climate change. One mature tree can capture an average of 0.62 metric tons of carbon dioxide equivalent (CO2e) over its lifetime. That is equivalent to the carbon emissions from driving one car 2,400 kilometers. In the U.S. for example, forests and forest products currently capture and store 15% of U.S carbon dioxide emissions from fossil fuel combustion each year, and research suggests this could be doubled through sensible forestry practices.

It is not a simple either/or scenario. To address climate change we need to decarbonize our economy and we need to protect and restore our forests.

The latest science by Crowther Lab highlights that natural forests are no substitute for cutting greenhouse gas emissions or phasing out fossil fuels, but they are part of the solution. The data show that if forests are allowed to recover, they could capture approximately an additional 226 Gt Carbon. Read more on this science here.

Furthermore, forests are absolutely critical to maintaining biodiversity and the ecosystem services upon which our livelihoods depend, which are being severely threatened by increased nature loss. Hence their conservation and restoration are needed regardless of the role they play in climate mitigation, to bring us onto a nature-positive trajectory.

How can 1t.org’s vision be met by 2030?

This ambitious target can be met through actions that conserve forests that already exist, slow deforestation, help restore degraded forests, and grow the right tree species in the right places.

1.torg has been designed to serve the global trillion trees community. We aim to empower organizations and individuals to more effectively undertake needed actions so we can collectively achieve the trillion trees vision.

These activities include:

  • Permanent conservation of existing trees and forests, such as placing areas of old growth and primary ecosystems under protection
  • Restoring and growing trees, including passive forest regeneration, reforestation of degraded forest lands, appropriate tree-planting schemes on suitable agricultural land (such as agroforestry), and urban tree planting
  • Supporting activities for trillion trees that enable the entire 1t.org community to build better systems to further catalyze progress, such as nursery development, technology tools, technical assistance, markets and innovation, capacity building, and workforce development

Do you accept mangroves pledges?

Yes. Blue carbon ecosystems such as mangroves, seagrasses and salt marshes store up to five times more carbon per acre than tropical rainforests while also supporting food security, livelihoods, storm protection, and biodiversity. It is estimated that the blue carbon market could potentially be worth billions of dollars, offering an opportunity to invest in people, nature, and climate through the conservation and restoration of blue carbon ecosystems.

How does 1t.org work to ensure responsible forestry practices are maintained?

The success of conserving, restoring, and growing forests requires following ecologically sound principles—such as only planting trees in landscapes where they are ecologically appropriate, and ensuring that biodiversity is maintained or enhanced. Converting treeless native grasslands into forests, for example, would create ecological damage that overrides any environmental benefits the trees would provide.

Furthermore, forestry activities need to incorporate scientific and traditional knowledge considerations such as “the right tree in the right place”, and considerations for planting forests that can withstand future climate change stresses.

To help guide companies that are making commitments we provide best practice inputs, such as the IUCN Standard for Nature-Based Solutions, as resources to consider when developing appropriate approaches.

All companies (and other entities in the case of the US Chapter) making a commitment towards forest conservation, restoration or reforestation are encouraged to include a statement on how they plan to uphold responsible and equitable standards when implementing their pledge. This includes “ecologically appropriate and climate-informed forestry (e.g., right tree right place)” and “long-term stewardship and capacity.”

How can individuals get involved with 1t.org?

Youth groups can get engaged via the global youth hub that is being created in partnership with the UN Decade for Ecosystem restoration and the Global Landscapes Forum.

Is 1t.org collecting donations? Can 1t.org support my project?

1t.org is a platform to engage the reforestation community and can neither collect nor distribute donations.

There are many organizations active in the forest conservation and restoration space accepting individual donations, and we encourage you to find one that meets your goals.

If you have a project and are looking for donations, consider submitting your solution on the UpLink Trillion Trees Challenge, particularly if you are active in one of the regions where we engage, which will be running regional challenges sourcing solutions from the field.
