Why it matters

Since people began clearing land, the world has lost nearly half its trees, and the cutting hasn’t stopped.1 Growing them back draws carbon out of the air, rebuilds habitat for wildlife, and restores the soil and water that farms and towns depend on.

How we’ll know it’s done

Finish line
One trillion more trees growing than in 2020, when the 1t.org push began.2
What counts
A tree that survives, not a sapling planted.
How it’s checked
Survival counts on the ground and satellite maps of tree cover.
Our part
Every campaign reports the trees it planted each month.

What follows

  • Carbon drawn out of the air and stored in wood and soil.E-08Establish global climate equilibrium
  • Habitat for wildlife, and corridors that reconnect it.W-01Protect endangered and critical species
  • Roots that hold the soil and help rain soak in.E-06Regenerate the global topsoil
  • Food, fuel and income from trees on working farms.H-01Eliminate global hunger and malnutrition
  • Forested watersheds that keep rivers and wells clean.H-03Establish universal access to clean drinking water

How it can be solved

The approaches to this goal, and how many of the organizations taking each one we’ve vetted.

  • Agroforestry

    Trees planted among crops on working farms, so the land feeds families while it regenerates.

    3 organizations · 1 vetted

  • Mangrove and coastal restoration

    Replanting mangroves and coastal forests, which shelter shorelines and store carbon.

    1 organization · 1 vetted

  • Native forest restoration

    Bringing back the forest that belongs there, with native species chosen for the place.

    4 organizations

  • Community reforestation

    Local people paid and supported to grow, plant and protect trees.

    5 organizations · 2 no longer operating

  • Drone reforestation

    Drones that map degraded land and drop seed pods across it, faster than planting by hand.

    2 organizations · 1 no longer operating

  • Professional and post-fire planting

    Commercial crews and nurseries that replant at scale, often after wildfires.

    2 organizations

  • Wildlife corridors

    Replanting cleared land between forests, so wildlife can move between them again.

    1 organization

  • Planting platforms

    Platforms that fund tree planting by partner organizations around the world.

    4 organizations

  • Urban forestry

    Planting and caring for trees in cities, where they cool streets and clean the air.

    1 organization

Who’s working on it

We only call a solution proven, measurable and scalable once our vetting team has vetted it. Everything else here, the team is tracking.

Vetted2 organizationsReviewed by our vetting team, and passed all three tests.

  • Proven

    It has worked, with results to show.

  • Measurable

    Its impact can be counted.

  • Scalable

    It can grow toward the size of the goal.

Listing an organization isn’t an endorsement. Not vetted means just that: our vetting team is tracking it, and we make no claims about it yet. Last reviewed October 2026.
