How Many Trees Are Planted Globally: A Comprehensive Overview

Billions of trees are planted worldwide every year, but no one can give you an exact figure — and the more useful number, how many of those trees are still alive five years later, is almost never published at all. That gap between trees planted and trees surviving is the single most important thing to understand about global reforestation statistics.

What we can say with confidence

• The scale is genuinely large. Governments, NGOs, companies and individuals plant billions of trees annually across thousands of separate programmes.
• Nobody aggregates it reliably. There is no single global registry of planted trees, and methodologies differ between countries and organisations.
• Records exist for individual events. India set a world record by planting 66 million trees in a single day, and China's "Great Green Wall" has been running for decades to combat desertification.
• Survival is rarely reported. Planting figures are announced; survival rates usually are not, and that asymmetry is the reason the totals should be read carefully.

Why the number is so hard to pin down

Four practical problems make a global total unreliable:

1. No central register. Planting happens across national programmes, NGOs, corporate schemes and individual landowners, with no shared reporting standard.
2. Double counting. A single planting can be claimed by the funder, the implementing NGO and the host government, appearing three times in three sets of statistics.
3. Different definitions. Some counts include natural regeneration, agroforestry or crop trees; others only count restoration planting. The word "tree" is doing a lot of work.
4. Announcements versus outcomes. Pledges are reported when made. Whether the trees were planted, and whether they lived, is a separate question that rarely gets its own press release.

The number that actually matters

Trees planted is an input. Forest restored is an outcome, and the two can diverge dramatically. Large planting drives that skip maintenance frequently see substantial losses in the first few years, because survival is determined by what happens after the photographs are taken: watering through the first dry season, protection from grazing, replacement of failures, and species chosen for the site rather than for speed.

This is why a smaller, maintained programme can deliver more real forest than a much larger unmaintained one. If you are assessing any planting claim — a country's, a company's or a supplier's — the questions that matter are: how many survived, how was that measured, and who is paid to look after the site. The methods behind an honest answer are set out in how planted trees are verified.

Planting is not the only route to more forest

A point often missed in the numbers race: in many landscapes the cheapest and most biodiverse way to get forest back is to stop the pressure and let it return by itself. Natural regeneration produces no impressive planting statistic, which is part of why it is under-used, but where a seed source survives nearby it frequently outperforms planting on both cost and ecological outcome.

Planting earns its place where regeneration cannot happen unaided — degraded soil, no seed source, land that needs active intervention. The distinction between restoring lost forest and establishing new forest is covered in reforestation vs afforestation.

How to read a big planting number

• Ask over what period. "One million trees" across ten years is a different claim from one million this year.
• Ask where. Country, and ideally coordinates. Global totals without locations cannot be checked.
• Ask which species. A single fast-growing species is a plantation, not a restored forest.
• Ask about survival. If no survival rate is published, treat the planting figure as an intention rather than a result.
• Ask who maintains it. Maintenance budgets are the quiet difference between a forest and a field of dead sticks.

What this means if you are funding planting

Optimise for evidence rather than volume. A programme that can show you coordinates, species, monitored survival and the people paid to maintain the site is worth considerably more per pound than one offering the largest possible number of seedlings.

That is the model Evertreen is built on: trees from £1.5 each, every one GPS-geolocated, photographed and filmed in the field, planted and maintained by paid local teams, with conservative absorption estimates published in how we estimate tree CO₂. If you need audited tonnes for reporting, certified Verra and Gold Standard credits are available alongside the planting.

Frequently asked questions

How many trees are planted globally each year? Estimates run into the billions, but there is no authoritative global figure because no central register exists and methodologies differ between countries and organisations.

Why is there no exact number? Because of double counting between funders, implementers and governments, inconsistent definitions of what counts as a planted tree, and the gap between pledges and completed planting.

How many planted trees survive? It varies enormously with maintenance, species and site. Survival is decided mostly in the first three years, and unmaintained mass planting can lose a large share of its seedlings.

Which country plants the most trees? China and India run the largest programmes by volume, including China's long-running Great Green Wall and India's record of 66 million trees planted in a single day.

Is planting more trees always better? No. Trees planted on intact grassland or peatland can reduce biodiversity and release stored soil carbon, so where and which species matter more than how many.

What is better than planting in some cases? Natural regeneration, where a seed source survives nearby. It is often cheaper and more biodiverse, though it produces no headline planting figure.

How do I check a planting claim? Ask for the location, the species, the measured survival rate and the sampling method behind it, and who is paid to maintain the site.
