Specific facts and statistics related to TreeClicks

In short: TreeClicks is a browser extension that plants trees for free when you buy at one of the more than 50,000 connected online stores. Shopping prices remain the same Here are some fun facts:

Online shopping in the USA: 600 billion dollar

  • Online shopping (e-commerce) in the USA accounts for more than 600 billion dollars in 2019.
  • If those purchases are also made with TreeClicks activated, we could plant billions of trees.
  • This equals an area the size of the whole of Ireland (see infographic below).

Current statistics

  • To date we have planted 6627 trees.
  • There are 2559 trees in planting. We expect to plant these, but some still could be canceled. For example, because someone sends a package back.
  • 30 euros = 1 tree: For an average of every 30 euros you spend at TreeClicks, we will plant 1 tree
  • More than 50,000 online stores are affiliated with TreeClicks.

  • The RMTRR maintains a list of dozens of trees older than 1,000 years.

  • Measured by volume, the General Sherman tree in California's Sekoia National Forest in America is the biggest tree in the world.
  • The widest tree in the world is the Sunland Baobab in South Africa with a diameter of more than 10 meters.


Statistics and facts related to deforestation and reforestation


  • Deforestation contributes to at least 10% of global CO2 emissions.
  • "Every year, 6.5 million hectares of natural forest disappear, which equals 17 soccer fields per minute." (WWF)
  • The World Wildlife Fund (WWF) estimates that more than 27 percent of the Amazon biome is out of forest in 2030.
  • Also in Europe, nearly half of the tree species are endangered (Scientias and Rivers, 2019).
  • Where tropical forests used to occupy 12 percent of the land area, today it is only 5 percent (Drawdown).
  • Deforestation is still ongoing in most places, but recovery is a trend in some places (Drawdown).
  • According to the World Resource Institute (WRI), more than 30 percent of the world's forest landscapes have disappeared and another 20 percent are in poor condition. An area of more than 2 million hectares (larger than South America) could be reforested again (Drawdown).


  • Various goals have been set, such as the Bonn Challenge: an initiative to restore 350 million hectares by 2030, which would absorb 12 to 35 billion tons of CO2. That equates to 6 to 12 months of worldwide CO2 emissions (Drawdown and TreeClicks calculations).
  • Restoring 350 million hectares of forest would cost about $350 billion to $1,000 billion. That sounds a lot, but we would earn a lot more in return. The International Union for Conservation of Nature estimates that we would get back $170 billion a year net, bringing benefits from water management, improved crop yields, and forest products (Drawdown).
