Why Kiri?

Kiri is the Japanese name for the ancient Paulownia tree, which absorbs CO2 up to ten times more than other tree species. This capability makes the Kiri tree unique and one acre of Kiri trees can absorb an astonishing 13 tons of CO2 gases and particles per year.

What's the Problem?

Global fossil fuel carbon emissions have increased by more than 140% since 1970 up until today. The air we breathe in daily is being polluted increasingly and, for us humans, air pollution is now the fifth leading risk factor for mortality worldwide. In 2017 alone, air pollution was the cause of 9% of all deaths in that year on the planet.

The greenhouse effect

Fossil fuel emissions are causing the climate to change rapidly and the earth's temperature to increase (the greenhouse effect). Air pollution negatively affects every level of the planet from human life to animals, plants, soil and oceans.

Why focus on CO2?

When looking at greenhouse gases, the primary one is carbon dioxide (CO2) and makes up around 76% of all greenhouse gases. Once emitted, its warming effect can be measured for hundreds of years, unlike other gases.

Positive reinforcement

Up to today, institutions have focused on prohibiting polluting behaviours. What is missing, is a positive approach to living sustainably and incentivising every one of us to make green choices daily. This is the reason Kiri was born. Together as a planet, we have to accelerate the adoption of sustainable behaviours. Join us today.

More about the Kiri Tree

Reforestation icon


The wood of the Kiri tree grows fast and is fire resistant. The tree could be planted in areas affected previously by fire.

Soil pollution icon

Soil Pollution

The Kiri tree can grow and thrive even on poor soils. By doing this, it improves and recovers previously polluted or damaged soil.

Tree food icon


Honey can be made from the flowers of the tree. The tree is a melliferous plant, increasing the spreading of bees, which are threatened by human activities.

Tree commerce icon


The Kiri tree grows fast and does not need a lot of water during its lifetime. The wood is light, does not bend, break easily or twist.

Tree medicine icon


Medical companies use the Kiri tree to produce medicines for liver, kidney and lung diseases.

Tree animal icon

Animal Feed

The large leaves contain a high nutritional value and can be used as food for animals.

Tree terrain icon


The Kiri tree can help to consolidate terrains with erosion. This is important in areas prone to landslides and to hydro-geological risk.
