This is how it works

When a tree grows it absorbs CO2 and releases oxygen back to the atmosphere. This is part of the photosynthesis, the process by which trees use energy from the sunlight to produce glucose from CO2 and water. 

The absorbed CO2 is stored in the biomass, the roots, branches and stem of the tree. About half of the wood in a tree is pure carbon.

Trees capture CO2 from the atmosphere and convert it to biomass when growing.

We have developed a unique calculation method for estimating the carbon sink capacity of trees planted in our projects. In our algorithm errors and risks are included, making sure that we are planting at least the number of trees needed to cover for the CO2 emissions of our customers.

The calculation method is project-specific. In our forestation project in Tanzania we have considered harsh weather conditions, the risk of grazing animals and possibility of sustainable forestry. We want to support the local community and allow for the people to have access to the forests in all our African projects.

Grazing animals can be a risk for tree planting projects.
