We love trees and believe many more should be planted. However, we need more trees AND we need direct air capture.
If done well, afforestation comes with several important benefits such as reduced soil erosion and increased biodiversity.
- A tree can only store CO2 over its lifetime (about 100 years in average)
- Human impact on climate and policy on forest have led to droughts, wildfires and deforestation that have affected the reliability and durability of the storage in trees and forests
- Afforestation cannot be scaled to the required levels because it requires lots of water and surface area
Carbon dioxide removal via direct air capture and storage is a complementary approach to planting trees. It is highly scalable as it requires only a small physical footprint and is fully measurable and permanent.
