Honestly, planting trees in tropical regions is most cost effective. So why don’t we plant trees there?
To have a positive impact on the climate, the long-term sustainability of trees is crucial. A freshly planted tree only absorbs small amounts of CO2 from the air. The bigger it grows the more CO2 it captures.
Just reducing CO2 emissions is no longer enough. Atmospheric CO2 levels have risen so much that even if the whole world lived carbon neutral from now on, climate change would continue.
Planting a tree is not very beneficial to the climate if it dies of dehydration, is caught in a wildfire or is cut down for more economically attractive farmland.
That’s why we plant trees in Germany. In Germany, forests are protected by the Bundeswaldgesetz (Federal Forest Act). Wildfires are quickly put out and illegal logging is prevented. In addition, should any trees be damaged, the owners of the forest are responsible for reforesting the affected areas.
Research from experts has made it clear. Despite new and promising technologies, the most efficient and cost effective climate protection measure is to simply plant trees.
