The restoration of trees remains among the most effective strategies for climate change mitigation. The global potential tree coverage is mapped at 4.4 billion hectares of canopy cover which could exist under the current climate.

Excluding existing trees and agricultural and urban areas, there is room for an extra 0.9 billion hectares of canopy cover, which could store 205 giga-tonnes of carbon in areas that would naturally support woodlands and forests.

However, climate change will alter this potential tree coverage. It is estimated that if we cannot deviate from the current trajectory, the global potential canopy cover may shrink by ~223 million hectares by 2050, with the vast majority of losses occurring in the tropics.
