A study in Nature Communications highlights the potential for tree planting to inadvertently exacerbate climate change if not properly located.

Trees capture CO2, but inappropriate reforestation can reduce the albedo effect, leading to underestimation of climate benefits by 20-80%.

Optimal regions for tree planting include the Amazon and Congo basins, while reforesting areas like prairies and savannas may be harmful.

Research shows only 45% of current tree planting projects align with areas that offer the greatest potential for climate benefit.

The study advocates for a strategic approach to tree planting, ensuring that reforestation efforts are aligned with regions where they will be most effective.
