> A 2019 study of the global potential for tree restoration showed that there is space for at least 9 million km^2 of new forests worldwide, which is a 25% increase from current conditions. This forested area could store up to 205 gigatons of carbon or 25% of the atmosphere's current carbon pool by reducing CO2 in the atmosphere and introducing more O2.

Due to trees being dark, afforestation has a weaker impact on climate change than the stored carbon would make you think. They also evaporate a lot of water, which is also a GHG.
