More than a million trees have been planted in the city of Freetown in Sierra Leone since 2020. This reforestation scheme, known as "FreetownTheTreeTown," has been celebrated for its innovative approach to climate action, with ambitious plans to plant another 5 million trees by 2030 and 20 million more by 2050.
