This article explores how forests can help reduce harmful gases that cause climate change by capturing and storing carbon dioxide. Tropical forests have the highest potential for capturing carbon, especially in Africa. The cost to enhance one ton of forest carbon storage can range from $0 to$443, with costs in tropical regions lower than elsewhere. Options like managing forests or planting new trees can significantly reduce the cost of cutting emissions, with planting trees being the cheapest option. Ultimately, using forests to store carbon is a cost-effective way to fight climate change by reducing harmful emissions.
