Potential for low-cost carbon dioxide removal through tropical reforestation (Nature Climate Change) Removing CO2 from the atmosphere by planting tropical forests could be a “low cost” way of tackling climate change, a study says. The research estimates that CO2 removal from tropical reforestation could be increased by 5% at a cost of $20 per tonne of CO2. However, “avoided deforestation” – leaving forests intact – could be up to nine times more cost effective than reforestation overall, the study finds.
