In a recent report of the World Economic Forum and McKinsey it was estimated that Natural Climate Solutions have the potential to deliver up to one third of the net-emission reduction required to stay on track for a 1,5-2 degrees scenario by 2030. A large part of that reduction potential (60%) comes from avoided deforestation, while only 15% comes from reforestation. This reflects the fact that avoided deforestation offers up to nine times as much potential low-cost abatement as reforestation.
