The Intergovernmental Panel on Climate Change (IPCC) scenarios for emission reductions are clear. In order to keep temperature rise close to the Paris Agreement goal of 1.5°C we must achieve net zero CO2 emissions by 2050. The scenarios show that this will require, in addition to a massive and rapid decarbonization, a significant contribution from landbased options. Nature-based solutions provide the best way of delivering these land-based options, through protection, restoration and sustainable management of natural carbon sinks and reservoirs. Moreover, there is additional mitigation potential from nature-based solutions in coastal and marine ecosystems.
