The analysis relies on a modelling of land-sector development trajectories optimizing least-cost pathways, a bottom-up assessment of mitigation potentials, and a correction of potentials for political feasibility.
The Global Biosphere Management Integrated Assessment Model, a partial-equilibrium model developed by the International Institute for Applied Systems Analysis, formed the basis of the modelling.
The study determined the 40 countries with the highest technical mitigation potential and assessed the feasibility of mitigation action based on their political will and ability to realize this potential. Finally, the roadmap of action outlined 10 priority actions to reduce the land-use sector’s contribution to global warming. The actions range from avoided deforestation, restoration of forests, to diet shifts and reduced food waste.
