Ten promising pathways to GHG emission reduction in the global food system

This paper reviews ten promising pathways to greenhouse gas (GHG) emission reduction in food systems: shifting diets; improving waste management, energy use in value chains, cold-chain efficiency; reducing enteric fermentation; improving manure management, fertilizer manufacturing emissions, rice cultivation, soil organic carbon; and encouraging agroforestry.

It assesses their technical and economic mitigation potentials, the synergies and trade-offs across mitigation options and development goals, as well as the stumbling blocks for implementation, and suggests ways forward. This paper highlights the potential of mitigation options like changes in diets and reduction of food losses and waste.
