The agriculture and food system accounts for 34% of greenhouse gas (GHG) emissions. France has committed to reducing GHG emissions by 46% by 2025. A joint study by the French Society of Nutrition (SFN) and the Climate Action Network (RAC) carried out by Nicole Darmon showed that a 50% reduction in meat consumption combined with an increase in the consumption of adequate vegetables reduces the carbon impact by 35% while satisfying nutritional recommendations for adults.
