Data on GHG emissions from the global food system are often scattered and unavailable, but EDGAR-FOOD provides a consistent database from 1990 to 2015. The largest contributions to food-system emissions come from agriculture and supply chain activities, representing 34% of total global GHG emissions.
Data on GHG emissions from the food system are mostly scattered across sectors and remain unavailable in many countries. EDGAR-FOOD, a globally consistent food emission database, brings together emissions from food-related land use and land-use change, production, processing, distribution, consumption and residues over 1990-2015 at country level. We have developed a new global food emissions database (EDGAR-FOOD) estimating greenhouse gas (GHG; CO2, CH4, N2O, fluorinated gases) emissions for the years 1990-2015, building on the Emissions Database of Global Atmospheric Research (EDGAR), complemented with land use/land-use change emissions from the FAOSTAT emissions database. EDGAR-FOOD provides a complete and consistent database in time and space of GHG emissions from the global food system, from production to consumption, including processing, transport and packaging. It responds to the lack of detailed data for many countries by providing sectoral contributions to food-system emissions that are essential for the design of effective mitigation actions. In 2015, food-system emissions amounted to 18 Gt CO2 equivalent per year globally, representing 34% of total GHG emissions. The largest contribution came from agriculture and land use/land-use change activities (71%), with the remaining were from supply chain activities: retail, transport, consumption, fuel production, waste management, industrial processes and packaging. Temporal trends and regional contributions of GHG emissions from the food system are also discussed.
