Agricultural Greenhouse Gas Study Accounts for Subsector Emissions
University of Illinois Urbana-Champaign led a location-specific study that accounted for net carbon dioxide, methane, and nitrous oxide emissions from all subsectors related to food production and consumption. The study results could help identify the primary plant- and animal-based food sectors contributing major greenhouse gas emissions and guide policymakers in taking effective action to reduce the highest emissions at each location. The findings are available in an open-access database. The study found that food-based agriculture accounts for 35% of all human-made greenhouse gas emissions. Of that, plant-based foods emissions contribute 29%, animal-based food emissions contribute 57%, and nonfood utilization such as cotton and rubber production contributes 14%.
