Organic farming vs conventional: Land use, emissions, and climate impact

Organic farming is often assumed to be greener than conventional farming, but a review of 100 comparative studies shows a more complex picture. Organic systems use less synthetic pesticides and support more local biodiversity, but they also require about 64 percent more land to produce the same amount of food. When measured per kilogram of food, greenhouse gas emissions are similar between organic and conventional methods. The bigger climate lever is diet. Swapping beef for plant proteins cuts emissions by orders of magnitude, far more than choosing organic over conventional produce. Food transport also plays a small role in overall emissions, except for air-freighted goods. For shoppers and policymakers focused on carbon footprints, what you eat and how much land the food uses matter more than the organic label alone.
