Percentage change in environmental impacts for different diet scenarios worldwide in 2030. Environmental impacts were estimated using a model that combines regional food consumption, production and country-specific environmental footprints for greenhouse gas emissions, cropland use, freshwater use, and nitrogen and phosphorus application, taking into account trade, feed, and processing of primary commodities. The model was calibrated using data from the IMPACT agriculture–economic model. Adapted from reference 15 with permission under the terms of the Creative Commons CC-BY license.
