The figures are based on 75 peer-reviewed studies and on test sites throughout the world where organic and conventional methods are compared side by side. These include Rodale’s long-running Farming Systems Trial (FST) in the United States and more recent Tropical Farming Systems Trial in Costa Rica. Rodale uses this data to calculate a rate of carbon sequestration per area of land cultivated, and then scale-up to see the impact of global adoption of each practice. For example, if all current cropland were cultivated using methods tested in Iran and Egypt, 21 gigatons of carbon dioxide equivalent (GtCO₂e), or 40 percent of global emissions, could be sequestered annually. If applied to the world’s pasture and grassland, Rodale calculates its recommendations could sequester 37 GtCO₂e, or over 70 percent of emissions. Changing the cultivation of cropland, pasture, and grassland together could lead to a net reduction in the greenhouse gases in our atmosphere via Plant Logic
