17 Dec 2018 --- Organically farmed food has a bigger climate impact than conventionally farmed food due to the greater areas of land required, according to a new study. Researchers have developed a new method for assessing the climate impact from land-use, and used this, along with other methods, to compare organic and conventional food production. The results show that organic food can result in much greater emissions. But some points of the study are being challenged by advocates in the organic farming sector.
