Experts analysed 73 urban and peri-urban agricultural facilities in America, Europe and Britain, assessing the life cycle of infrastructure, irrigation and supply of these facilities. As a result, the researchers concluded that the carbon footprint of food from urban and peri-urban gardens is six times greater than that of conventional agriculture – 420 grams of carbon versus 70 grams per serving of food.
The infrastructure used to grow food emits the most carbon. The scientists who conducted the study advise banning private vegetable gardens.
