Common Food by Carbon Dioxide Emission per kg Food Produced

Food production is one of the main sources of global warming and stands for 14 % of total global carbon emission, food transportation excluded (Wikilists list of global greenhouse gas emission by source). The list below is a list of common food by carbon emission per kg food produced. The list is topped by animal products. The difference between the carbon emission from meat and vegetables is huge. It is possible to produce almost 150 kg carrots from less carbon emission than what it takes to produce one kg beef!
