American’s love for beef blamed for higher food-related greenhouse emission
A recent study conducted by researchers at the University of Michigan Center for Sustainable Systems in the School for Environment and Sustainability and Tulane University showed that an estimated 20 percent of Americans were reponsible for food-related greenhouse emissions in mainland United States.
The survey, which focused on dietary choices at any given day of some 16,000 American adults, aims to assess the negative environmental impacts of food production.
Researchers found that a fifth of the population accounted for 46 percent of diet-related greenhouse emission with a regular intake of food with high carbon footprint.
Out of the 300 food types included in the study, beef consumption accounted for 72 percent of greenhouse emission; while less animal-based and low calorie foods account less to greenhouse build up, the paper which was published in Environmental Research Letters on March 20.
The experts, however, clarified that the study only involves food production-related emmissions. It does not included distribution, production, packaging, refrigeration and cooking of the food, which may add another 30 percent to the greenhouse emission.
