Study: Plant-based Diets Have Potential to Reduce Diet-Related Land Use by 76%, Greenhouse Gas Emissions by 49%

A new study has found that “transitioning to plant-based diets has the potential to reduce diet-related land use by 76%, diet-related greenhouse gas emissions by 49%”.

The study, titled Plant-Based Dietary Patterns for Human and Planetary Health, also found that transition to plant-based diets can reduce “green and blue water use by 21% and 14%, respectively, whilst garnering substantial health co-benefits.”

Conducted by researchers at the University Hospitals Coventry & Warwickshire and the University of Warwick, the study was published in the journal Nutrients and was epublished by the U.S. National Institute of Health.

“The coronavirus pandemic has acted as a reset on global economies, providing us with the opportunity to build back greener and ensure global warming does not surpass 1.5 °C”, states the study’s abstract. “It is time for developed nations to commit to red meat reduction targets and shift to plant-based dietary patterns.”



Researchers follow this up by stating that “Transitioning to plant-based diets (PBDs) has the potential to reduce diet-related land use by 76%, diet-related greenhouse gas emissions by 49%, eutrophication by 49%, and green and blue water use by 21% and 14%, respectively, whilst garnering substantial health co-benefits.”

In addition, “An extensive body of data from prospective cohort studies and controlled trials supports the implementation of PBDs for obesity and chronic disease prevention. The consumption of diets high in fruits, vegetables, legumes, whole grains, nuts, fish, and unsaturated vegetable oils, and low in animal products, refined grains, and added sugars are associated with a lower risk of all-cause mortality.”

Researchers state that “Meat appreciation, health concerns, convenience, and expense are prominent barriers to PBDs. Strategic policy action is required to overcome these barriers and promote the implementation of healthy and sustainable PBDs.”
