The environmental impact of a plant-based vs. omnivorous diet
EMISSIONS CO2 / BBC Future Experiment, CO2 emissions in a week: - Vegan CO2e emissions per week: 9.9 kg - Vegetarian CO2e emissions per week: 16.9 kg - Omnivore CO2e emissions per week: 48.9 kg  - make it visually appealing What do these figures translate to in everyday terms? The U.S. Environmental Protection Agency's equivalence calculator provides some useful comparisons: - Vegan, 9.9 kg (21.8 pounds): Equivalent to driving 24.6 miles (39.6 km) in a gasoline car or charging 1204 smartphones. - Vegetarian, 16.9 kg (37.3 pounds): Equivalent to driving 41.9 miles (67.4 km) in a gasoline car or charging 2056 smartphones. - Omnivore, 48.9 kg (107.8 pounds): Equivalent to driving 121 miles (194.7 km) in a gasoline car or charging 5948 smartphones. WATER CONSUMPTION - It takes 725.6 liters of freshwater to produce 100g of beef protein, while tofu requires eight times less freshwater (92.9 liters) LAND CONSUMPTION - The Good Food Institute estimates that plant-based meat uses up to 99% less land than conventional meat. If everyone switched to plant-based diets, we could save up to 75% of the world's agricultural land GREENHOUSE GAS EMISSIONS (GHG) - A 2017 report by the Vegan Society reveals that just being vegan for one week can help each person avoid 14.7 kg of greenhouse gas emissions. CARBON FOOTPRINT - Adopting a vegan lifestyle reduces an individual's carbon footprint by 73% WASTE REDUCTION / PREPARED FOOD - Direct-to-consumer supply chains with prepared food kits reduce food waste (−0.86 kg CO2e/meal) and lower last-mile transportation emissions (−0.45 kg CO2e/meal), offsetting the increased CO2 consumption caused by packaging (0.17 kg CO2e/meal). Additionally, kit cooling packages show an average emissions decrease compared to retail cooling (−0.37 kg CO2e/meal).
