Frequently Asked Questions
Why does beef have such a high carbon footprint?
Beef production requires large amounts of land, water, and feed. Cattle also produce methane through digestion (enteric fermentation), a greenhouse gas 28x more potent than CO2 over 100 years.
How much CO2 can I save by going vegetarian?
Switching from a heavy meat diet to vegetarian can save approximately 0.5-0.8 metric tons of CO2 per year. Going fully vegan saves even more, up to 1.5 tons annually.
