Measure the climate impact of your meat consumption.
Livestock production accounts for 14.5% of global greenhouse gas emissions (FAO). Beef is the most carbon-intensive common food: 27 kg CO2e per kg of meat — 100× more than most vegetables. This includes methane from enteric fermentation (cow burps), nitrous oxide from manure, deforestation for pasture, and feed production. A single kilogram of beef requires 15,400 liters of water and 7-10 kg of grain feed. Lamb is nearly as intensive at 24 kg CO2e/kg, while pork (6.1) and chicken (5.7) are significantly lower due to better feed conversion ratios. Replacing all meat with plant-based alternatives could reduce food-related emissions by 49%. Even replacing beef alone with chicken would cut dietary emissions by ~30%. The growing plant-based meat industry ($5 billion market) offers products with 90% lower emissions, 99% less water use, and 93% less land use compared to beef.
