Plant Based Meats Do More to Address Climate Change Than Green Buildings or Zero-Emission Cars

My calculations show that in the future—by lowering the share of beef and raising the share of pork, chicken meat, eggs, and dairy products, by more efficient feeding, and by better use of crop residues and food processing by-products—we could match recent global meat output while greatly limiting livestock’s environmental impact, including its sha

“Shifting less than one day per week’s worth of calories from red meat and dairy products to chicken, fish, eggs, or a vegetable-based diet achieves more greenhouse-gas reduction than buying all locally sourced food,” they write.

by shifting the split to 40, 50, and 10 percent, we could (thanks to grain feed saved by reducing inefficient beef production) produce easily 30 percent more chicken meat and 20 percent more pork, while more than halving beef’s environmental burden—and still supplying at least 10 percent more meat.
