Consuming meat as part of your diet increases your carbon footprint by a large factor. It take a lot more energy to produce meat than it does to produce plants. Indeed, many institutions have called for people around the world to consume less meat while increasing their fruits and veggies intake.
China has issued new dietary guidelines that encourage less meat consumption in hopes that it frees up resources (land, energy, etc.) for other means. Given the size of China’s population even a small percentage of Chinese changing their diets will make a difference.
New dietary guidelines drawn up by Chinaâ€™s health ministry recommend that the nationâ€™s 1.3 billion population should consume between 40g to 75g of meat per person each day. The measures, released once every 10 years, are designed to improve public health but could also provide a significant cut to greenhouse gas emissions.
Should the new guidelines be followed, carbon dioxide equivalent emissions from Chinaâ€™s livestock industry would be reduced by 1bn tonnes by 2030, from a projected 1.8bn tonnes in that year.
Globally, 14.5% of planet-warming emissions emanate from the keeping and eating of cows, chickens, pigs and other animals â€“ more than the emissions from the entire transport sector. Livestock emit methane, a highly potent greenhouse gas, while land clearing and fertilizers release large quantities of carbon.
