I feel like the world is constantly conspiring to get me to eat bacon. That was my first thought when I saw this new study from France claiming that a plant-based diet is not actually the planet-saver we all thought. (My second thought was: WTF, I don't want to eat bacon.)
The study followed nearly 2,000 diners who self-reported their meals to scientists at the National Research Institute of Agronomy in Marseille; the researchers then tried to determine how much greenhouse gas was emitted in production of the most commonly consumed foods. Let the fuzzy math ensue! Reuters reports:
Overall, about 1,600 grams of carbon dioxide were emitted for every 100 grams of meat produced. That's more than 14 times the amount of greenhouse gas emitted during the production of fruit, vegetables and starches. It's also about 2.5 times as much greenhouse gas as that generated by fish, pork, poultry and eggs.
That gap narrowed, however, when the researchers looked at how many grams of carbon dioxide were emitted per 100 kilocalories (kcal) -- a measure of energy in food.
The most greenhouse gas -- 857 grams -- was still emitted to produce 100 kcal of meat, but it was only about three times the emissions from a comparable amount of energy from fruit and vegetables.
Wait wait, hold on, Reuters -- the lede of your article says that a plant-based diet "might not be the greenest in its environmental impact." Now you're telling me it's only three times better? Oh, wait, and now you're telling me it's no better at all?
