Thai Airways is revamping their in-flight menu, but it has absolutely nothing to do with the food. The airline is actually adding carbon footprint information to their menus, so that travelers will know exactly what comes with that Chicken Mussaman Curry. There’s nothing like a side of guilt to go along with the vegetables.

The airline is participating in the Carbon Footprint Technical Cooperation Project for Thai Products. Here, Thai companies are sharing carbon footprint information in hopes of lowering energy usage while letting the world know that they mean business when it comes to green goods. Just so you're aware, if you decide to go with the Green Curry with steamed Thai Hom Mali Rice on your next flight it will set you back 13.9 kg CO2 e per 250g serving.
