Dishes with a CO2e (or "CO2 equivalent") level of 0.6kg or lower, such as a sweet potato burrito (0.46kg), are labelled "low carbon". If they have a carbon footprint between 0.6kg and 1.6kg of CO2e, such as a grilled chicken club quesadilla, they are "medium-carbon". Any dishes with a higher footprint, such as a chargrilled steak burrito (3.04kg CO2e), are tagged "high-carbon".
