Fig 1.
Range of greenhouse gas emissions within categories and design of carbon labels for every restaurant.
kg CO2e = kilograms of carbon dioxide equivalents per dish.
Fig 2.
Modular dish (Oriental menu) with (a) and without (b) carbon labels. The upper image represents the high-emission default, the lower image represents the low-emission default.

Pearson correlations for dish choices, associated greenhouse gas emissions, and self-reported eating behavior.
Fig 4.
Number of high-, medium-, and low-emission dish choices in the presence (a) and absence (b) of carbon labels. HE = high emission, LE = low emission.

Results of the multinomial logit model analyses (last two models) on high- and low-emission dish choices, compared with medium-emission dish choices.
Fig 5.
Mean emission per chosen dish in kilograms of carbon dioxide equivalents.
HE = high emission, LE = low emission.
