Additional file 1: Table S1. of Diet-related greenhouse gas emissions assessed by a food frequency questionnaire and validated using 7-day weighed food records

Data from life cycle assessment (LCA) studies expressed as carbon dioxide equivalents (CO2e) per kg of food product. Fig. S1. Scatter plot with crude CO2e assessed by Meal-Q on the vertical axis and crude CO2e assessed by WFR on the horizontal axis, for participants included in the validation analysis. Fig. S2. Bland-Altman plot showing the difference in crude CO2e assessed by Meal-Q and the WFR plotted against the mean of the two methods, for participants included in the validation analysis. Fig. S3. Scatter plot with crude CO2e assessed by the first Meal-Q on the vertical axis and crude CO2e assessed by the second Meal-Q on the horizontal axis, for participants included in the reproducibility analysis. Fig. S4. Bland-Altman plot showing the difference in crude CO2e assessed by the first and second Meal-Q plotted against the mean of the two methods, for participants included in the reproducibility analysis.
