Per-Serving Emissions:
This calculation provides an estimate. Actual emissions may vary based on specific farming practices, transportation, and cooking methods.
The carbon footprint of a meal is calculated by summing the emissions from each ingredient, based on its mass and a specific emission factor, then adjusting for serving size.
The general formula used is: Total_g = sum(mass_g_i × factor_g_i); Final_Total_kg = (Total_g / 1000) × multiplier
Total_g = sum(mass_g_i × factor_g_i); Final_Total_kg = (Total_g / 1000) × multiplier
Consider a meal for two servings with 150g chicken, 50g rice, and 30g vegetables per serving.
This calculation provides an estimate of the meal's environmental impact.
Emissions vary based on production methods, land use, transportation, and processing required for each food item.
No, these are estimates. Actual footprints can vary due to regional differences, farming practices, and supply chain specifics.
Consider consuming less meat, choosing seasonal and local produce, and minimizing food waste.
