Underlying Data

All 38 food items with their carbon footprint and nutritional values per 100g. Data sourced from USDA Food Data Central and Our World in Data emissions research.

Food Item Category CO₂eq (kg) Calories Protein (g) Carbs (g) Fat (g)

Fat per 100g of Food Items

A horizontal bar chart comparing fat content across all food items. Nuts and groundnuts stand out as the highest fat foods, while most vegetables, fruits, and grains contain minimal fat.

Vertical bar chart showing CO2 equivalent emissions per kg for each food item. Beef leads at 99.48 kg CO2eq, with most plant foods clustered near zero.

CO₂ Equivalent (kg) per Food Item

A horizontal column chart showing the carbon footprint for all 38 items. Beef from the beef herd dominates at nearly 100 kg CO₂eq, roughly 10× higher than the next highest items, illustrating the outsized climate impact of ruminant meat production.

Horizontal bar chart showing fat per 100g for each food item. Nuts top the chart at 51.45g, followed by groundnuts at 49.2g and dark chocolate at 42.6g.

What the data tells us

231×
Beef emits 231× more CO₂eq per kg than potatoes, the most widely consumed staple vegetable in the dataset.
Top 5
The 5 highest-emission foods — beef, lamb, coffee, cheese, and prawns — are all animal products or heavily processed goods.
3% cost
Groundnuts deliver nearly as much protein as beef (25.8g vs 20g) at just 3% of beef's carbon footprint.
