The food miles calculator estimates CO₂ emissions from food transportation based on distance, transport mode, and food weight. Use food presets for popular imported items, or enter a custom origin distance. Air-freighted food produces up to 210× more transport emissions than sea freight. Use the Meal Comparison tab to calculate total food miles for an entire meal.

How to Use the Food Miles Calculator
This food miles calculator estimates the transportation CO₂ emissions of food items based on distance, weight, and transport mode. Use the quick presets to load values for popular imported foods like bananas from Ecuador (2,500 miles by sea) or strawberries from Spain (2,800 miles by air), or enter a custom distance for any food item. Switch to the Meal Comparison tab to calculate the combined food miles for an entire meal using 5 pre-built templates.
What Are Food Miles?
Food miles measure the distance food travels from farm (or production facility) to your plate. The concept gained attention in the 1990s as researchers began quantifying the energy cost of globalized food supply chains. A banana from Ecuador travels approximately 2,500 miles to reach a typical US grocery store, producing around 0.48 kg of CO₂ per kilogram of bananas shipped by sea. The same banana flown by air cargo would generate roughly 5 kg CO₂ per kilogram — more than 10 times higher.
Food miles matter because transportation accounts for roughly 6–10% of the total carbon footprint of our food system globally. While this is smaller than production emissions (especially for animal products), it's a factor consumers can directly influence through purchasing choices.
Why Transport Mode Matters More Than Distance
Air freight has a 210× higher emission factor than sea freight. Bananas shipped 5,000 miles by sea generate far less CO₂ than strawberries airfreighted 2,000 miles. The route visualization and mode comparison bars make this difference immediately clear. Winter strawberries from Spain arrive by air — a single serving generates more transport CO₂ than the same weight of bananas shipped across the Atlantic by container ship. The auto-detect mode selects a likely transport method based on distance and food type: perishable foods over 2,000 miles are likely air-freighted; durable goods travel by sea or rail; local produce typically uses road transport.
Food Miles vs Carbon Footprint
Food miles (transport distance) and carbon footprint (total emissions) are related but not the same. The most important factor in food's total carbon footprint is usually the production method, not the distance traveled. Beef produces about 27 kg of CO₂ per kilogram of food — regardless of where it comes from. Lentils produce about 0.9 kg CO₂ per kilogram. Even if you sourced local beef and imported lentils, the lentils would have a dramatically lower total footprint.
Shipping method also matters enormously. 1 kg of food shipped by air produces approximately 1.13 kg CO₂ per kilometer traveled, while the same food shipped by sea produces only 0.012 kg CO₂ per kilometer — a 94× difference. This is why sea-freight avocados from Mexico can have a lower transport footprint than locally delivered dairy products that require refrigerated road transport.
Using the Meal Comparison Mode
The Meal Comparison tab lets you analyze an entire meal's food-mile footprint. Choose from 5 pre-built templates (Summer BBQ, Thanksgiving Dinner, Weeknight Pasta, Taco Night, Sunday Roast) or build your own by adding individual items from the Single Item tab. Each template pre-fills typical ingredient weights and origin distances based on the most common US sources for those foods.
The seasonal comparison panel shows the same food item in-season vs out-of-season, revealing dramatic differences. For example, strawberries in June from a local US farm travel about 50 miles by road — versus strawberries in January from Chile traveling 5,800 miles by air. The out-of-season strawberries generate approximately 80× more transport CO₂. Choosing seasonal produce for perishable fruits and vegetables is one of the highest-impact food choices you can make.
How to Reduce Your Food Miles
The most effective strategies to reduce food transportation emissions: (1) Buy locally at farmers markets for seasonal fresh produce — this eliminates air freight on perishables. (2) Prioritize seasonal eating — in-season local strawberries vs out-of-season Chilean strawberries is often an 80× CO₂ difference in transport alone. (3) Choose sea-freight over air-freight foods — check if products like mangoes or asparagus are available in varieties that don't require air shipping. (4) Reduce animal product consumption — the production footprint dwarfs transport, so plant-based substitutions have more impact than choosing local vs imported. (5) Buy dry goods in bulk — grains, legumes, and canned goods tolerate sea freight well and have minimal transport emissions per serving.

FAQ
Is this food miles calculator free?
Yes, completely free with no signup required.
What are food miles?
Food miles measure the distance food travels from farm to plate. Imported strawberries in winter may travel 5,000+ miles by plane, while local summer strawberries travel under 100 miles. Higher food miles generally mean more transportation emissions, though the relationship isn't simple.
Are local foods always more eco-friendly?
Not always. The production method often matters more than transportation distance. For example, year-round local tomatoes grown in a heated greenhouse can have a higher carbon footprint than tomatoes grown outdoors and shipped from Spain. The type of food matters most — local beef still has far higher emissions than imported lentils.
What transport modes does the calculator cover?
Air freight (highest emissions, ~2 kg CO2/kg-km), sea freight (low, ~0.01 kg CO2/kg-km), road truck (medium, ~0.1 kg CO2/kg-km), rail (low, ~0.05 kg CO2/kg-km), and local delivery. The calculator selects likely transport modes based on origin distance and food type.
Does this support metric and imperial?
Yes. Enter weight in kg or lbs — toggle the unit system at the top of the calculator.
Do food miles really matter for the environment?
Food miles contribute roughly 6–10% of the total carbon footprint of the global food system. Transport emissions are smaller than production emissions (especially for meat and dairy), but they're a factor consumers can directly influence. Avoiding air-freighted perishables and choosing seasonal local produce for fresh fruits and vegetables can make a meaningful difference.
Is local food always better for the environment?
Not necessarily. While buying local reduces transport emissions, a food's total carbon footprint depends mainly on how it was produced. Locally raised beef still has a far higher carbon footprint than lentils imported from abroad. Heated greenhouses for out-of-season local produce can also have higher total emissions than the same food grown outdoors in the right climate and shipped by sea.
How do food miles compare to other carbon footprint factors?
For most foods, transportation represents only 10–20% of the total lifecycle carbon footprint. Production (farming, livestock, processing) typically accounts for 70–80%. This means what you eat has a bigger climate impact than where it comes from. However, the shipping method matters a lot — air freight is 210× more carbon-intensive than sea freight, so air-freighted exotics are a notable exception where food miles become significant.
How does the meal comparison mode work?
The Meal Comparison tab lets you build a complete meal from multiple ingredients to see the total food miles and CO₂. Choose from 5 pre-built templates (Summer BBQ, Thanksgiving Dinner, Weeknight Pasta, Taco Night, Sunday Roast) or add individual items from the Single Item tab. The seasonal panel shows in-season vs out-of-season CO₂ for common perishables like strawberries and asparagus.
Which foods have the highest food miles?
Air-freighted perishables top the list: cut flowers from Kenya (~5,800 miles by air), mangoes from Mexico/Brazil (~3,200 miles by air), asparagus from Peru (~3,400 miles by air), and out-of-season strawberries and blueberries from South America (~5,000+ miles by air). Among sea-freighted foods, palm oil from Indonesia/Malaysia (~10,000 miles), kiwi from New Zealand (~9,200 miles), and apples from New Zealand (~8,500 miles) log the most distance — but sea freight is so much cleaner that their total transport CO₂ is far below air-freighted foods.
