Interpreting the Results
The number of "food miles" is a simplified but powerful indicator of the environmental impact associated with the transportation of your food.
| Metric | What It Represents |
|---|---|
| Distance Traveled | The direct distance (in kilometers or miles) that the food has traveled. This figure is an approximation of the minimum distance between the two selected points. |
| Approximate CO₂ Emissions | An estimate of the carbon dioxide emissions generated by the transportation of a product. This number depends heavily on the mode of transport (air, sea, land). |
Food Miles: The Unseen Journey on Your Plate
We often think of food as something that appears magically on supermarket shelves. However, each ingredient has a long journey from its field or farm to our homes. The concept of food miles measures this journey, quantifying the distance between the producer and the final consumer. This indicator, while not the only measure of a food's carbon footprint, is a powerful reminder of how globalized our food system is and the environmental costs associated with it.
The transportation of food, especially by air, is a significant source of **greenhouse gas (GHG) emissions**, which contribute to climate change. A study published in the journal *Science* estimated that food transport is responsible for about 3% of global GHG emissions. By choosing to consume local and seasonal products, we can significantly reduce this impact, not only by reducing the distance but also by supporting agricultural practices that are often more sustainable and respectful of the land.
How are "Food Miles" Calculated?
The calculation of food miles is based on the great-circle distance (the shortest distance between two points on a sphere) between the origin and destination points. While this is a simplification that does not consider the complexity of real logistics routes, it serves as a useful and practical indicator for comparing the impact of different products. It helps us visualize the "cost" of having a strawberry in winter or a mango thousands of kilometers from where it was grown.
Beyond Transport: The Total Footprint of Food
It is important to remember that food miles are only one piece of the puzzle. The **total environmental footprint** of a food includes other factors that are often more significant than transport. The production method, for example, is the largest source of emissions for most products. For example, producing one kilogram of beef generates a much higher carbon footprint than producing a kilogram of legumes, even if the beef is local and the legumes are imported.
Therefore, a truly sustainable diet combines several principles:
- Prioritize local and seasonal: Reduces the impact of transport and supports the local economy.
- Reduce consumption of high-impact foods: Focus on reducing meat and dairy consumption.
- Minimize waste: Food waste in landfills produces methane, a potent greenhouse gas.
"Every time you spend money, you're casting a vote for the kind of world you want." - Anna Lappé
This famous quote is especially relevant for our food choices. By choosing foods with fewer miles, we are voting for a more local, conscious, and environmentally friendly food system. This tool is a simple but powerful way to make that vote a tangible part of our daily lives.

Frequently Asked Questions about Food Miles
Food miles refer to the distance food travels from where it is grown or produced to where it is consumed. The term is used as a measure of the environmental impact of a food product.
While the calculator only measures distance, the mode of transport is a crucial factor in the real impact. Transport by air has a much higher carbon footprint per kilometer than transport by sea or land.
No. While it is a good indicator, a local food grown in a heated greenhouse or with a high use of fertilizers may have a greater impact than a food imported from a country with more efficient farming conditions.
You can reduce your food miles by buying from local farmers' markets, subscribing to a Community Supported Agriculture (CSA) box, or choosing products that are in season in your region. Consider growing your own food as well.
