2. The History and Evolution of the Food Miles Concept
The term “food miles” emerged in the early 1990s, coined by Professor Tim Lang at the City University in London. It was initially conceived as a tool to raise awareness about the environmental consequences of transporting food over long distances. The concept quickly gained momentum, resonating with consumers concerned about the growing carbon footprint of the global food system.
In its early days, the food miles concept focused primarily on the distance food traveled as a simple metric for assessing environmental impact. However, as research evolved, it became clear that distance alone wasn’t a comprehensive measure. Factors such as the mode of transportation, production methods, and the overall lifecycle of the food product also play significant roles in determining its environmental footprint.
Over time, the food miles concept has expanded to encompass a more holistic approach to evaluating the environmental impact of food. This includes considering factors such as:
- Transportation methods: The mode of transportation used to move food (e.g., air, sea, road, rail) has a significant impact on emissions.
- Production practices: Sustainable farming practices, such as organic farming and reduced pesticide use, can help minimize the environmental impact of food production.
- Packaging: The type and amount of packaging used for food can contribute to its overall environmental footprint.
- Waste: Food waste at various stages of the supply chain, from production to consumption, can have a significant environmental impact.
Today, the food miles concept serves as a valuable starting point for consumers seeking to make more sustainable food choices. While it’s not a perfect metric, it raises awareness about the environmental consequences of food transportation and encourages consumers to consider the origin of their food and its impact on the planet.
3. Calculating Food Miles: Methods and Considerations
Calculating food miles can be a complex undertaking, as it involves tracking the journey of food from its source to the consumer’s plate. Several methods have been developed to estimate food miles, each with its own strengths and limitations.
3.1. Simple Distance Calculation:
The simplest method involves measuring the straight-line distance between the point of origin and the point of consumption. This approach provides a basic estimate of food miles but doesn’t account for the actual route taken or the mode of transportation used.
3.2. Weighted Average Source Distance (WASD):
Developed by Annika Carlsson-Kanyama, the WASD formula takes into account the weight of the transported food and the distance it travels from the place of production to the place of sale. This method provides a more accurate estimate of food miles compared to the simple distance calculation.
3.3. Weighted Total Source Distance (WTSD):
The Leopold Center for Sustainable Agriculture developed the WTSD formula for analyzing foods with multiple ingredients. It calculates the weight and distance traveled of each individual ingredient to provide a comprehensive estimate of food miles for processed foods.
3.4. Weighted Average Emissions Ratio (WAER):
Developed by the nonprofit LifeCycles, the WAER formula considers the greenhouse gas emissions associated with each mode of transportation employed. This method provides the most accurate assessment of the environmental impact of food transportation.
3.5. Considerations When Calculating Food Miles:
When calculating food miles, it’s important to consider the following factors:
- Mode of transportation: Different modes of transportation have varying levels of fuel efficiency and emissions.
- Route taken: The actual route taken by the food may be longer than the straight-line distance between the origin and destination.
- Type of food: Perishable foods may require faster transportation, which can increase food miles and emissions.
- Packaging: The type and amount of packaging used can affect the weight and volume of the food, influencing transportation costs and emissions.
