Eating local or not?

Is eating locally really that important? Many people suggest that eating local can help reduce your carbon footprint, but recent data suggests that while it may have some benefits, it might not be as impactful on sustainability as we originally thought.

In fact, what you choose to eat is more significant than where it comes from. Transportation only accounts for a small portion of a food’s greenhouse gas emissions, with other factors like production and processing playing a much larger role. So, opting for lower emission foods like poultry rather than high emission options like beef can make a bigger difference in reducing your carbon footprint, regardless of their origin.

With regards to reducing your carbon footprint, eating local can be particularly effective for highly perishable foods that require speedy transportation due to their short shelf lives.

These foods are often air-freighted, resulting in emissions that are up to 50 times greater than transportation by sea. Examples of these foods include fresh fruits and vegetables such as asparagus, green beans, berries, and pineapples.

It’s worth noting that only a small proportion of the food supply is transported by air – the majority is transported by large ships or trucks. In addition to this environmental benefit, eating local can also support local producers who use sustainable farming practices, allow you to eat seasonally, and provide you with a clear understanding of where your food comes from.

Consume red meat in moderation

Approximately 83% of our dietary emissions come from protein-rich foods, including meats, dairy, and eggs. When considering the overall carbon footprint, beef and lamb have the highest impact due to their extensive land use, feeding requirements, processing, and packaging. Additionally, cows produce methane during the digestion process, which further contributes to their carbon footprint.

While red meats produce about 60 kg of CO2 equivalents per kg of meat (a common measure of greenhouse gas emissions), other protein sources have significantly lower emissions. For example, poultry farming produces 6 kg, fish 5 kg, and eggs 4.5 kg of CO2 equivalents per kg of meat.

Reducing your intake of red meat can greatly reduce your carbon footprint. While purchasing grass-fed red meat from local sustainable sources may lead to a slight decrease in greenhouse gas emissions, the evidence suggests that reducing overall red meat consumption has a greater impact.

Eat more plant-based food

To promote ethical omnivorism, consider incorporating more plant-based protein sources into your diet. Options such as tofu, beans, peas, quinoa, hemp seeds, and nuts have a lower carbon footprint than most animal proteins.

While the nutritional content may vary compared to animal proteins, appropriate portion sizes can provide adequate protein. Remember, adding plant-based protein sources does not require eliminating animal foods entirely. A simple way to reduce animal protein intake is by substituting half of the protein in a recipe with a plant-based option.

Reduce food waste

It is important to note that globally, food waste contributes to 6% of greenhouse gas production. Although this includes losses throughout the supply chain due to inadequate storage and handling, a significant portion of this waste comes from retailers and consumers discarding food.

To combat this issue, there are several practical ways you can reduce food waste. One approach is to purchase frozen fruits and vegetables if you do not plan on consuming them within the next few days.

Additionally, vacuum-sealed frozen fish is an excellent option due to its short shelf life compared to other meats. Another way to reduce food waste is by utilizing all edible parts of fruits and vegetables, such as the stems of broccoli. If your local supermarket has a rejected produce bin, consider shopping there. Lastly, avoid buying more food than you need for a given time period.

In addition to its positive impact on the environment, cutting down on food waste can also lead to significant savings on your grocery bill. We recommend giving some of the techniques outlined above a try as a first step towards reducing both your food waste and carbon footprint.

As summary, the production of food contributes significantly to worldwide emissions by utilizing land, emitting greenhouse gases, consuming water, and causing fertilizer runoff. Although it cannot be completely avoided, adopting ethical eating habits can significantly decrease your carbon footprint. This can be achieved by reducing red meat consumption, incorporating more plant-based proteins into your diet, and minimizing food waste. By being mindful of your food choices, you can contribute towards creating a sustainable food environment for future generations.
