Local Food vs Food Miles: Is Local Better for Environment 2026

Local food is often touted as better for the environment, but the concept of food miles—the distance between farm, factory, and plate—gained prominence in the early 2000s. The idea was simple: longer, more complex supply chains caused higher emissions than food sourced closer to home. But in today's context, with growing concerns about climate change and supply chain resilience, does buying local still make environmental sense? We delve into the nuances of food miles, the Australian food system, and what truly matters for sustainable eating.

The Rise and Relevance of Food Miles

Food miles measure the distance food travels from production to consumption. In the early 2000s, this metric became a popular way to gauge the environmental impact of our diets. The logic seemed sound: transporting food over long distances requires energy, primarily fossil fuels, contributing to greenhouse gas emissions. However, the relationship between food miles and environmental impact is more complex than it appears.

Dr Kimberley Reis, who researches regional and local food resilience at Griffith University, notes that supply chains in Australia are largely shaped by the grocery sector. Food can travel vast distances across the country—and beyond—to reach supermarket outlets, with freight costs passed on to consumers. But recent global events, such as the war in the Middle East, have refocused attention on the role of transport and the importance of self-sufficiency, including the threat of rising food prices due to diesel price spikes. This raises the question: do food miles still matter?

Environmental Impact of the Food System

According to Assoc Prof Mengyu Li at the University of Sydney, almost a third of global greenhouse gas emissions are connected to the food system through land clearing, raising animals, growing crops, processing and packaging, transport, and waste. "We cannot meet our climate goals if we don’t do anything about [the] food system," she says. This means that while transport is a factor, it's just one piece of the puzzle.

In fact, the emissions from food production often dwarf those from transportation. For example, producing beef generates significantly more greenhouse gases than growing vegetables, regardless of how far they travel. Therefore, focusing solely on food miles can be misleading.

Comparing Emissions: Local vs. Imported

Let's compare the carbon footprint of some common foods based on production and transport. The table below illustrates the greenhouse gas emissions per kilogram of food, highlighting the dominance of production methods over distance.

As the table shows, for most foods, production emissions are much higher than transport emissions. However, for air-freighted perishables like tomatoes, transport can significantly increase the total footprint. So, while local food can reduce transport emissions, the type of food we eat matters more.

Key Takeaways for Sustainable Eating

• Prioritize plant-based foods: Reducing meat and dairy consumption has a bigger impact than buying local.
• Choose seasonal and local when possible: This reduces transport emissions and supports local economies.
• Minimize food waste: Wasted food accounts for a significant portion of emissions.
• Consider the full lifecycle: Look beyond food miles to production methods, packaging, and processing.
• Support sustainable farming: Regenerative agriculture can sequester carbon and improve soil health.

The Australian Context: Supply Chains and Resilience

Australia's food supply chains are heavily influenced by major supermarkets, which often prioritize efficiency and cost over local sourcing. This can lead to food traveling thousands of kilometers from farm to store. However, there is a growing movement towards local food systems, farmers' markets, and community-supported agriculture, which can enhance resilience and reduce environmental impact.

Dr Reis emphasizes that building local food resilience is crucial for withstanding global shocks, such as fuel price spikes or geopolitical conflicts. By diversifying our food sources and supporting local producers, we can create a more sustainable and secure food system.
