NZ Olive Oil Makes Unwanted Food Miles List
When a boutique New Zealand olive oil was branded an ‘eco-crime’ for the distance it travelled to Britain, it lit up a genuine debate. Food miles feel intuitive, but they are a crude proxy — and olive oil is a good example of why the whole story matters more than the map.
A boutique New Zealand olive oil once found itself on a British newspaper’s list of ‘food-mile eco-crimes’ — singled out, like New Zealand kiwifruit before it, for the fuel supposedly burned getting it halfway round the world. The producer’s reply was pointed: the oil travels by ship, not plane, its growing is environmentally sound, and the whole exercise smelled of European markets protecting themselves under a green banner. That row, years old now, is still one of the clearest ways to understand why ‘food miles’ can mislead.
Why distance is a crude measure
Food miles count how far a food travelled, and stop there. But distance is only one input into a food’s carbon footprint, and often a small one. How the food was grown, how it was packaged, how it was stored, and above all how it was transported usually matter far more. A tomato grown in a heated glasshouse next door can carry a heavier footprint than one shipped from a sunny field a continent away. Distance is easy to print on a label; it is a poor summary of the truth.
Sea versus air — the decisive difference
The single biggest thing food miles hide is the mode of transport. Moving goods by sea is remarkably efficient per litre — a bottle of oil shares a vast container ship with millions of others, so its individual share of the fuel is tiny. Air freight is the opposite: energy-hungry and dramatically higher per kilo. An oil shipped by sea from the far side of the planet can easily have a smaller transport footprint than one flown a shorter distance. Lumping the two together under ‘miles’ is precisely the error.
What a thoughtful buyer does
Buying local is often a fine instinct — fresher food, money kept in the community, support for nearby growers. But do not mistake a food-miles headline for a full environmental audit, and be alert to protectionism dressed as ecology. For olive oil specifically, the things that genuinely reduce waste and footprint are buying oil you will actually finish before it goes rancid, choosing sea-freighted over air-freighted where you can tell, and valuing how it was grown over how far it came.
| Factor | What it really tells you | Weight |
|---|---|---|
| Distance (food miles) | How far it travelled — only one input | Often small |
| Transport mode | Sea vs air — the decisive factor | Large |
| Growing method | Field vs heated glasshouse, water use | Large |
| Packaging & waste | Glass, spoilage, oil you never finish | Real |
Reading a food-miles claim
- Distance is one input, not the whole footprint.
- Sea freight is highly efficient per litre; air freight is the culprit.
- How a food is grown and packaged often outweighs how far it came.
- Watch for protectionism wearing a green badge.
- For oil, the biggest waste is a bottle you never finish — buy a size you will use.
Food miles and olive oil: common questions
What are food miles?
A measure of how far a food travelled from where it was produced to where it is sold — intuitive, but only one part of its environmental footprint.
Is distance a good measure of footprint?
Not on its own. Growing method, packaging, storage and especially transport mode usually matter more than raw distance.
Why does sea freight change the picture?
Shipping by sea is extremely efficient per litre, so a bottle sent by sea from far away can have a smaller transport footprint than one flown a shorter distance.
Was the New Zealand oil really an eco-crime?
The producer argued not — it travelled by ship, was soundly grown, and the label looked like market protectionism dressed as ecology.
What reduces olive oil’s footprint most?
Buying a size you will finish before it turns, favouring sea over air freight where you can tell, and valuing how it was grown over how far it came.
The food-miles headline is a tidy story that usually hides the real one. Distance is one small input; how a food was grown, packaged and above all transported matters far more — and a bottle shipped by sea from the far side of the world can beat one flown a shorter hop. Be a little wary when a ‘green’ scolding conveniently protects the local market. For oil, your biggest waste is the bottle you let go rancid, so buy a size you’ll actually finish.
