Cod caught off Norway is shipped to China to be turned into filets, then shipped back to Norway for sale. Argentine lemons fill supermarket shelves on the Citrus Coast of Spain as local lemons rot on the ground. Half of Europe’s peas are grown and packaged in Kenya.
In the US, FreshDirect proclaims kiwi season has expanded to “All year!” now that Italy has become the world’s leading supplier of New Zealand’s national fruit, taking over in the Southern Hemisphere’s winter.
Food has moved around the world since Europeans brought tea from China, but never at the speed or in the amounts it has over the last few years. Consumers in not only the richest nations but, increasingly, the developing world expect food whenever they crave it, with no concession to season or geography.
Increasingly efficient global transport networks make it practical to bring food before it spoils from distant places where labor costs are lower. And the penetration of mega-markets in nations from China to Mexico with supply and distribution chains that gird the globe — like Wal-Mart, Carrefour and Tesco — has accelerated the trend.
But the movable feast comes at a cost: pollution — especially carbon dioxide, the main global warming gas — from transporting the food.
Under long-standing trade agreements, fuel for international freight carried by sea and air is not taxed. Now, many economists, environmental advocates and politicians say it is time to make shippers and shoppers pay for the pollution, through taxes or other measures.
“We’re shifting goods around the world in a way that looks really bizarre,” said Paul Watkiss, an Oxford University economist who wrote a recent EU report on food imports.
He said that Britain, for example, imports — and exports — almost 14,000 tonnes of waffles a year, and similarly exchanges 18 tonnes of bottled water with Australia. More important, Watkiss said, “we are not paying the environmental cost of all that travel.”
Europe is poised to change that. This year the European Commission in Brussels announced that all freight-carrying flights into and out of the EU would be included in the trading bloc’s emissions-trading program by 2012, meaning permits will have to be purchased for the pollution they generate.
The commission is negotiating with the global shipping organization, the International Maritime Organization, over various alternatives to reduce greenhouse gases. If there is no solution by year’s end, sea freight will also be included in Europe’s emissions-trading program, said Barbara Helferrich, a spokeswoman for the European Commission’s Environment Directorate.
“We’re really ready to have everyone reduce — or pay in some way,” she said.
The EU, the world’s leading food importer, has increased imports 20 percent in the last five years. The value of fresh fruit and vegetables imported by the US, in second place, nearly doubled from 2000 to 2006.
Under a little-known international treaty called the Convention on International Civil Aviation, signed in Chicago in 1944 to help the fledgling airline industry, fuel for international travel and transport of goods, including food, is exempt from taxes, unlike trucks, cars and buses. There is also no tax on fuel used by ocean freighters.
Proponents say ending these breaks could help ensure that producers and consumers pay the environmental cost of increasingly well-traveled food.
The food and transport industries say the issue is more complicated. The debate has put some companies on the defensive, including Tesco, Britain’s largest supermarket chain, known as a vocal promoter of green initiatives.
Some of those companies say that they are working to limit greenhouse gases produced by their businesses but that the question is how to do it. They oppose regulation and new taxes and, partly in an effort to head them off, are advocating consumer education instead.
Tesco, for instance, is introducing a labeling system that will let consumers assess a product’s carbon footprint.
Some foods that travel long distances may actually have an environmental advantage over local products, like flowers grown in the tropics instead of in energy-hungry European greenhouses.
“This may be as radical for environmental consuming as putting a calorie count on the side of packages to help people who want to lose weight,” said Trevor Datson, a spokesman for Tesco.
Better transportation networks have sharply reduced the time required to ship food abroad. For instance, improved roads in Africa have helped cut the time it takes for goods to go from farms on that continent to stores in Europe to four days, compared with 10 days not too many years ago.
And with far cheaper labor costs in African nations, Morocco and Egypt have displaced Spain in just a few seasons as important suppliers of tomatoes and salad greens to central Europe.
“If there’s an opportunity for cheaper production in terms of logistics or supply it will be taken,” said Ed Moorehouse, a consultant to the food industry in London, adding that some of these shifts also create valuable jobs in the developing world.
The economics are compelling. For example, Norwegian cod costs US$1.36 per pound (US$3 per kilogram) to process in Europe, but only US$0.23 per pound to process in Asia.
The ability to transport food cheaply has given rise to new and booming businesses.
“In the past few years there have been new plantations all over the center of Italy,” said Antonio Baglioni, export manager of Apofruit, one of Italy’s largest kiwi exporters.
Kiwis from Sanifrutta, another Italian exporter, travel by sea in refrigerated containers: 18 days to the US, 28 to South Africa and more than a month to reach New Zealand.
Some studies have calculated that as little as 3 percent of emissions from the food sector are caused by transportation. But Watkiss said the percentage was growing rapidly. Moreover, imported foods generate more emissions than generally acknowledged because they require layers of packaging and, in the case of perishable food, refrigeration.
Britain, with its short growing season and powerful supermarket chains, imports 95 percent of its fruit and more than half of its vegetables. Food accounts for 25 percent of truck shipments in Britain, according to the British environmental agency, DEFRA.
Datson acknowledged that there were environmental consequences to the increased distances food travels, but he said his company was merely responding to consumer appetites.
“The offer and range has been growing because our customers want things like snap peas year round,” Datson said. “We don’t see our job as consumer choice editing.”
Global supermarket chains like Tesco and Carrefour, spreading throughout Eastern Europe and Asia, cater to a market for convenience foods, like washed lettuce and cut vegetables. They also help expand the reach of global brands.
“Food is traveling because transport has become so cheap in a world of globalization,” said Frederic Hague, head of Norway’s environmental group Bellona. “If it was just a matter of processing fish cheaper in China, I’d be happy with it traveling there. The problem is pollution.”
The EU has led the world in proposals to incorporate environmental costs into the price consumers pay for food at the market.
Switzerland, which does not belong to the EU, already taxes trucks that cross its borders.
In addition to bringing airlines under its emission-trading program, Brussels is also considering a freight charge specifically tied to the environmental toll from food shipping to shift the current calculus that “transporting freight is cheaper than producing goods locally,” the commission said.
The problem is measuring those emissions. The fact that food travels farther does not necessarily mean more energy is used. Some studies have shown that shipping fresh apples, onions and lamb from New Zealand might produce lower emissions than producing the goods in Europe, where — for example — storing apples for months would require refrigeration.
Shippers have vigorously fought the idea of levying a transportation fuel tax, noting that if some countries repealed those provisions of the Chicago Convention, it would wreak havoc with global trade, creating an uneven patchwork of fuel taxes. It would also give countries that kept the exemption a huge trade advantage.
Some European retailers hope voluntary green measures like Tesco’s labeling — set to begin later this year — will slow the momentum for new taxes and regulations. Customers may be surprised by what they discover.
Box Fresh Organics, a popular British brand, advertises that 85 percent of its vegetables come from the British midlands. But in winter, in its standard basket, only the potatoes and carrots are grown in Britain. The grapes are from South Africa, the fennel is from Spain and the squash is from Italy.
Today’s retailers could not survive if they failed to offer such variety, Moorehouse said.
“Unfortunately,” he said, “we’ve educated our customers to expect cheap food, that they can go to the market to get whatever they want, whenever they want it. All year. 24/7.”

Trying to force a partnership between Taiwan Semiconductor Manufacturing Co (TSMC) and Intel Corp would be a wildly complex ordeal. Already, the reported request from the Trump administration for TSMC to take a controlling stake in Intel’s US factories is facing valid questions about feasibility from all sides. Washington would likely not support a foreign company operating Intel’s domestic factories, Reuters reported — just look at how that is going over in the steel sector. Meanwhile, many in Taiwan are concerned about the company being forced to transfer its bleeding-edge tech capabilities and give up its strategic advantage. This is especially
US President Donald Trump’s second administration has gotten off to a fast start with a blizzard of initiatives focused on domestic commitments made during his campaign. His tariff-based approach to re-ordering global trade in a manner more favorable to the United States appears to be in its infancy, but the significant scale and scope are undeniable. That said, while China looms largest on the list of national security challenges, to date we have heard little from the administration, bar the 10 percent tariffs directed at China, on specific priorities vis-a-vis China. The Congressional hearings for President Trump’s cabinet have, so far,
US political scientist Francis Fukuyama, during an interview with the UK’s Times Radio, reacted to US President Donald Trump’s overturning of decades of US foreign policy by saying that “the chance for serious instability is very great.” That is something of an understatement. Fukuyama said that Trump’s apparent moves to expand US territory and that he “seems to be actively siding with” authoritarian states is concerning, not just for Europe, but also for Taiwan. He said that “if I were China I would see this as a golden opportunity” to annex Taiwan, and that every European country needs to think
For years, the use of insecure smart home appliances and other Internet-connected devices has resulted in personal data leaks. Many smart devices require users’ location, contact details or access to cameras and microphones to set up, which expose people’s personal information, but are unnecessary to use the product. As a result, data breaches and security incidents continue to emerge worldwide through smartphone apps, smart speakers, TVs, air fryers and robot vacuums. Last week, another major data breach was added to the list: Mars Hydro, a Chinese company that makes Internet of Things (IoT) devices such as LED grow lights and the
