‘ The Amazing Growth of the Christmas Tree’

‘ The Amazing Growth of the Christmas Tree’

Who would have imagined that one day the modest tree would be a huge global achievement? A couple of hundred years ago? Of course not Martin Luther, who is said to have decorated a tree with candles to celebrate the birth of Jesus Christ. Nor Prince Albert, who set up the first Christmas tree at Windsor Castle several centuries later. Who would have guessed that fir trees would be grown particularly for the export market in Denmark, that others would be transported in Oregon by helicopter, or that plastic replicas would be made by factories in China?

So, let’s get on the sleigh and take a ride around this seasonal product, so emblematic of market economic growth and world trade, for an informed choice between natural or artificial, regional or global manufactured goods.

Legend has it that on Christmas Eve Martin Luther was strolling in the rain, glimpsing stars twinkling among a fir tree branches. He cut off a sapling, took it home, candled it and told his son that it reminded him of how Christ appeared down from Heaven to live on Earth among mortals.

Many Protestant countries followed suit, and the evergreen holiday was first introduced in British homes in the nineteenth century when it became popular thanks to Queen Victoria’s Saxon husband, Prince Albert. Since then, the trees around which revellers danced in medieval town squares in Germany have been brought indoors

The Protestant origins of the decorated fir trees of Yuletide draw on other influences, as much as the invention of Father Christmas. A number of ancient figures and beliefs converged to form Santa Claus, long accepted by the Catholic Church, but not after some resistance.

For example, on December 23, 1951, in Dijon, France, a red-jacketed mannequin was burned outside the city’s cathedral on the grounds that Saint Nick was a pagan character that did not exist in real life. (This incendiary statement prompted anthropologist Claude Lévi-Strauss to pen  “The torture of Santa Claus”, a witty and thoughtful essay.)

Regardless of whether you see Christmas trees as a symbol of the winter solstice or the Nativity, the odds are good that you’ll be buying one this year. On Christmas night you will find them in  90% of UK homes, 77% of US households and nearly  25% of those in France  – they even have a measure of popularity in Australia, where Christmas occurs during the summer vacation.

Interestingly, most Christmas trees in Europe hail from the realm of Denmark. Why? Because the country grows them on a massive scale, making it the EU’s leading producer. But before going any further, we should explain that these trees are no longer harvested in forests but farmed. So fear not, you will do no damage to a real forest by purchasing a natural Christmas tree.

Indeed, it is precise because they no longer grow in forests that Christmas trees come from neither Norway nor Sweden, despite these countries’ abundant timber resources. Two figures may help clear things up: Denmark produces about 10 million Christmas trees a year, with the domestic market only absorbing 10%. The potential of farming first appeared in the 1990s when the country joined the European Union, with its system of farm subsidies.

Danish farmers were quick to adopt the Nordmann fir ( Abies nordmanniana ). While it was more expensive than the spruce ( Picea abies ) and doesn’t fill the room with a delicate smell of honey and resin, it sports bluish cones and long-lasting foliage with a silvery underside. Little seen in modern homes in the 1960s, the Nordmann has gradually taken over.

If you’re European and buy your tree at the Swedish retailer Ikea, the world’s biggest purchaser and seller of Christmas trees, it will be Danish. The company goes so far as to make them a loss leader: You will pay only 29 euros for the tree itself, along with baubles of various sizes and prices that you had absolutely no intention of buying but which will somehow land in your cart. You will receive a 20-euro voucher, to be spent on your next visit (before the end of February), but that will almost certainly be spent on another bunch of goodies of various sizes and prices…

The advantage with Ikea, though, is that it only sells one size of Christmas tree, 2 meters (roughly 6 feet) tall. So you don’t need to dither about getting a smaller, cheaper one, or a bigger, more expensive beast.

The theoretical relation between the size and price of a Christmas tree involves extremely complex equations. Was I to say that you should use a Hotelling-Faustmann type model you could scarcely be any the wiser, so perhaps I should offer some explanation. Harold Hotelling was a leading American economist and statistician, who established that the price of a natural resource should increase at the same pace as interest rates. The intuitive assumption is that the resource owner must choose between exploiting it today or tomorrow. If tomorrow’s price is lower than the amount they would earn from selling it today and putting the money in the bank, then they would obviously opt to sell it straight away. So the difference in price between a ten-year-old Nordmann fir, that stands 0.6 feet (20 cm) taller, and a nine-year-old tree depends on the rate of interest.

This is where Martin Faustmann, a German forester, comes in. He pointed out that trees can be replanted once they have been cut down, something that’s clearly not the case for coal or oil. If a farmer sells their firs after ten years rather than nine, they lose one year’s growth on the saplings they would have planted on the same plot of land. If this sparks your curiosity and you like equations, take a look at the article in the  American Journal of Agricultural Economics, “A Hotelling-Faustmann Explanation of the Structure of Christmas Tree Prices”. (US economists are marvellous because they publish papers on all sorts of subjects.)

It will come as no surprise that the United States both produces and consumes the most Christmas trees. For instance, the  Noble Mountain Tree Farm grows the Noble fir ( Abies Procera ), the Douglas fir ( Pseudotsuga menziesii ) and the Scots pine ( Pinus sylvestris ) on almost 2,000 hectares. Once felled, they are removed by helicopter, loaded onto trucks or refrigerated containers, and shipped to the rest of the United States, to Central America and even to places as far afield such as Doha, Singapore and Ho Chi Minh City.

On the other hand, you are less likely to know that Oregon-grown Christmas trees have become entangled in a trade dispute between the United States and Mexico. It started with a long argument about allowing  Mexican trucks onto US highways. Under the North American Free Trade Association, they were set to gain access to the road network in 2000.

For reasons that are more or less convincing (safety issues with vehicles, inexperienced truckers, trafficking of drugs and illegal immigrants, among others), the federal authorities dragged their feet and its trading partner finally lost patience. In 2009 the Mexican government imposed several billion dollars’ worths of import surtaxes on about 100 categories of goods, including Christmas trees. But why, you may wonder, did they bother with the little firs? It was all the fault of two Congressmen from Oregon. So there is a certain logic behind the targeting of retaliatory measures.

Christmas trees are also caught up in the trade war opposing the United States and China. To be exact, it has more to do with fairy lights and other seasonal decorations than it does with fir trees. The PRC does not grow them, nor does it celebrate Christmas. What’s more, the Chinese New Year is symbolized by an animal and the dominant colour is red, not green. (Next in line is the year of the rat, which starts on February 5.) But China does manufacture and export plastic Christmas trees and all the associated trimmings. Indeed, it is by far the world’s largest producer.

As soon as the conflict erupted, Washington slapped 10% extra duty on imports of Christmas decorations but did not touch PVC or polyurethane trees. Don’t ask me to explain this difference in treatment, as I haven’t a clue. Nor could I say why the surcharge on trimmings was lifted last summer. Perhaps Donald Trump was upset by the idea that kids at home would find their trees a little bare…

Of course, there is only the faintest connection between nursery tales and Chinese factories churning out Christmas decorations: no elves with pointed ears nor mischievous imps assisting Santa Claus. Rather, assembly-line workers and automated machines slicing PVC into countless synthetic pine needles. Manufacturing is not located somewhere north of the Polar Circle, but 300 kilometres southwest of Shanghai, in a city called Yiwu. Almost 1,000 firms making Christmas goods are based there. They account for 60% of global output of plastic fir trees and Christmas lights, gilded stars and those inevitable baubles. If you would like to see the fan belts and choppers of this workshop of the Nativity world in action, then watch the  National Geographic video, “I Did Not Know That: How Christmas Trees Are Made”. (It’s probably better to put the little ones to bed first, though.)

In the United States, the volume of fake Christmas tree sales is close to that of the real thing and rising steadily. Its attractive price – use it two years running and you start saving – is apparently not the reason for this trend. Indeed a dip in demand only marginally benefits their natural rival. Instead, their success in the United States seems a matter of convenience: no early-December shopping run, no needles to vacuum after the holidays.

In contrast, in France, the market share of artificial trees is pretty steady, stuck at about 20%. Which is just as well for local growers, as Danish and other imports only account for a fifth of overall volume. The French seem attached to their home-grown Christmas trees.

But which tree is “greener”, natural or artificial? At first glance a real tree seems a better bet: photosynthesis drives plant growth, capturing carbon dioxide. The synthetic alternative causes emissions, through oil extraction and PVC production, both of which consume large amounts of energy. But two key parameters may wipe out this advantage: the years the artificial tree is used and how far it is shipped (transportation also producing emissions).

The longer you keep your plastic tree, the less it will matter that it was made in China or that you bought it miles from your home. But the further your natural Christmas tree travelled, the worse its carbon budget will be. This ecological contest depends on other factors too, such as end-of-life processing (landfill or recycling) and environmental damage other than CO 2 emissions (in particular, the impact of pesticides and biodiversity). The results of the life-cycle analysis of the two commodities vary depending on the relevant parameters and values. For instance, the tipping point regarding re-use maybe  5 years or 20 years, depending on the sources. In short, it’s hard to tell.

For what it’s worth, I would advise you to opt for a natural fir tree, on the condition that you don’t just trash it, but take it to the nearest recycling centre. If in doubt, get a locally-sourced tree or better yet, an organic one.

Whatever happens, don’t make the same mistake as the envious little tree in the  Hans-Christian Andersen story, unable to appreciate living in the present.

“Out in the woods stood a nice little Fir Tree. The place he had was a very good one: the sun shone on him: as to fresh air, there was enough of that, and round him grew many large-sized comrades, pines as well as firs. But the little Fir wanted so very much to be a grown-up tree…”

And with this thought, we wish you a very happy Christmas, with or without a tree decked with Chinese-made decorations.
