Chocolate Made in South Africa for homesick Brits?


This blog is about the weirdness of global trade… and the
lengths (literally) we go for chocolate.

The wrapper on my Marks & Spencer (M&S) valentine chocolates read: “Made with our exclusive British Milk chocolate recipe, Made in
South Africa”.

Incredibly, it seemed that a firm in South Africa (SA) was targeting local people with a taste for British chocolate, and somehow M&S
sourced them for sale in the UK! 

Was this I wondered another example of fuel miles not being
built into food production costs (see “food miles”), like apples  from the Cape or Kenyan flowers at petrol stations?

Is local food environmentally costly?

Many consumers feel that they should be buying “local food” to help combat climate change – but could “local food” actually result in more carbon emissions than food distributed through conventional supply chains? David Oglethorpe raises this possibility along with some other surprising ideas in a paper in CAB Reviews.


Oglethorpe, of the Newcastle Business School, Northumbria University points out that the economies of scale of major production networks do actually result in some environmental benefits. A study of sausages showed that using HGVs in efficient distribution chains resulted in a much lower carbon footprint per sausage than resulted from the many smaller journeys in smaller vehicles that were typical of local food production.

In attempting to be more “green”, many consumers feel that they should not buy food that is highly packaged. But Oglethorpe says that there is much higher food waste with food that is low on packaging. And the emissions associated with food decay, particularly methane, are much more significant than for packaging materials. So it might make more environmental sense to use more packaging. 

Some producers who supply local food also use more environmentally friendly farming or production techniques. However, this is not always the case, and studies suggest that while the association may be strong in the consumer’s mind, in reality it may be weak. There are also examples where local production is more resource-consuming than production in a geographical area more suited to a particular type of farming.  For example, there is some evidence that New Zealand lamb imported to the UK has a smaller environmental impact than that produced in the UK, despite the obvious transport-related emissions.

However, local food may have other benefits. It can provide an important boost to the local economy, offering employment, and attracting tourism, local festivals and the “vibrancy” of an area. The fact that consumers can meet face-to-face with producers may have positive effects on the local community. Some local foods are of better quality – e.g. “local” meat products tend to have higher meat content than typical mass distribution equivalents. However, some that target an “indulgent” consumer have high sugar or fat content, and thus could have negative health impacts.


So consumers should not be assumers that local is always best. However, there is currently no agreement on what “local” means, and the hidden environmental costs are far from obvious. As with many environmental analysis, research is only beginning to scratch the surface, and agreeing what is fair to count within the cost is a controversial business.

Easier being green…

Last Saturday, I cycled to Tesco’s*. It’s around five miles away from where I
live, so wasn’t a huge effort and, to be fair, I could use the extra exercise. I
stress this because I’m about to mention the environment. Before you head off to
the ‘post comment’ box below, I must stress that my environmental credentials
aren’t great. Like many of us, I guess I do my bit, but sometimes find this
relationship a bit one sided. My meagre efforts at saving it are simply not
appreciated. It must be that unconditional love that only a parent could show a
tempestuous child. As if to prove my point, as I headed out of Tesco’s with a
re-usable bag of groceries on my back, it rained. It seems to do this most times
I ‘do my bit for the environment’ and leave the car at home.

The environment clearly doesn’t appreciate my efforts.
