Leo Hickman, a Guardian columnist, published an interesting book called “Final Call - In search of the True Cost of our Holidays”. Its reviewed here and I’ve made a few comments on it.

Eco tourism is all the rage these days and rightly so. We should always consider the impact of where we go and what we do. But as consumers of goods, services and exotic holidays we expect the price to reflect the cost of what we are paying for. If it doesn’t is that our fault or problem?

Well that’s where the consideration or “ethics” of your decision comes into play. I’m in favour of travel as it expands the mind. body and soul. It allows us to gain a different and newer perspective on the world. But do we dare look beneath the surface as Leo has done?

I’m reminded of the excellent Stephen Frears film “Dirty Pretty Things” about the  immigrant workers who keep London going at night whilst people sleep easy. Crap working conditions for service staff are nothing new so why should it be any different on holiday?

What should happen is that people get paid proper wages and work in decent conditions. Then it’s up to them whether to take a job or not. Madeleine Bunting deals with this issue quite well in her book “Willing Slaves” which also looks at the guest worker phenomenon.

My interest is more in the environmental sphere. Simply put we should be paying the Trucost of our activities. How we get that is a bit trickier but doable.  I’ve looked at this before and having been to the UK recently its clear that this issue is center stage.

We must move quickly to connect external environmental costs with the pricing mechanism. Once a cost has been calculated (carbon, nitrogen runoff, water) then that cost gets added in at the point of extraction, abstraction or manufacture. The EC (external cost) flows back to an Environmental Contingency Fund where it sits (in sovereign bonds) until it can be put towards paying for the exact cost that was incurred, whether that is planting some forests to sequester carbon, cleaning a river or fencing land or implementing new water management processes.

As much as we would like it to be, it isn’t (as yet) an exact science. But it will alert consumers to the true cost of the good and allow them to make more accurate purchasing decisions.

Then maybe we can actually enjoy our holiday instead of worrying about how much damage we’re doing to “the planet”.

Barely a week passes without a new campaign in the UK around the issue of food miles and NZ produce. Though this has been thoroughly debunked by the report from Lincoln University the story continues to rumble along.

This is just the beginning of a more serious debate on the issue of environmental costs otherwise known as externalities. Food miles is just a simple way of engaging the public and media just as the phrase “think global, buy local” has always done.

We all like to support our local farmers whether in NZ, UK, France, Japan or the US. However we all like to sell as much as our produce into markets where we can achieve a better price (even after taking account of transport costs). NZ is heavily geared towards exporting and with a large productive base and small local market it is more exposed than many other larger countries.

Stepping away from the hype and hysteria we can see that the Food Miles debate is both important and necessary. Consumers should be paying the full price for the goods they buy and that includes the basic inputs of energy and matter as well as ecosystem goods and services.

Whilst food miles comes across as a marketing ploy and is somewhat simplistic in its formulation, it can be seen as the start of a serious attempt to bring Trucost pricing into the mainstream economic system. Of course it makes sense to buy your veggies from the farmer down the road but the supermarket system is all pervasive and has driven costs down so far that they have been able to get away with an international supply chain as well as shipping domestic produce many miles further than necessary.

Pricing ecosystem services in at the primary level would see a vastly different pricing mechanism: one which included the price of nutrient and effluent run off, mining run off, soil depletion, air quality processing, clean water provision and the numerous other services which have enormous economic value.

If this happens then maybe we can relax a bit as the produce in our supermarkets and farmers markets will be priced on the same basis.

Only then will we really know which is really cheaper.
