Pablo Päster, who is a sustainable engineer, has done a thorough and exhaustive study and has worked out the true cost of producing and transporting the water. What's probably the most surprising is that it takes a staggering 26 times more water to make the bottle than it actually holds.
Treehugger has summarised the findings:-
the manufacture and transport of that one kilogram bottle of Fiji water consumed 26.88 kilograms of water (7.1 gallons) .849 Kilograms of fossil fuel (one litre or .26 gal) and emitted 562 grams of Greenhouse Gases (1.2 pounds).
In a nut shell this whole article is complete "bunk" because no actual research was done. Only assumptions.
I still agree that it's not very cost effective (especially when you filter your own water like Chad).
I just question the factors behind the numbers and how unbiased the science can be coming from a website called "treehugger" can really be.
