The Perils of Bottled Water

Phil Woolas again:

Phil Woolas, the environment minister, added that the amount of money spent on mineral water "borders on being morally unacceptable".

Their comments come as new research shows that drinking a bottle of water has the same impact on the environment as driving a car for a kilometre. Conservation groups and water providers have started a campaign against the £2 billion industry.

He says "up to 6 million bottles a day". Other estimates are of 2 billion bottles a year (roughly the same number).

Driving a car for a kilometre is, say, 130 g CO2? (Not entirely accuratebut it\’s a figure that bandied about).

2 billion x 130 g divided by 1 million to give us tonnage: 260,000 tonnes CO2. Hmm, about ten times what I\’d thought earlier.

My suspicion is that the linkage with driving a km has been rather sexed up. Still, of out 6 GT emissions as a country that is 0.004%.

How wonderful that we\’ve got the government concentrating on the important points, eh?

One comment on “The Perils of Bottled Water

  1. I’ve tried crunching some numbers on this but, for a start, it’s impossible to find figures for the carbon generated in the production & filling of that lightweight plastic bottle. It can’t be a great deal though. The best I can come up with for transporting the stuff by road is 0.025g/km of co² per litre. so you could certainly be shipping Evian for not much more than 28gCO²/litre. A tad more for Perrier. Maybe you get these figures if you’re airfreighting Antarctic meltwater.
    Actually, this reminds me of some Green on a radio program a couple of years back telling us about how many thousands of tons of CO² Londoners create by leaving their phone chargers plugged in. Actually, if you multiply the number of phones (presuming we’ve got at least one each, including the babeez, bless) times output of chargers (stamped on the bottom) times hours in a year & then folded the kW/hrs with the known generation costs the figures came out about right. The problem is that phone chargers, the ones that have been sold for the past ten years, don’t use anything like the stated consumption when not charging a phone. It’s minuscule. I got a multimeter & checked. So given that a phone takes about an hour to charge every 4 days, he was a couple of orders of magnitude out.
    I think they should stick to fairy tales.
