Carbon footprint of carbonated beverage?

[friz]

Does any one know how much CO2 is released from a can of pop?

[bowtieguy]

'bout the same as a chimp passing gas.

Well the pressurised CO2 they put in the drinks is captured from the atmosphere, so it's carbon neutral, you only have to worry about packaging and production imprint. There appears to be no reason to assume that the carbon footprint of fizzy drinks is any worse than individually bottled fruit juices. Unless you go for "naturally sparkling" mineral waters, where deep underground they might have held their "fossil" carbon dioxide for quite a while, but now you're letting it out.

Actually the CO2 comes from carbonic acid, but I don't know where that comes from.

[GasSavers_RoadWarrior]

Solutions of CO2 in water are sometimes called "carbonic acid" because a very weak amount of that is formed. but that doesn't make them the same thing.

What about the greenhouse gases released from my shiny metal arse after I drink too many Diet Pepsis?

Don't forget the transportation of all the ingredients to the plant, the electricity used at the plant, for each of the ingredients to be made, the plastic bottles and their transportation, plastic pallets & labeling, transport from the plant to distribution centers, the footprint of the centers, transport from the centers to the stores, transport of the private vehicles to the store to get the soda, and all the downstream footprint of the waste products.

Then there are the vending machines...
