Where does the CO2 in carbonated beverages come from currently? Is it something produced which would now be displaced resulting in a net reduction? If we're producing CO2 as the product, we could lower that amount by recycling already produced CO2.
- aetherson 12y agoNo idea at all. But even if it is, this is more in the line of mitigating current CO2 increases than "taking CO2 out of the atmosphere." And if you grow the market for carbonated beverages by having cheaper CO2, that market growth will be CO2-positive, not CO2-reducing.
- yongjik 12y agoCarbonated beverages are a red herring. This page[1] says a can of soda has 2.2g of CO2. If every single person in the world (population 7.125B) drinks 10 cans of coke every day for a year, we will be using 63 Mt of CO2. Mankind emitted 33615 Mt of CO2 in 2010[2].

(Edit: sorry I at first miscalculated the result to be 6.3 Mt.)
- LanceH 12y agoI only intended to point out it is possible to reduce CO2 emissions by recycling it, even it the end product releases the same amount of CO2. I don't know that we produce CO2 for CO2, or where the numbers lie. Just that the prior post said it gets released anyway, so how can it be an improvement?
- mikeyouse 12y agoMost of the commercial CO2 in the US is captured from natural gas 'sweetening' or from fertilizer production. It's transported from the plants/refineries in a rather substantial pipeline network mostly in the South. Companies like Air Products and Praxair typically buy CO2 off of these pipelines and then clean it up to whatever specification is required (Industrial, Food & Beverage, Pharmaceutical, etc) then sell it to the end users. I wouldn't be surprised if the major beverage companies had their own connections to the pipeline and did their own processing, but they're only a small portion of the commercial CO2 market.
