Recently Dave Burdick compared renewable energy to diet soda: You get all the fun without any of the guilt. Well, a randomly-associating commenter suddenly wondered about the effects of soda CO2 off-gassing on global warming.
Far be it from me to make light of a serious issue like global warming, but I really can't help but figure out the answer for myself.
So I found some quick (and occasionally disturbing) data:
- There's an average of 6 grams of CO2 in 1 liter of soda.
- The majority of CO2 used in the soft drink industry is a byproduct of, get this, petroleum refineries.
- There are 300 million people in America.
- And freakiest of all, the average American drinks 56 gallons of soda per year.
Anyhow...now for the math:
300 million people x 56 gallons per person x 3.78 liters per gallon x 6 grams of CO2 per liter soda / 1000 g per kg / 978 kg per ton = 389,570 tons of CO2 emitted by soft drinks yearly in America alone.
I'm sure someone will come along to check my math, but I'm fairly sure that's right.
Now, since most of this CO2 was going to be emitted from petroleum refineries anyway, it's not actually a CO2 emission. But it's pretty amazing that we, in effect, manage to sequester almost 400,000 tons of CO2 (the amount emitted by a town of around 45,000 people) in soda pop every year.
Now, if we could just keep buying them, and stop opening them.
Which brings up another point. Can a person go completely carbon neutral by purchasing soda and not opening it?
Average person produces 9 tons of CO2 per year. Average liter of Coke contains 6 g of CO2. Bulk 2 liter bottle of Coke 79 cents. That's all our data.
6 grams of CO2 per liter x 2 liters per bottle / 1000 g per kg / 978 kg per ton = 0.000012 tons of CO2 per bottle.
9 tons per person / 0.000012 tons per bottle x 0.79 dollars per bottle= $590,000 dollars per person per year to go carbon neutral by buying Coca Cola.
