The data for aluminium, glass and PET containers is presented at the Coca-Cola website, which is presented as a link in the article above. You can use the data to construct a comparative carbon footprint for the different products.

Importantly, you should compare products with reference to a common “functional unit”. Let’s say the functional unit is the containment of 100ml of Classic Coca-Cola. On this basis, the amount of CO2 (grams) associated with the packaging for the containment of 100ml is:

aluminium (330ml) = 29
glass (330ml) = 75
PET (500ml) = 21
PET (2000ml) = 8

So, buying a 2 litre bottle of coke is almost 10 times better than buying 6 x 330ml glass bottles (1.98 liters) provided you can enjoy the whole bottle with friends before you lose the fizz.

Cheers!

Seems a bit daft not including PET bottles in this study
