At least for milk this was AFAIK analyzed and found to be wrong, i.e. the transport and washing of glass bottles has a higher impact on the environment then single use tetra-packs or those thin-walled plastic bags that are less commonly used.
Of course these cardboard containers are not suitable for carbonated beverages and I suspect the calculation is somewhat different for the stronger type of plastic or metal containers necessary for that.
However I personally see little wrong with on the spot mixing and carbonating dispensers like used by the fast-food chains for delivering these type of drinks as you only need to ship the concentrate.
