"Not only [do other drinks] taste better, but it also helps to cut carbon emissions by reducing the number of miles needed to transport [it]."
I walk in to work. If there were no cars around it would be quieter for me. Walking to work might cut carbon emissions. Ban cars.
"Not only [is walking more pleasant], but it also helps to cut carbon emissions by reducing the number of miles [we drive]."
It's quite simple really. Combine an arrogant willingness to impose the choices you prefer, or find convenient, on everyone else for no good reason with an appeal to the global warming omni-justification and you can justify banning anything you vaguely dislike. Gordon Ramsay's call to ban out-of-season produce is illiberal nonsense.
