since the majority of wine is not sparkling, there is an opportunity to capture the carbon at the source (moreover, the carbonation occurs naturally, as opposed to be introduced artificially in sodas)
Should artificially carbonated beverage production be banned?
Should breweries and sparkling wine producers have to compete for a limited number of permits since their carbonation will be passed on to the consumer?
What other ideas could you imagine?
