Stronger is Better for the Environment
It's a relatively simple equation. If drinkers consume the same number of alcoholic units (within the CMO guidelines) from stronger abv canned beers and ciders vs lower abv canned beers and ciders, then the negative impact on the environment is less. Switching from drinking two cans of 4% abv lager to one can of 8% abv lager for example, will reduce waste, raw material use and pollution, by as much as half.
