The case for flat beer
The carbon footprint of a pint of beer:
300g CO2e: locally brewed cask ale at the pub
500g CO2e: local bottled beer from a shop or foreign beer in a pub
900g CO2e: bottled beer from the shop, extensively transported
Beer is unlikely to dominate your carbon footprint but it can make a significant contribution. According to my calculations, a few bottles of imported lager per day might add up to as much as a tonne of CO2e per year – equivalent to around 50,000 cups of black tea.
I promise not to drink so much black tea to make up for it. Of course Wadworth's still uses horses to deliver locally, though I guess the emissions form the beer fed horses are worse than CO2
