This is no loss for me, because I am vegan. But soon I make a truly unsettling discovery. Sherry, alcoholic drink – and definitely not just for grandmothers – has emissions of 4.27g Co2e per kg, which is higher than some of the most notorious offenders, including meats like pork and sausages. Port-drinkers will be relieved to hear that its emissions remain a mystery, though it seems likely both fortified wines would have similar impacts.
