Scientists Calculate Carbon Emissions of Your Sandwich
An anonymous reader shares a report: It's a staple of the British diet and a popular choice for a quick and easy lunch. But new research reveals the carbon footprint of the humble sandwich could be fuelling harmful greenhouse emissions. The worst offender is revealed as the ready-made "all-day breakfast" sandwich, crammed with egg, bacon and sausage. Researchers at the University of Manchester carried out the first ever study of the carbon footprint of sandwiches -- both home-made and ready-made. They considered the entire life cycle of sandwiches, including the production of ingredients, packaging, refrigeration and food waste. The team scrutinised 40 different sandwich types, recipes and combinations and found the highest carbon footprints for the sandwiches containing pork meat (bacon, ham or sausages) and also those filled with cheese or prawns. The researchers estimate that a ready-made (and highly calorific) all-day breakfast sandwich generates 1441g of carbon dioxide equivalent -- equal to the emissions created by driving a car for 12 miles (19km).Read more of this story at Slashdot.
