What is the environmental impact of your lunch-time sandwich?

16 February 2018

Researchers studied the carbon footprint of sandwiches, both home-made and pre-packaged. They considered the whole life cycle of sandwiches, including the production of ingredients, sandwiches and their packaging, as well as food waste discarded at home and elsewhere in the supply chain.
The study concludes that the carbon footprint of the snacks could be reduced by as much as 50% if a combination of changes were made to the recipes, packaging and waste disposal. The researchers also suggest extending sell-by and use-by dates to reduce waste. An article about the research is published in Sustainable Production and Consumption (News Article The University of Manchester, 25 January 2018).
