This report sets out what we know about the food system’s contribution to greenhouse gas (GHG) emissions. Taking a life cycle perspective, it looks at how these emissions arise, both by life cycle stage (from plough to plate to bin) and by food type. It then explores the flip side of the coin: the global impact of a changing climate on how we grow, distribute, produce and consume food. We follow this with a discussion of the strengths and weaknesses of and challenges for the life cycle analysis methodology upon which the report has drawn.
