Dive Summary:

• According to a new study, food production makes up 29% of greenhouse gas emissions, almost twice the amount the United Nations has previously estimated.
• The new study took into account deforestation, fertilizer production, transport and storage, all of which are aspects of food production yet were rarely accounted for.
• The study did have some good news however, giving many examples of how cutting emissions could actually cut costs in many situations such as more efficient fertilizer production in China and eating more local lamb in Britain. 

From the article:

Food production accounts for up to 29 percent of man-made greenhouse gases, twice the amount the United Nations has estimated comes from farming, a study published on Wednesday said.

Looking at emissions across the food system - including forest clearance, fertiliser production and transport - rather than just farming itself - agriculture research organisation CGIAR said much more work was needed to cut climate change emissions from food.
