A new row has broken out over the environmental impact of the meat trade after a United Nations report was found to have exaggerated the proportion of greenhouse gas emissions caused by raising livestock.

A 2006 report, Livestock’s Long Shadow, claimed meat production caused 18% of global emissions – more than transport.

But critics said that figure included factors such as fertiliser production and land clearance – inflating the significance of the meat trade to global emissions.

“We factored in everything for meat emissions – and we didn't do the same thing with transport,” Pierre Gerber of the UN’s Food & Agriculture Organisation told the BBC.
