Food and Agriculture Organisation says farmers can slash emissions merely by adopting better methods
Greenhouse gas emissions from livestock could be cut by up to 30% if farmers adopt better techniques without having to overhaul entire production systems, according to a study released on Thursday by the UN Food and Agriculture Organisation (FAO).
The FAO said emissions associated with livestock added up to 7.1 gigatonnes (GT) of carbon dioxide equivalent (CO2-eq) per year - or 14.5% of all human-caused greenhouse releases, slightly less than its controversial estimate in 2006.
In its highly influential report seven years ago, Livestock's Long Shadow, the FAO said global meat production was responsible for 18% of greenhouse gas emissions - a little more than all of the world's cars, trains and planes combined. Environmentalists and, in particular, vegetarian advocacy groups have cited the figure ever since as a key reason to reduce meat consumption.
