In itself it represents about one sixth of the emissions of greenhouse gas. Livestock emit 7,1 gigatonnes of CO2 equivalent per year into the atmosphere, that is, 15% of all COXNUMX emissions. the origin anthropic.
But according to a new report from the Organization of Nations United for Food and Agriculture (FAO) published last Thursday, September 26, it is possible to reduce these by 30% emissions, using best practices and technologies existing.
El study, the most exhaustive carried out on this subject to date, has analyzed all the stages of the life cycle of the cattle raising: production and transport of feed for animals, energy use on the farm, emissions from digestion and fermentation of manure, as well as the transport, refrigeration and conditioning of products animals after sacrificing them.
The main sources of emissions: the production and transformation of forage (45%), specifically due to the Fertilizers chemical used in crops, the digestion of animals (39%), since cows emit methane, a gas 25 times more powerful than CO2, and the decomposition of manure (10%). The rest is attributable to the transformation and transportation of the products animal.
