Because organic production represents a sustainable alternative for the environment, we studied the greenhouse gas emissions of six farms, two intensive farms, two organic and two conventional of the same race and geographic location, all of diary production Results in absolute terms show the highest emissions per year in the organic farm Eco2 (674 t CO2 eq) that have greater resources and greater agricultural food autonomy than the rest. The greenhouse gas emissions obtained per hectare and year are similar to those obtained in the literature, corresponding lower emission to the farm Eco2 (2.61 t eq CO2/ha and year), which demonstrates the effectiveness self-sufficient system when studied per hectare of earth. Intensive farms get three times more emissions per hectare and year that conventional and organic Australian and French references, which demonstrates the effectiveness of the intensive Spanish dairy producer. Key words: sheep, organic, economic, greenhouse gases Introduction In recent years, European society has increased the interest in strengthening the structures that maintain the economic activities in rural areas. These activities are linked to the environment, trying to conserve and improve it and, at the same time, they strengthen the workforce of these areas. These activities include those related to livestock and agriculture. As a result of the climate change, the agricultural activities are being studied to make them sustainable economic sectors that do not increase the balance of greenhouse effect gases. Agriculture and livestock in Spain account for 11% of total dioxide emissions (CO2) equivalent, with an increase of 17% over the base year (Nieto & Santamaría, 2002). In addition, certified organic production allows binding of organic farming with the environment and promotes sustainable practices. There are authors who claim that organic farms have better environmental performance than conventional ones (Bochu et al. 2008). 229
