Resumo: The debate on the relationship between human activities and the growth in the emissions of carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O) into the atmosphere has brought the need to study more deeply the relationship between productive activities and the emission of these greenhouse gases (GHG) (FAO, 2013). Thus, the definition of what changes should be implemented in the production process aiming to reduce GHG emissions level should also consider the economic and social sustainability of the activity (SILVA et al, 2016). Beef cattle in Amazon, as in most of Brazil, is also predominantly developed in an extensive manner (ALVIM et al, 2015). The North Region had in 2014 a cattle herd of 45,826,142 beef heads, which represented 22% of the whole national herd, with emphasis to State of Pará with 19,911,217 - 43% of the regional cattle (IBGE, 2016). The study on the effects of this activity on the environment and the search for alternatives to mitigate the negative impacts will enable the development of more sustainable livestock. The increase in the adoption of more sustainable livestock systems, especially from an environmental point of view depends on the establishment of incentives to producers and, therefore, it is essential to identify models which present these virtuous characteristics, as well as economic performance, in order to define strategies for this combination.
