System behaviour was tested for the impact of interventions on energy efficiency and methane output by using simulation models. Compensatory carbon sequestration area was calculated for 31 beef production enterprises with three levels of production intensity using a ?carbon footprint? type of accounting. Evaluation of water productivity was carried out by calculating ?virtual water contents? for three levels of production intensity typically found in South America.  aCarne  aEfeito Estufa  aImpacto Ambiental  aMeio Ambiente  aBovino de corte1 aBUNGENSTAB, D.
