【 摘 要 】

The recent article in this journal of Cerri et al. (2016) gives estimates of greenhouse gas (GHG) emissions for cattle production on extensively managed farms in the State of Mato Grosso, Brazil. The results are expressed as GHG emission per kg of animal in the herd, and not per kg of product. These estimates should not be referred to as carbon footprints as they do not reflect the estimate of the GHG emissions utilized in the production of 1 kg of animal or carcass, but the total emission per kg of the total mass of animals in the herd, whether calves, heifers, steers or mature bulls and cows. This leads to a large underestimation of the true GHG emissions for the production of Brazilian beef. (C) 2016 Elsevier Ltd. All rights reserved.
