Carbon Footprint of Beef Cattle
The carbon footprint of beef cattle is presented for Canada, The United States, The European Union, Australia and Brazil. The values ranged between 8 and 22 kg CO2e per kg of live weight (LW) depending on the type of farming system, the location, the year, the type of management practices, the allocation, as well as the boundaries of the study. Substantial reductions have been observed for most...
متن کاملThe Carbon Footprint of Beef Production
Modern-day agriculture allows the average farmer to produce enough food to feed 125 other people. This is in sharp contrast to the historical agricultural systems exemplified by farming in the 1800s, when each farm could produce only enough food to feed one other family. The global population has increased in line with productivity, yet the rate of increase in meat consumption is greater than t...
متن کاملRole of dairy in the carbon footprint of US beef.
In PNAS, Eshel et al. (1) present a novel methodology for calculating a suite of ecological impacts from livestock and poultry production in the United States. The authors acknowledge two complementary and valuable approaches in ecological accounting: bottom up and top down. Top-down analyses, however, are only valuable insofar as they adequately represent the structure of the study system. By ...
متن کاملCarbon footprint and ammonia emissions of California beef production systems.
Beef production is a recognized source of greenhouse gas (GHG) and ammonia (NH(3)) emissions; however, little information exists on the net emissions from beef production systems. A partial life cycle assessment (LCA) was conducted using the Integrated Farm System Model (IFSM) to estimate GHG and NH(3) emissions from representative beef production systems in California. The IFSM is a process-le...
متن کاملIncluding carbon emissions from deforestation in the carbon footprint of Brazilian beef.
Effects of land use changes are starting to be included in estimates of life-cycle greenhouse gas (GHG) emissions, so-called carbon footprints (CFs), from food production. Their omission can lead to serious underestimates, particularly for meat. Here we estimate emissions from the conversion of forest to pasture in the Legal Amazon Region (LAR) of Brazil and present a model to distribute the em...
