摘要: Agriculture is a significant source of anthropogenic greenhouse gas (GHG) emissions, and beef cattle are particularly emissions intensive. GHG emissions are typically expressed as a carbon dioxide equivalent (CO 2 e)'carbon footprint'per unit output. The 100-year Global Warming Potential (GWP 100) is the most commonly used CO 2 e metric, but others have also been proposed, and there is no universal reason to prefer GWP 100 over alternative metrics. The weightings assigned to non-CO 2 GHGs can differ significantly depending on …
