Can Responsible Grazing Make Beef Climate-Neutral? New research found that the greenhouse gases sequestered in one grass-fed system balanced out those emitted by the cows, but some meatless advocates are skeptical.
Impacts of soil carbon sequestration on life cycle greenhouse gas emissions in Midwestern USA beef finishing systems This study, published in Agricultural Systems, examines the carbon output and sequestration of feedlot produced cattle and multi-paddock grazed cattle.
Soil, Carbon, and Organic Farming. The Soil Association. This summary report discusses the implications of grass-fed animal production on climate change. Pastures planted in grass for grazing help with the carbon sequestration in soil, and may off-set the methane produced from the grazing animals.
Tackling Climate Change through Livestock. FAO The beef industry has the difficult challenge of having to reduce its GHG emissions while responding to a significant demand growth for livestock products (projected to be +70 percent between 2005 and 2050), driven by a growing world population (9.6 billion by 2050), rising affluence and urbanization (from the report). Carbon sequestration from grazing is a factor to consider as part of climate change mitigation, but carbon and methane emissions may also be mitigated with in-system efficiency improvements.
