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...

GHG emission reduction is one of the key environmental problems for the sustainable development discussion in the 21st century, because it is closely related to energy use and bulk material flows. Concrete and binding targets for reduction of greenhouse gas (GHG) emissions for Annex-1 countries are now agreed to in the Kyoto protocol. Emissions in the European Union will be reduced by 8% in the...

Automotive manufacturing is energy-intensive. The consumed energy contributes to the generation of significant amounts of greenhouse gas (GHG) emissions by the automotive manufacturing industry. In this paper, a study is conducted on assessing the application potential of such clean energy power systems as solar PV, wind and fuel cells in reducing the GHG emissions of the global auto manufactur...

This Symposium has focused primarily on recent efforts by several states of the United States to regulate greenhouse gas (GHG) emissions. These state-level efforts include common law liability actions (such as public nuisance lawsuits) brought by several states against large GHG emitters.1 They also include states’ regulation of GHG emissions from mobile sources (such as California’s 2002 law r...

Agriculture is a source for three primary greenhouse gases (GHGs): CO2, CH4, and N2O. It can also be a sink for CO2 through C sequestration into biomass products and soil organic matter. We summarized the literature on GHG emissions and C sequestration, providing a perspective on how agriculture can reduce its GHG burden and how it can help to mitigate GHG emissions through conservation measure...

This article describes and analyses each level of governance relevant to address climate mitigation within France. This refers either to climate policies or to measures adopted for other reasons but which impact on greenhouse gas (GHG) emissions. The first part describes the French context related to GHG emissions to emphasize the importance of taking into account local specificities when consi...

greenhouse gas (gHg) emissions from agriculture, including crop and livestock production, forestry and associated land use changes, are responsible for a significant fraction of anthropogenic emissions. using data from a new gHg global database developed at FAO, we focus on global indicator trends in the agriculture sectors, in relation to the carbon intensity of key food commodities. in partic...

The goal of this review was to analyze published data on animal management practices that mitigate enteric methane (CH4) and nitrous oxide (N2O) emissions from animal operations. Increasing animal productivity can be a very effective strategy for reducing greenhouse gas (GHG) emissions per unit of livestock product. Improving the genetic potential of animals through planned cross-breeding or se...

Greenhouse gas (GHG) emissions from community waste generation can represent a significant portion of a city, county, or region’s GHG emissions inventory. Estimating a jurisdiction’s emissions from this source can be challenging, since the waste generated by one community is sometimes exported to other communities for disposal. Current inventory protocols allow local governments to estimate was...

To analyse trends in greenhouse gas (GHG) emissions from production and consumption of animal products in Sweden, life cycle emissions were calculated for the average production of pork, chicken meat, beef, dairy and eggs in 1990 and 2005. The calculated average emissions were used together with food consumption statistics and literature data on imported products to estimate trends in per capit...
