Book (stand-alone)Global database of GHG emissions related to feed crops - Methodology 2017
Also available in:
No results found.This report presents the information on the background to the study, the approach and methodology applied. It also presents and discusses the results from the analysis of GHG emissions. An accompanying document “A life cycle inventory for wheat, maize, barley, soybean and cassava” provides more detailed information on the life cycle inventory (LCI). Section 2 and 3 of this report presents a brief overview of the global feed sector and crop production practices, respectively. Section 4 provides a n overview of the approach and methodology applied in the assessment of GHG emissions for the five crops. This information is supplemented by an accompanying document that presents background information on the life cycle inventories of the crops. Section 5 and 6 presents an initial discussion on uncertainty and key challenges and future work that will be undertaken. -
Book (stand-alone)Greenhouse gas emissions from pig and chicken supply chains – A global life cycle assessment
A global life cycle assessment
2013Also available in:
No results found.The livestock sector is one of the fastest growing subsectors of the agricultural economy, and faces several unprecedented and concomitant challenges. The sector needs to respond to the increasing demands for livestock products that are arising from population growth and changing consumer preferences. It also has to adapt to changes in the economic and policy contexts, and in the natural environment upon which production depends. At the same time, it has to improve its environmental performanc e and mitigate its impact on climate. The pig sector is the biggest contributor to global meat production, with 37 percent in 2010. Chicken meat accounts for about 24 percent. Global demand for pig meat, chicken meat and chicken eggs are forecast to grow by 32 percent, 61 percent and 39 percent respectively during the period 2005-2030. If the greenhouse gases (GHG) emissions intensities (emission intensity; or the kg of GHG per kg of product) of these commodities are not reduced, the increa ses in production required to meet demand will lead to proportionate increases in GHG emissions. Improving our understanding of where and why emissions arise in livestock supply chains is an important step towards identifying ways to improve efficiency and reduce emissions intensity. This report presents a life cycle assessment (LCA) of the GHG emissions arising from pig and chicken supply chains. It provides a detailed analysis of emissions according to region, sector and systems of product ion. In addition to informing efforts to reduce GHG emissions, it is hoped that the assessment will also help inform public debate on this important subject. -
Book (stand-alone)Greenhouse gas emissions from ruminant supply chains – A global life cycle assessment
A global life cycle assessment
2013Also available in:
No results found.In decades to come, the global demand for livestock products will continue to increase driven by growing populations, incomes and urbanization. As a consequence the sector needs to produce more but in a context of increasing natural resource scarcity and challenges posed by climate change. In 2010, the ruminant sector contributed about 29 percent to global meat production (equivalent to 81 million tonnes) of which 79 percent is from the cattle sector and the remaining from buffalo and small ruminants. Global milk production in 2010 was 717 million tonnes with milk production from the cattle sector contributing the bulk, about 83 percent of global production. While ruminants play an important role in providing high quality protein essential for human diets, they are an important source of greenhouse gas (GHG) emissions. The demand for bovine meat, mutton and milk is forecasted to grow at a rate of 1.2 percent, 1.5 percent and 1.1 percent, respectively, during the period 2006-205 0. To avoid significant increases in total GHG emissions from the sector, a reduction of the intensity of emissions is required. This report presents a life cycle analysis of the GHG emissions arising from ruminant supply chains around the year 2005. This first comprehensive and disaggregated global assessment of emissions enables the understanding of emission pathways and hotspots. This is a fundamental and initial step to identify mitigation strategies and inform public debate.
