Prior studies have estimated that a liter of bioethanol requires 263-784 L of water from corn farm to fuel pump, but these estimates have failed to account for the widely varied regional irrigation practices. By using regional time-series agricultural and ethanol production data in the U.S., this paper estimates the state-level field-to-pump water(More)
Mercury emissions in China have increased by 164% during 1992-2007. While major mercury producers were among energy combustion and nonferrous metal sectors, little is known for the socioeconomic factors driving the growth of emissions. In this paper we examine the underlying drivers and their contributions to the change of mercury emissions. Results show(More)
[COMMENTS ON TEXT BY TSU TO REVIEWER: This chapter has been allocated 60 template pages 1 (plus an additional 8 for the bioenergy annex). It currently counts 72 (plus an additional 18 bioenergy 2 pages), so it is 12 pages over target (plus an additional 10 bioenergy pages). Reviewers are kindly 3 asked to indicate where the chapter could be shortened.] 4
Current economic restructuring policies have ignored unintended environmental consequences and cobenefits, the understanding of which can provide foundations for effective policy decisions for green economy transformation. Using the input-output life cycle assessment model and taking China as an example, we find that household consumption, fixed capital(More)
To build a life cycle assessment (LCA) database of Japanese products embracing their global supply chains in a manner requiring lower time and labor burdens, this study estimates the intensity of embodied global environmental burden for commodities produced in Japan. The intensity of embodied global environmental burden is a measure of the environmental(More)
Four Korean native cattle (KNC) breeds-Hanwoo, Chikso, Heugu, and Jeju black-are entered in the Domestic Animal Diversity Information System of the United Nations Food and Agriculture Organization (FAO). The objective of this study was to assess the genetic diversity, phylogenetic relationships and population structure of these KNC breeds (n = 120) and(More)
Life Cycle Assessment (LCA) evaluates the environmental impact of a product through its entire life cycle, from material extraction to final disposal or recycling. The environmental impacts of an activity depend on both the ac-tivity's direct emissions to the environment as well as indirect emissions caused by activities elsewhere in the supply chain. Both(More)
Life Cycle Assessment (LCA) is the study of the environmental impact of products taking into account their entire lifespan and production chain. This requires gathering data from a variety of heterogeneous sources into a Life Cycle Inventory (LCI). LCI preparation involves the integration of observations and engineering models with reference data and(More)
