CETIOM, Centre de Grignon, Avenue Lucien-Brétignières, 78850 Thiverval-Grignon, France Abstract: In order to estimate the environmental impacts of first generation biofuels produced in France, a Life Cycle Assessment (LCA) was conducted in 2009 and published in the beginning of 2010. However, there have been discrepancies in the interpretation of the results of this study. Th...

Climate change is seen as a major threat to the survival of many species, ecosystems and the sustainability of livestock production systems in many parts of the world. Green house gases (GHG) are released in the atmosphere both by natural sources and anthropogenic (human related) activities. An attempt has been made in this article to understand the contribution of ruminant livestock to climate...

We develop a two-region partial equilibrium model of the global market for liquid fuel and analyze different policies, such as biofuel mandate, emission standard, and fuel carbon tax. We rank these policies under different criteria, such as greenhouse-gas (GHG) emissions, expenditure on fuel imports, the impact on fuel consumers and producers, the quantity of biofuel, etc. Our analysis suggests...

Greenhouse Gas (GHG) emissions from the offshore fisheries industry in the Republic of Korea (Korea) were examined in response to growing concerns about global warming and the contribution of emissions from different industrial sectors. Fuel usage and GHG emissions (CO2, CH4, N2O) were analysed using the 'Tier 1' method provided by the Intergovernmental Panel on Climate Change (IPCC) from the o...

Based on the carbon-nitrogen cycles and greenhouse gas (GHG) mitigation and emission processes related to straw return and burning, a compound greenhouse gas budget model, the "Straw Return and Burning Model" (SRBM), was constructed to estimate the net mitigation potential of straw return to the soil in China. As a full GHG budget model, the SRBM addressed the following five processes: (1) soil...

Ambitious climate change mitigation requires the implementation of effective and equitable climate policy and GHG emission reduction measures. The objective of this study was to explore the significance of the uncertainties related to GHG emission reduction measures and policies by providing viewpoints on biofuels production, grid electricity consumption and differentiation of emission reductio...

Livestock is a vital source of methane and nitrous oxide gas which are considered as hazardous greenhouse gas (GHG) causing global warming. This study was conducted to assess GHG emissions from different livestock categories of different (small, medium, large) dairy farming in Bangladesh by using IPCC guideline 2006 and CIGR 2002. The emission rate of CH4, N2O (mainly emits from manure) is incr...

Uncertainty analysis of greenhouse gas (GHG) emissions is becoming increasingly necessary in order to obtain a more accurate estimation of their quantities. The Monte Carlo simulation (MCS) and non-parametric block bootstrap (BB) methods were tested to estimate the uncertainty of GHG emissions from the consumption of feedstuffs and energy by dairy cows. In addition, the contribution to variance...

Anthropogenic greenhouse gas (GHG) emissions have substantially contributed to intensification of heavy precipitation and thus the risk of flood occurrence, and this anthropogenic climate change is now likely to continue for many centuries. Thus, precise quantification of human-induced GHG emissions is urgently required for modeling future global warming and precipitation changes, which is stro...

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...
