The U.S. Department of Energy (DOE) estimates that in the coming decades the United States' natural gas (NG) demand for electricity generation will increase. Estimates also suggest that NG supply will increasingly come from imported liquefied natural gas (LNG). Additional supplies of NG could come domestically from the production of synthetic natural gas (SNG) via coal gasification-methanation....

s the scientifi c evidence of global climate change continues to accumulate (IPCC, 2007) and the predicted impacts of a warming planet become more widely known, national policies and international agreements designed to mitigate global warming have sought to strike a balance between environmental sustainability and economic achievement. Agriculture is at the center of this balancing act. On the...

This article assesses marginal greenhouse gas (GHG) emissions of electricity generation in Portugal to understand the impact of activities that affect electricity demand in the near term. In particular, it investigates the introduction of electric vehicles (EVs) in the Portuguese light-duty fleet considering different displacement and charging scenarios (vehicle technologies displaced, EV charg...

It is widely considered that the continued development and production of Alberta’s oil sands deposits is on track to be the fastest growing source of greenhouse gas (GHG) emissions in Canada over the next few decades. As recent developments suggest, failure to address the issue of GHG emissions growth might jeopardize the potential for sustained expansion of oil sands operations in Alberta. Wit...

Liquid transportation fuels derived from coal and natural gas could helpthe United States reduce its dependence on petroleum. The fuels could be produced domestically or imported from fossil fuel-rich countries. The goal of this paper is to determine the life-cycle GHG emissions of coal- and natural gas-based Fischer-Tropsch (FT) liquids, as well as to compare production costs. The results show...

Introduction According to the Fourth IPCC Assessment Report on Climate Change (AR4), anthropogenic greenhouse gas (GHG) emissions are responsible for a major part of the observed global warming over the past 50 years. In addition carbon dioxide (CO2), released from the burning of fossil fuels and biomass (e.g. burning of forest for land clearance) is recognized as the most important anthropogen...

Savanna fire is a major source of global greenhouse gas (GHG) emissions. In Australia, savanna fire contributes about 3% of annual GHG emissions reportable to the Kyoto Protocol. In order to reduce GHG emissions from savanna burning, the Australian government has developed and approved a Kyoto compliant savanna controlled burning methodology-the first legal instrument of this kind at a global l...

INTRODUCTION U.S. greenhouse gas (GHG) emissions rose 16 percent between 1990 and 2004, while those from light-duty vehicles rose 23%. (EPA 2006) During the same period, GDP increased 51% (BEA 2005) and VMT rose 37% – more than doubling the nation’s population increase. (Davies et al. 2007 and EPA 2006) While GHGs are on the rise, public policy can result in substantial energy savings. U.S. Cor...

Information and Communication Technology has a significant footprint in global resource consumption, greenhouse gas (GHG) emissions and waste, particularly considering the high growth rates. Yet, intelligent use of ICT can support other domains in mitigation (e.g. in reducing GHG emissions and resource consumption), monitoring of resources and environmental impacts and adaptation to unavoidable...
