Assessing the fuel Use and greenhouse gas emissions of future light-duty vehicles in Japan
Reducing greenhouse gas (GHG) emissions is of great concern in Japan, as well as elsewhere, such as in the U.S. and EU. More than 20% of GHG emissions in Japan come from the transportation sector, and a more than 70% reduction in GHG emissions by 2050 has been projected as a feasible goal. It is …

Assessing Greenhouse Gas Emissions Mitigation Potential through the use of Forest Bioenergy
… offers opportunities to reduce greenhouse gas (GHG) emissions associated with fossil fuel use, reduce non-renewable energy consumption, and provide investment and employment in the forestry sector. These opportunities, however, must be considered within the broader contexts of forest systems. Of …

Economic and Environmental Impacts of Plug-in Hybrids and Battery Electric Vehicles: A Comparative Analysis
<p>Greenhouse gas (GHG) emissions from anthropogenic sources are the leading contributors to global climate change. Over the past century, GHG emissions have increased tremendously due to causes such as deforestation and the burning of fossil fuels. In the US, about 28% of these GHG emissions come …
