Leaking methane from natural gas vehicles: Implications for transportation policy in the greenhouse era

Life cycle assessment of greenhouse gas emissions from plug-in hybrid vehicles: implications for policy.

Plug-in hybrid electric vehicles (PHEVs), which use electricity from the grid to power a portion of travel, could play a role in reducing greenhouse gas (GHG) emissions from the transport sector. However, meaningful GHG emissions reductions with PHEVs are conditional on low-carbon electricity sources. We assess life cycle GHG emissions from PHEVs and find that they reduce GHG emissions by 32% c...

Policy Options for Controlling Greenhouse Gas Emissions: Implications for Agruculture

The pace of activity around climate change legislation picked up noticeably in 2007. The increased focus brought new legislative proposals to reduce greenhouse gas emissions (GHGs). These bills include cap-and-trade systems, and carbon taxes1 as well as energy bills that promote energy efficiency or renewables (Table 1). Many also include support for research and development for emission reduci...

Energy, Greenhouse Gas, and Economic Implications of Natural Gas Trucks

Until recently, natural gas was an also-ran in the sweepstakes for changing the face of transportation in the United States, even though expanded reliance on natural gas vehicles (NGVs) holds the promise of reducing carbon emissions, reducing dependence on oil, and even lowering transportation costs. Recently, however, interest in natural gas as a transportation fuel has grown, as shale gas res...
