Natural gas and the greenhouse

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...

Understanding Greenhouse Gas Emissions from Unconventional Natural Gas Production

Natural gas comprises almost one-fourth of all energy used in the U.S. New technologies, sometimes referred to as “unconventional” have enabled the production of more natural gas and have expanded domestic energy reserves. Natural gas is generally recognized as a clean-burning fuel source, producing less greenhouse gas (GHG) emissions per quantity of energy consumed than either coal or oil. How...

A bridge to nowhere: methane emissions and the greenhouse gas footprint of natural gas

In April 2011, we published the first peer-reviewed analysis of the greenhouse gas footprint (GHG) of shale gas, concluding that the climate impact of shale gas may be worse than that of other fossil fuels such as coal and oil because of methane emissions. We noted the poor quality of publicly available data to support our analysis and called for further research. Our paper spurred a large incr...

The Greenhouse Gas Protocol

The Greenhouse Gas (GHG) Protocol Corporate Accounting and Reporting Standard provides a step-bystep guide for companies and government agencies to use in quantifying and reporting their GHG emissions. This set of standards was developed by the Greenhouse Gas Protocol Initiative, a partnership convened by the World Resources Institute (WRI) and the World Business Council for Sustainable Develop...
