NGVAmerica Serves Up Resource on GHG Emission Metrics

0

NGVAmerica has released a new white paper offering a high-level overview of greenhouse gas (GHG) emission metrics and their associated time frames.

“To understand the impact of different policy options on climate change, the scientific community developed emission metrics for calculating potential climate impacts of different greenhouse gases,” explains Dan Bowerson, NGVAmerica’s director of technology and development. “There are several metrics for analyzing greenhouse gases, and there is some debate about which methods are most appropriate. This white paper explains the differences in emission metrics and when one may be used over another.”

According to NGVAmerica, natural gas use in transportation provides an immediate reduction in long-lived carbon-dioxide emissions. The natural gas vehicle (NGV) industry is demonstrating its ability to dramatically reduce the amount of methane emitted along the whole supply chain, the group says.

The white paper is a product of NGVAmerica’s emissions and environmental work group, comprising multiple NGVAmerica members: Gas Technology Institute, Shell, Hexagon Composites, Gladstein, Neandross & Associates, Clean Energy, Agility Fuel Solutions, Cummins Westport, Westport, Puget Sound Energy, SDJ Industries, American Gas Association, Clean Fuels Consulting, SoCal Gas, and Argonne National Laboratory of the U.S. Department of Energy. Ted Barnes (Gas Technology Institute), Roxanne Bromiley (Shell) and Dan Bowerson (NGVAmerica) led the document’s drafting.

A copy of the white paper, Understanding Global Warming Potential and Other Greenhouse Gas Emission Metrics, is available here.
