The measurement of greenhouse gas (GHG) emissions from urban centers in Europe and the U.S. is of extreme interest to academic researchers, government agencies, non-governmental organizations, and industry.  This interest is being driven by the fact that the identification and quantification of GHG emissions enables policy makers to make informed, metrics-based decisions and to incentivize changes in transportation and land use patterns. In addition, anticipated regulatory changes to GHG emissions requirements, as well as recent claims by the natural gas industry that natural gas is the clean fuel of the future, have given rise to even more interest.
Utilizing a variety of measurement tools, including networks of analyzers, flux measurements, and measurements taken by aircraft and cars, just to name a few, knowledge about urban-scale GHG emissions is quickly growing. 

This session is open to those focused on efforts to measure and quantify GHG emissions at the facility-level, the neighborhood-level, and also at city and regional scales. We welcome those involved with GHG concentration and emissions measurements around urban centers to present their work.
