Study on Greenhouse Gas Emissions from Global Cities Highlights Importance of Geophysical and Technical Factors

Green Car Congress

An international study of 10 global cities found that a balance of geophysical factors (climate, access to resources, and gateway status) and technical factors (power generation, urban design, and waste processing) determine the greenhouse gas emissions (GHGs) attributable to cities.

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Quantitative use of this indicator ratio is subject to three major uncertainties: (1) the split between NO x -limited and NO x -saturated conditions may shift in space and time, (2) the ratio of the vertically integrated column may not represent the near-surface environment, and (3) satellite products contain errors.

Study finds 2008 recession contributed to increase in age of US LDV fleet, slowing of emission reductions

Green Car Congress

The global economic recession of 2008—which severely depressed light-duty vehicle sales—resulted in an increase in the age of the light-duty vehicle fleet in the US that likely slowed the rate of decrease of fleet average emissions, according to a study by Gary Bishop and Donald Stedman at the University of Denver.
