An integrated approach for estimating greenhouse gas emissions from 100 U.S. metropolitan areas (12 page pdf, Samuel A Markolf, H Scott Matthews, Inês L Azevedo and Chris Hendrickson, Environmental Research Letters, Jan. 25, 2017)
Today we review an approach to estimate the emissions for a large number of cities in the USA which has advantages over the traditional bottom-up approach as well as likely being more accurate because it includes production as well as consumption of carbon emissions and fuels. Emissions from individual cities ranged from 5 metric tons per person in Tucson to 65 meteric tons per person in New Orleans. In gross terms, the average emission for the 100 cities examined was 27 million metric tons per year.
