A fuel-based approach is used to estimate long-term trends (1990–2010) in carbon
monoxide (CO) emissions from motor vehicles. Non-methane hydrocarbons (NMHC) are …

A fuel‐based approach is used to estimate nitrogen oxides (NOx= NO+ NO2) emissions from
gasoline‐and diesel‐powered motor vehicles. Estimates are made at the national level for …

Gas-and particle-phase pollutants were measured separately for (a) light-duty (LD) vehicles
and (b) medium-duty (MD) and heavy-duty (HD) diesel trucks. Measurements were made …

Accurate emission inventories and their temporal trends must be incorporated into pollutant
inventories to allow for reliable modeling of the country's past, present, and future air quality …

On-road vehicles continue to be a major source of nitrogen oxide (NO x) emissions in the
United States and in other countries around the world. The goal of this study is to compare …

Nitrogen oxides (NO x= NO+ NO 2) emitted by on-road combustion engines are important
contributors to tropospheric ozone production. The NO x fraction emitted as nitrogen dioxide …

This paper provides estimates of emissions of two important but often not well-characterized
greenhouse gas (GHG) emissions related to transportation energy use: methane (CH 4) and …

A fuel‐based inventory for vehicle emissions is presented for carbon dioxide (CO2) and
mapped at various spatial resolutions (10 km, 4 km, 1 km, and 500 m) using fuel sales and …

Mobile emissions represent a significant fraction of the total anthropogenic emissions
burden in the Mexico City Metropolitan Area (MCMA) and, therefore, it is crucial to use top …

Ambient measurements of hydrocarbons, carbon monoxide and nitrogen oxides from three
mega-cities (Beijing, Mexico City, Tokyo) are compared with similar measurements from US …
