Measuring Carbon Dioxide Emissions from Road Transport

Publication | December 2008

Present information on carbon emissions is scant and misleading. Fuel sales give aggregate measure but not details. There is little independent information on vehicles, usage, fuel, or CO2 emissions per kilometer.


  • Transport is the fastest growing carbon dioxide (CO2) emitter.
  • You can't fix what you can't measure.
  • Enhanced planning, use of technology, and incentives are "smart transport" options.
