- The exact number of light-duty commercial vehicles and heavy-duty trucks is indeterminable from the statistics provided by the Department of Transportation.
- There were 141,872,000 commercial vehicles in use in the United States in 2015.
- According to Denso, there were 18,000 heavy-duty and off-road vehicles in operation in the US in 2017.
- In 2017, the total GHG emission in the United States was 6,456.7 Tg CO2-e.
- The total GHG emission in the transportation sector was 1,867.1 Tg CO2-e.
- Emissions from on-road vehicles were 1,558.6 Tg CO2-e.
- Emissions from light-duty trucks were 327.3 Tg CO2-e. This represents 5.07% (327.3 Tg/6,456.7 Tg) of all GHG emissions.
- Emissions from medium-and-heavy-duty trucks were 436.5 Tg CO2-e. This represents 6.76% (436.5 Tg/6,456.7 Tg) of all GHG emissions.
We first searched government databases for the number of light-duty and heavy-duty trucks, however, the information we found did not provide the vehicle count specific to light-duty and heavy-duty trucks. We also searched vehicle-in-operation statistics for the two CV segments in ACT Research, IHS Markit, and Experian reports and industry association websites but did not find the required data. Most statistics we came across was for light vehicles as a whole. Alternately, we looked for the data in CV supplier annual reports (for references on market size) and related media reports but met with limited success.
