How to calculate vehicle idle emissions
This calculator estimates vehicle idle emissions by multiplying idle hours by emissions per hour.
How the calculation works
Idle emissions = Idle hours × Emissions per hour.
Example
40 idle hours at 22 lb CO2/hour (a commonly cited figure for a typical diesel truck at idle): 40×22 = 880 lbs CO2.

Pro Tips for Vehicle Idle Emissions
- Emissions per idle hour vary significantly by engine size — use a figure specific to your actual vehicle type.
- Anti-idle policies and automatic shutoff timers directly reduce this often-overlooked emissions source, alongside the fuel cost savings they provide.
Common Vehicle Idle Emissions Mistakes to Avoid
- Using a generic idle emissions rate across vehicles with very different engine sizes, which have meaningfully different actual idle emissions.
