CO₂ Emissions
Calculator
Calculate the tons of CO₂ your fleet generates every month based on fuel consumed. Compare against the industry average and find out how many trees you'd need to offset it.
The CO₂ emissions of a diesel freight truck in Mexico are approximately 2.68 kg of CO₂ per liter of diesel consumed — a tractor-trailer that consumes 800 liters a month generates around 2.1 tons of CO₂ monthly. Knowing your fleet's emissions is increasingly relevant for government bids, ESG certifications and corporate sustainability reports. Enter the fuel and liters consumed to get the tons of CO₂ and the comparison vs the industry average.

How are CO₂ emissions calculated?
The formula
Multiply the liters consumed per unit by the fuel's emission factor and by the number of units in your fleet.

Frequently asked questions
How much CO₂ does a diesel truck emit per kilometer?
A diesel tractor-trailer emits on average between 0.75 and 0.90 kg of CO₂ per kilometer, depending on the load and engine efficiency. For a medium truck, the average is 0.42 kg/km. The diesel emission factor is 2.64 kg CO₂ per liter consumed.
How is a fleet's carbon footprint calculated?
You multiply the liters of fuel consumed by the emission factor: diesel = 2.64 kg CO₂/l, gasoline = 2.31 kg CO₂/l, CNG = 1.93 kg CO₂/l. Then multiply by the number of units and divide by 1,000 to get tons.
How many trees do I need to offset my fleet's emissions?
An adult tree absorbs approximately 22 kg of CO₂ per year, equivalent to 45 trees per ton of CO₂. This calculator automatically converts monthly tons of CO₂ into the number of trees needed to offset them.
Why does CNG emit less CO₂ than diesel?
Compressed Natural Gas has an emission factor of 1.93 kg CO₂/l, versus 2.64 for diesel, a 27% reduction. In addition, CNG emits fewer particulates and nitrogen oxides, improving local air quality.
How can I reduce my fleet's CO₂ emissions?
The main strategies are: improve fuel efficiency with preventive maintenance, optimize routes to reduce empty km traveled, train operators in efficient driving, and consider a gradual transition to CNG or more efficient units.
Emission factors are international standard values (IPCC / SEMARNAT). Mexico industry averages are indicative estimates for freight transport.
