How to Calculate and Offset Your Flight’s Carbon Emissions

Knowing how to calculate flight carbon emissions is the first step toward reducing your aviation footprint. Whether you’re a weekend pilot or a flight instructor, measuring your flight’s CO₂ output gives you the power to offset it—and TrimCarbon’s free Flight Emissions Calculator makes it quick and precise.

Calculating Your Flight’s Carbon Footprint

Using the Calculator: Step by Step

Select your aircraft type
Enter flight hours or fuel burn
Review your CO₂ estimate

TrimCarbon’s calculator draws on verified data for common GA planes, so you can trust the numbers you see.

Manual Estimation

If you prefer a hands‑on approach, estimate based on fuel burn:

Avgas emits ~3 kg CO₂ per liter.
Example: A 2‑hour flight in a Cessna 172 burns ~100 L, producing ~0.3 tonnes of CO₂.

Interpreting Your Results

When your calculator shows “0.3 tonnes CO₂,” that’s roughly:

750 miles driven by an average passenger car
A household’s annual CO₂ emissions for two weeks

Even short hops add up fast—so seeing the real numbers helps put things in perspective. TrimCarbon’s clear output ensures pilots grasp their impact at a glance.

Offsetting Your Emissions

Once you know your CO₂ amount, converting it into offsets is straightforward:

Choose offset method: by flight hours or by CO₂ tonnage
Pick one‑time or subscription
Complete your purchase

For a 0.3 tonne flight, at ~$15/tonne, you’d invest ~$4.50 in quality removal credits. Head to the TrimCarbon Flight Emissions Calculator page to offset now.
