Piper PA-38 Tomahawk CO₂ emissions per flight hour
Piper designed the two-seat PA-38 Tomahawk as a trainer and built it from 1978 to 1982. It has a low wing, a T-tail and a 112 hp Lycoming O-235, the same engine family that powers the Cessna 152. At a typical fuel flow of 6.5 US gallons (25 L) of avgas per hour, a Piper PA-38 Tomahawk puts about 54 kg of CO₂ into the air for every hour flown.

A year of flying in a Piper PA-38 Tomahawk
| Hours flown | CO₂ | Cost to offset |
|---|---|---|
| 25 h | 1.35 t | $47.25 |
| 50 h | 2.70 t | $89.78 |
| 100 h | 5.40 t | $160.65 |
| 200 h | 10.80 t | $321.30 |
Costs are for the yearly plan, from $0.035 per kg with lower rates as the amount grows. The monthly plan is $0.036 per kg, and one tonne once is $40.
On the monthly plan, offsetting an hour in a Piper PA-38 Tomahawk costs about $1.94. See plans

How we calculate this
Burning one US gallon of avgas releases about 8.31 kg of CO₂, so CO₂ per hour is fuel flow multiplied by 8.31. The figure covers combustion only, not producing or transporting the fuel.
Your real fuel flow depends on power setting, mixture, altitude and how much of the hour you spend climbing. If your logs give you an average burn, multiply it by 8.31 for a closer number.
