Piper PA-44 Seminole CO₂ emissions per flight hour
The Piper PA-44 Seminole is a four-seat light twin with a T-tail and counter-rotating propellers, used by many flight schools for multi-engine training. The figure covers both 180 hp engines together. At a typical fuel flow of 23.4 US gallons (89 L) of avgas per hour, a Piper PA-44 Seminole puts about 194 kg of CO₂ into the air for every hour flown.

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.
