Piper PA-30 Twin Comanche CO₂ emissions per flight hour
The Piper PA-30 Twin Comanche is a four-seat light twin with retractable gear and two 160 hp Lycomings. The figure covers both engines together, at 75% power. At a typical fuel flow of 17.2 US gallons (65 L) of avgas per hour, a Piper PA-30 Twin Comanche puts about 143 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.
CO₂ per 100 nautical miles is CO₂ per hour divided by the cruise speed of 168 knots, times 100. It describes cruise: a climb burns more fuel for each mile.

GuideHow to cut your aircraft's fuel burn and CO₂Every US gallon of avgas you don't burn is 8.31 kg of CO₂ you don't emit. Leaning, power settings, altitude, ground time and maintenance, plus what unleaded fuel and electric trainers will and won't change.
