What exactly are you saying is equal to "about one air passenger trip to Europe"? OP says 85 kg/year of Carbon per really big tree. The first calculator I tried said a one way trip from NYC to London on a 787 is over 1000 kg of CO2: https://co2.myclimate.org/en/portfolios?calculation_id=6796040 https://co2.myclimate.org/en/portfolios?calculation_id=67960... Now, C is about 25% of the weight of CO2, so this would be 250 kg of Carbon. Is the calculator overestimating? Is my math wrong? Am I interpreting you wrong? Or are you low by a factor of 3?

> Is the calculator overestimating? Maybe. My own calculus gives a first approximate value of 50Kg of Carbon for the same trip NY-London (approx 5570Km) in optimum conditions. The calculators forget also that sometimes tail winds can help, so is just an unsophisticated raw average. In any case nothing prevent us to design hybrid planes to reduce the fuel consume. A turbine is just a motor so can be built in several different ways. And we could try also both things, hybrid planes and helping forests at the same time.
