If you are flying with any regularity, you are completely exhausting your carbon budget. The remaining carbon budget is the CO2 if emitted will lead to 2C warming. IPCC estimates it to be 1150 GtCO2 in 2020 [1]. Which is ~140 tCO2/person over however many years we use to spend this. So if we want to limit warming to 2C by 2050, that leaves a budget of 4.7tCO2/person/year.
A transatlantic round-trip alone can be 2.3tCO2 [2].
The elephant in the room. Even one flight per year per person is basically too much. Flying, above all else, is how middle-class folks (like those in this thread) explode their carbon footprints. For obvious reasons very few of them want to hear this.
A transatlantic round-trip alone can be 2.3tCO2 [2].
