but if you didn't board that flight, the flight would still happen, and the efficiency just dropped since it carried one less passenger.
Unless you can convince a large amount of passengers to not travel at all (and i meant not travel, rather than switch to a different mode of transport), there is no reducing carbon emissions.

At some point, less revenue = less flights. Even dropping demand by 200 people on a route would cause a reduction in flights. It's a long way off from making a huge impact, but individuals can decide how they want to vote with their dollar and every dollar and every reduction counts.
Sure, a huge reduction in carbon emissions will probably come from a technology breakthrough, but we can help accelerate the demand for that tech by reducing demand for current carbon emitting activities.
