There are those of us that also think asking people to 'cut back' voluntarily like this is a fucked solution out of the gate.

I continue to fly across the country for work because refusing only hurts my career and gives me a slight sense of smug superiority. Someone else on standby would just take my seat anyway and my refusal would have had no impact (other than a negligible reduction in revenue for the airline).

Instead I actually do something that might have an impact and I donate to organizations researching alternative energy or just straight up planting trees.

I would rather just have the price of carbon emissions priced into the airline tickets than stupidly trying to shame anyone who travels.
