When interpreting statements like "Over all, air travel accounts for about 2.5 percent of global carbon dioxide emissions", keep in mind that air travel emissions are higher impact due to occurring in the upper atmosphere. The commonly established multiplier is 2.7X [0]. So while the claim is 2.5% of global co2 emissions, in terms of impact it's more like ~6.7%. And growing, largely just so people can take selfies in different places, which are then used to promote more travel via social media. We need to tax fuel used for international air travel. The Chicago Convention [1] may have made sense in establishing the industry but we're well past that point now. Make this high-speed, high-impact transportation method high-cost so it's used less frivolously.
