The thing is, very few things is a large share of global carbon dioxide emissions. "It doesn't matter what Norway does because we're less than 1% of global emission" "It doesn't matter with air travel because it's only 2.5% of emissions" "It doesn't matter with coal power in Germany, because overall it's not that much" If the rest of the world has that attitude, it won't matter if China and the US (often cited as the ones that matter) get to zero, as that's still not enough. CO2 emissions is death by a 1000 papercuts, we need to tackle them all So yes, let's bring aviation under carbon tax and/or cap and trade schemes, then people can decide how much they're willing to pay for these emissions compared to other sector emissions. I would guess travel is something people value and would be willing to pay for, until there are better solutions available Note: I say this as someone that travel quite a bit for work and leisure - I would definitely be penalized if I have to pay for my emissions
