Sending air mail is a luxury now? Global aviation produces something like 2% of global co2 emissions As for shipping, it uses 4.5% of global co2 emissions. Source https://www.theguardian.com/environment/2008/feb/13/climatechange.pollution https://www.theguardian.com/environment/2008/feb/13/climatec... What's more, here is what @BurnGpuBurn [1] pointed out before: "Shipping also very often uses the dirtiest of fuels and is therefore much more polluting than airliners which burn quite high quality refined fuels. That's why, to get around recent laws limiting sulfur emissions, large container boats now first "scrub" their exhaust gasses with sea water, so all sulfur will now nicely pollute and acidify our oceans. [0] No emissions though, because emissions bad." [0] http://www.imo.org/en/MediaCentre/HotTopics/Pages/Sulphur-2020.aspx http://www.imo.org/en/MediaCentre/HotTopics/Pages/Sulphur-20...

So similar emissions, but only one of them transports 90% of the worlds goods, raw materials and waste. > Sending air mail is a luxury now? Yes - either wait a bit longer if you need to send a physical thing - or if it's just a message then do it electronically. Yes - perhaps an email isn't as 'nice' as a real letter, but isn't that the definition of luxury?

  > So similar emissions Did you read my 2nd point? The emissions are not similar. Please also follow up on the source I've provided.

    Not saying boats are perfect or that every company that runs them are angels! But you have a lot of head-room if you start off 100x better kg per kg. Because boats are not perfect doesn't change the original point: A 20% saving on emissions for aircraft and talk of 'having more space for cargo' is missing the big picture - air travel is a massively subsidized luxury where the speed of travel comes at a massive energy cost.
