Maybe it's just me, but I think this test avoids some questions I expected there, and does so in a very contrived manner.
"Switch to Electric" is favorably compared to "Hitch a Ride", and then "Hop on the Bus" is unfavorably compared to "Ships ahoy".
The overall impression I take is something like: "just wait and see, some guys are working on hard engineering problems wrt ships and planes, you save for your Tesla while eating plants and you'll be doing your part".

- sp332 9y agoRelatively speaking, I think far more attention has been given to reducing emissions from passenger cars than from shipping, even though it's a much smaller source of CO2. So it's an interesting comparison.
- tgb 9y agoI think you're mistaken that passenger cars are the smaller part. I'm struggling to find a clear source but pg 45 of this [1] shows passenger cars as 50% of total transportation energy (including road freight and shipping, I think) and page 35 projects passenger cars as 43%, compared to 8% for shipping, of CO2 emissions in 2050. You might be mixing up CO2 emissions with Sulfur emissions [2] [1] https://www.iea.org/publications/freepublications/publication/transport2009.pdf https://www.iea.org/publications/freepublications/publicatio...

- mikeash 9y agoIs it much smaller? I'm having trouble finding good numbers, but what I can find seems to put cars and ships at a similar level.
