I gather you are referring to the oft-quoted stat about the cargo ship being "more polluting" than so many millions of cars? That is referring specifically to SOx I believe. It definitely is not referring to carbon emissions. Container ships have the lowest gCO2/(km*kg)
- close04 7y agoIt was more generic than that (see mention of beyond carbon). Otherwise we’d still be heavily promoting diesel as the clean alternative to gasoline. The cargo ship was just something to exemplify the point of taxing for destroying the environment. You’re free to pick any example you feel suits better and the principle will still apply.
- SECProto 7y agoI'm all in favour of carbon tax to reduce emissions. They would result in pressure for electric vehicles of all sorts, improve the economics for renewable electricity, maybe increase funding availability for carbon capture research. Cargo ships would likely stay the same for a long time in the future (but might implement fuel reduction techniques that are at a lower TRL (thinking specifically of a long lead parasail/kite that I read about a couple years back)
