Have a look at cargo ship emissions and then think.
- lb1lf 10y agoWhich is why lots of very smart people spend lots of money figuring out better ways to power commercial shipping; gas turbines for instance - and even sails may make a comeback. The problem with cars (in particular diesel ones) is that their pollution causes problems locally, too. That is less of an immediate concern if you're plying the Yokohama-US Pacific coast route.
- robin_reala 10y agoI always liked the kite idea: http://www.skysails.info/english/skysails-marine/skysails-propulsion-for-cargo-ships/ http://www.skysails.info/english/skysails-marine/skysails-pr...
- sllabres 10y agoI don't negate that this is the case but bunker and "gas turbines" seems a bit on the opposite for fossile energy regarding the environment. And this fuel does not seem to loose attraction due to its price. "Worldwide bunker use in 2001 was estimated at 278 million tons, of which around 212 million tons were residual fuels. Between 2001 and 2020, total consumption grows at an average annual rate of 3.1% [...]" [1] [1] https://nepis.epa.gov/Exe/ZyPDF.cgi/P1001TZU.PDF?Dockey=P1001TZU.PDF https://nepis.epa.gov/Exe/ZyPDF.cgi/P1001TZU.PDF?Dockey=P100...
- lb1lf 10y agoI (partially) agree; however, we have a saying in Norway that "The best is the worst enemy of the good." In a perfect world, shipping would be emissions-free; however, it is not; the vast majority of the world's commercial shipping runs off heavy fuel oil. Getting it to pollute less in the short term is IMHO better than holding out, waiting for zero emissions somewhere down the line.
- raverbashing 10y agoWell, they don't run on Diesel, but something heavier
- adrianN 10y agoNOx from cargo ships are not really a problem. Those gases aren't very stable and don't kill the climate. They're just unhealthy to humans. That's why they're a problem in cities, but not on the open oceans.
- marcosdumay 10y agoAcid rain is much less of a problem on the oceans.
- mikeash 10y agoI'm thinking I care a whole lot more about particulates emitted in the city in which I live than about particulates emitted in the middle of the ocean.
