Isn't the problem that ships are burning heavy oil instead of diesel or similar? CO2 isn't the main worry afaik, it's the rest that gets blasted unfiltered into the atmosphere and the left over sludge that gets illegally dumped into the sea.
- azepoi 6y agoit's not perfect but it's gotten better apparently. 170 countries have signed a treaty significantly reducing the fuel sulphur content. https://en.wikipedia.org/wiki/MARPOL_73/78#IMO_2020 https://en.wikipedia.org/wiki/MARPOL_73/78#IMO_2020 https://www.imo.org/fr/MediaCentre/HotTopics/Pages/Sulphur-2020.aspx https://www.imo.org/fr/MediaCentre/HotTopics/Pages/Sulphur-2... https://www.imo.org/en/MediaCentre/PressBriefings/pages/02-IMO-2020.aspx https://www.imo.org/en/MediaCentre/PressBriefings/pages/02-I... The upper limit of the sulphur content of ships' fuel oil was reduced to 0.5% (from 3.5% previously) - under the so-called "IMO 2020" regulation prescribed in the MARPOL Convention. This significantly reduces the amount of sulphur oxide emanating from ships.
- epja 6y agoIronically, a reduction in sulfur emitted from these ships may actually accelerate global warming: https://www.technologyreview.com/2018/01/22/67402/were-about-to-kill-a-massive-accidental-experiment-in-halting-global-warming/ https://www.technologyreview.com/2018/01/22/67402/were-about...
- lmm 6y agoBurning that kind of fuel near populated areas is a problem, so long-distance shipping is probably the best use for it.
