Talk:Initial IMO Strategy on the reduction of GHG emissions from ships

LPG


I'm removing the picture and caption depicting LPG as an alternative fuel because I think it suggests LPG is far more of a solution than it is. According to the DNV source (p. 24), conventional LPG reduces CO2 emissions by 17% relative to heavy fuel oil. This is far from the required emissions decrease of 100%. Renewable LPG has potential, but it's almost certainly not what's depicted, and isn't what "LPG" usually means. The IEA says the most promising low-carbon energy sources for maritime shipping are ammonia, hydrogen, and sustainable biofuels. The UN Emissions Gap report says the same thing, with more emphasis on biofuels and less on hydrogen. Clayoquot (talk &#124; contribs) 22:03, 24 September 2021 (UTC)

Units for emissions intensity
I'm having trouble understanding the following sentence: Emissions intensity (ie. the emissions produced to transport unit goods per unit distance) is targeted to drop 40% by 2030, with the aim of "pursuing efforts towards 70$ by 2050". I'd expect emissions intensity to have units such as "kg of CO2 emitted per ton of goods per km", not a dollar figure. What am I missing?

 * That's a typo my mind apparently skipped over multiple times. The maths for emissions intensity are done in kg(CO2) per kg/tonne (goods) per km in my experience, but I thought the more generic (unit) here would better highlight the meaning behind the term, as the precise units don't matter too much.

 * Ah, perfect. Thanks! Clayoquot (talk &#124; contribs) 04:08, 27 September 2021 (UTC)
