The article claims that 15 ships pollute as much as all of the worlds cars in terms of co2, but a minute of googling reveals that it’s not the case.. All cars pollute around 3 times more than all ships.
That’s still a lot of pollution from ships, no doubt - but I don’t understand how two different sources can come to such different conclusions.
- mech987 5y agoIf I remember right the pollutants they're talking about are not CO2. The fuel oil that these big ships use is pretty sulfury and dirty and makes a lot of NOx, and that's the sort of stuff that the statistics refer to. They also don't use catalytic converters or some such similar tech. Some environmental coverage likes to omit this level of detail and it makes them sound extra extra horrendous.

- mistrial9 5y agoI was in the engine room of a Maersk line ship, many times while crossing the Pacific. It was like a simple car engine, except the cylinders are each almost 2 meters in diameter. The fuel was raw crude oil with every dirty component, and the force so large, this engine, the size of a two story house, would crush this crude oil to make the combustion. It was pure force, and cheap to run.
