How green is your ferry?

"How green is your ferry?" is the question and you might be pleased to know that, this time, I am, providing part of the answer.

The question is not directed at the ferry operators of course because they know, but more so at anyone being involved in the transportation,trucking or logistics industry.

The number of LNG / bio LNG trucks on our roads is increasing and smart TMS's help reduce unnecessary fuel burn.

So far, so good. But what happens to the CO2 footprint when a ferryleg is included in the transport? I know that many major shippers want to have the total CO2 emissions of a journey reported but do you then know where to look?

Which ferry operator runs the greenest ferries in what geography and on what routes?

And then: Is 'hybrid' always 'green' or is LNG better? What does 'hybrid' actually mean?

There are many nuances to the theme: Hybrid can mean that a ferry is able to operate on battery power on an entire crossing, in port and when entering / exiting the port or just when manouvring in the port (the latter not being insignifcant though). There's hybrid and then there's, well, different hybrid.

'Hybrid' what? LNG / battery or diesel / battery?

What about 'dual fuel' then? When a ship can run on diesel / oil (don't get me started on the different oils...) or LNG. *Can* be run is the key here. So, is the ship then *actually* run more on LNG or diesel ? If on LNG then mostly bio LNG?

I could go on but you get the drift. It's not black and white.

So, what green ferries operate in the North sea, the Baltic sea, the bay of Biscay and the Irish sea?

One more thing: If you look for 100% battery powered for a 3hour 45 minute crossing you need to look at the South Atlantic from 2025.
