Yeah, there's a ferry from Rostock to Helsinki. However I'm trying to reduce my travel-related emissions, and after crunching the numbers have concluded that the best option would be ferry+train via Sweden, with electric car via Sweden a close second (per head, assuming two people or more in the car). Fingers crossed for that tunnel and a direct overnight train connection!

In terms of emissions how does that compare to flying?

[lordnacho]

How did you work out the emissions of the ferry routes?

[aakour]

I used the numbers from the Finnish state research centre VTT (http://lipasto.vtt.fi/yksikkopaastot/tavaraliikennee/vesilii...)

Looks like a useful table, but unless I've missed it you need to know how many people/cars are on each ship?

[aakour]

My understanding is that these numbers (try to) account for actual real world usage rates. Actual emissions will of course depend on a whole lot of things, including the things you mentioned, prevailing winds, etc. Same for estimating grid emissions for charging the car of course - the exact mix of sources is always in flux.

Where are the car trains when you need them!
