A trip from Germany to Ireland without using the plane (that actually became a north-west Europe roundtrip)

The Mission:

In Autumn 2019, I set off from Germany to meet a friend in Ireland. As the distance between Germany and Ireland appeared to me too low to justify the usage of the airplane, and the challenge also kind of packed me, I tried to figure out a way to get to Ireland without using the plane, minimize carbon dioxide, and maximize the fun in getting there.

How I got to Ireland and back

As I did not want to got the same way there as back, I decided to approach Ireland from Great-Britain, which itself is easily reachable from Netherlands by Ferry. For getting back, the way should got to France and from there by train back to Germany.

Frankfurt, Germany - Amsterdam/Ijmuiden, Netherlands: High Speed Train ICE, Bus to Ijmuiden

Duration: 4.5 Hrs High Speed Train + 1 Hr Local Train and Bus
CO2 Emissions: Train 450km * 29g/(Person*km) = 13.05kg, Bus Approx. 40km * 83g/(Person*km) = 3.32kg
Total: 16.370kg CO2

Amsterdam/Ijmuiden to Newcastle, England: Ferry "Princess Seaways"

Duration: 15 Hrs CO2 Emissions: 550km * 170g/(Person*km) = 93.5kg CO2

Did this really helped saving carbon dioxide?
