>>>Impressive. Specially when I know that most of the cable bundles are prepared here, in a german-owned sweatshop.

The issue will be that where labour used to be a huge part of cost, robotic costs ought to be similar wherever you are- meaning transport becomes a bigger concern. Not just for cost: some observers claim that 6 container ships burning bunker oil can produce more greenhouse gas than all the motor vehicles on the planet. You can imagine the pressures not to buy goods tainted with that. Effect on industry? Who can say, but probably "buy made at home" will become much more prevalent if it avoids risking the planet, not just blue collar workers...

Embolded seems like pure BS. Greenhouse gas is mostly Carbondioxide, which will be emitted according to the energy "packed" into the fuel in question (Diesel, Gasoline, the special "Car Gas" LPG sold at least in the Netherlands and here, Natural Gas, Hydrogen listed only as Carbon-free exemption...) and the amount burned.
There are some gases, mostly used in heat pumps like fridges and air conditioning, which can introduce unwanted effects in the atmosphere like the famous Ozon-hole in Southern hemisphere. Does NOT apply to container Diesel engines.
Then there are other noxic/toxic emissions: currently NOx the banner child to argue for Diesel banning in inner cities, last century lead additions to gasoline. Diesel engines with their low frequeny of burns never had the lead problem, but ship diesels as they are unregulated produce lots of other unwanted chemical residues - which is lousy for any port or river city. On the ocean probably no environmental hazard and population density affected often not a problem - unless strong tail winds blow exhausts over a cruise ship.
Minuscle particles: those happen more frequently in car engines trimmed for fuel economy, but can be effectively eliminated via exhaust systems (some new Diesel engines really "clean" the air as their exhaust has less minuscle particles than the air of "dirty" larger cities) but also when burning wood or braking with traditional (read: non-recuperating electric) brakes or just using tires to move...
