Jebel Ali to Rotterdam freight CO2 emissions
One tonne of cargo shipped Jebel Ali (AEJEA) to Rotterdam (NLRTM) by sea emits 64.9 kg CO2e well-to-wake at GLEC v3.2 default factors. The same tonne by air emits 3,222.4 kg — roughly 50x the sea number.
Lane noteGulf-Europe routing via Suez. Jebel Ali is the largest Middle-East container hub; the lane gained a Cape detour during Red Sea disruptions, adding ~5,000 km to the sea leg.

Mode comparison
On the Jebel Ali to Rotterdam lane, air freight emits about 50 times more CO2e per tonne than sea freight at GLEC v3.2 defaults. The gap is driven by the WTW factor difference between long-haul belly cargo (608 g CO2e/tkm) and a Container ship 10,000-15,000 TEU (5.5 g CO2e/tkm), partly offset by the shorter great-circle air routing.
