Karachi to Jebel Ali freight CO2 emissions

One tonne of cargo shipped Karachi (PKKHI) to Jebel Ali (AEJEA) by sea emits 11.3 kg CO2e well-to-wake at GLEC v3.2 default factors. The same tonne by air emits 1,011.5 kg — roughly 90x the sea number.

Lane noteShort Arabian Sea hop — 3-4 day sailings between Karachi Port Trust/Port Qasim and the Jebel Ali transshipment hub. Pakistani textile and rice exports flow predominantly for onward Jebel Ali relay to Europe and East Africa.

Mode comparison

On the Karachi to Jebel Ali lane, air freight emits about 90 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 (850 g CO2e/tkm) and a Container ship 3,000-8,000 TEU (7.5 g CO2e/tkm), partly offset by the shorter great-circle air routing.
