Singapore to Jebel Ali freight CO2 emissions

One tonne of cargo shipped Singapore (SGSIN) to Jebel Ali (AEJEA) by sea emits 48.8 kg CO2e well-to-wake at GLEC v3.2 default factors. The same tonne by air emits 3,550.7 kg — roughly 73x the sea number.

Lane noteMajor Asia-Gulf trunk — transits the Malacca Strait, Indian Ocean, and Strait of Hormuz before entering the Persian Gulf. Roughly 11-13 day sailings; both ports are top-five transshipment hubs globally, so feeder onward flow is substantial.

Mode comparison

On the Singapore to Jebel Ali lane, air freight emits about 73 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 8,000+ TEU (7.5 g CO2e/tkm), partly offset by the shorter great-circle air routing.
