Hamburg to Casablanca freight CO2 emissions

One tonne of cargo shipped Hamburg (DEHAM) to Casablanca (MACAS) by sea emits 27.8 kg CO2e well-to-wake at GLEC v3.2 default factors. The same tonne by air emits 2,031.5 kg — roughly 73x the sea number.

Lane noteEurope-North Africa via Bay of Biscay and Strait of Gibraltar — 5-6 day sailings. Casablanca handles the bulk of Moroccan containerised trade alongside Tanger Med; Renault Tangier exports flow on the backhaul to European factories.

Mode comparison

On the Hamburg to Casablanca 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 (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.
