Trade-lane CO₂ emissions

Asia-Europe headhaul deep-sea via Suez. Post-2023 Red Sea Houthi attacks forced most Asia-Europe carriers around the Cape of Good Hope, adding ~3,500 nautical miles per loop and ~25% to per-voyage CO2.

Hamburg is the main North-European hub for German industry inbound. Same Suez/Cape detour applies; the rail option via the China-Europe land bridge is a real but capacity-constrained alternative — about 18 days end-to-end vs 30+ at sea.

Antwerp is the chemical-cluster gateway for Europe; the lane runs alongside Shanghai-Rotterdam on the same vessel rotations. Volume is roughly 60% of the Rotterdam call.

Ningbo is the second-busiest Chinese export gateway after Shanghai; Felixstowe handles ~36% of UK container traffic. Post-Brexit customs friction adds 1-2 days at terminal but does not change the at-sea emissions number.

Alternate UK gateway when Rotterdam transshipment is overflowing — vessels transit Suez and the Strait of Gibraltar before North Sea approach. Post-2023 Red Sea diversions push most calls around the Cape of Good Hope, adding ~3,500 nm per loop.

Trans-Pacific Eastbound — the single highest-volume container lane in the world by TEU. Vessels typically run at 14-16 knots eco-speed; a knot less saves ~7% bunker per voyage.

East-coast service via the Panama Canal; the 2023-24 Panama drought cut daily transit slots from 38 to 22, pushing some Neopanamax sailings around Cape Horn (+8,000 km) or via Suez.

Long Beach sits adjacent to Los Angeles on San Pedro Bay; the two ports together handle ~40% of US containerised imports. Hong Kong volumes shrank sharply post-2019 as Pearl River Delta cargo shifted to Yantian and Nansha.

Shortest of the trans-Pacific container lanes by sea miles. Great-circle routing across the North Pacific gets ships into Puget Sound in 9-11 days at 18 knots; Seattle is a Toyota and Subaru inbound hub.

All-water Panama transit US west-to-east coast — 8,400 km via the Neopanamax locks. Panama drought constrained slots through 2024-2025, pushing some sailings around Cape Horn or to rail-bridge via Los Angeles to Chicago, NY.

Short-sea Pacific coast feeder — 3-4 day sailings hugging the North American west coast. Road and rail are real competitors at ~2,300 km; CN and BNSF intermodal services capture significant tonnage between the two port complexes.

Mature mid-sized lane — typically 7-8 day sailings at 18-19 knots. Vessel sizes are smaller than Asia-Europe (Post-Panamax dominate) because trans-Atlantic volumes do not justify the largest classes.

Charleston runs as the BMW Spartanburg export hub and a major Mercedes import port. Trans-Atlantic vessels here are slightly larger than Rotterdam-NY because of the ro-ro and project-cargo overlap.

Gulf Coast service for the petrochemical complex. Routing crosses the Atlantic then runs through the Florida Straits to Galveston Bay — adds ~2 days vs East Coast calls.

US East Coast to Gulf Coast short-sea — routing via the Florida Straits, 6-7 day sailings. Road and rail are dominant for time-sensitive cargo at ~2,600 km overland; sea wins for project cargo and bulk petrochemicals.

Singapore is the largest transshipment port in the world; most cargo on this lane is feeder relay for onward Asia-Europe or Asia-North America voyages. Roughly 7-9 day sailings.

Short intra-Asia lane — typically 3-day sailings. Busan acts as the main Korean transshipment hub; semiconductor and EV-battery cargo runs predominantly air freight rather than ocean.

Japan-Philippines feeder volume runs mostly for the Toyota and Honda parts pipelines; 4-5 day sailings. Manila North Harbor congestion adds 1-2 days at berth.

Japan-Southeast Asia trunk — 7-8 day sailings transiting the East China Sea and South China Sea before approaching Singapore Strait. Heavy electronics and Toyota/Honda parts flow; Singapore handles onward transshipment to South Asia and Europe.

Short intra-Asia China-Philippines run — 3-4 day sailings across the South China Sea. Manila North Harbor congestion typically adds 1-2 days at berth and pushes some carriers to call Subic Bay as a relief port.

Singapore Strait feeder to Tanjung Priok — 36-48 hour sailings across the Singapore Strait and Java Sea. Singapore handles roughly 80% of Indonesian transshipment cargo; the lane runs as a dense feeder loop with daily departures.

India-Southeast Asia trunk via Nhava Sheva (JNPT) — transits the Arabian Sea and Malacca Strait. Singapore acts as the relay hub for onward East Asia and Trans-Pacific routes; 8-10 day sailings on the direct service.

Gulf-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.

The hop that every Asia-Europe container vessel makes before clearing the canal. Suez northbound transit dues alone run ~USD 700,000 for a fully laden ULCV; the slow steaming on this approach trims fuel by 8-12%.

Major 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.

Arabian Sea crossing — 4-5 day sailings across one of the densest sub-regional trade lanes. Indian textile, jewellery, and food exports dominate the eastbound leg; the corridor is also a major air-freight corridor on the Mumbai-Dubai shuttle pattern.

Short 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.

Asia to Red Sea gateway via Malacca and Bab-el-Mandeb — Jeddah Islamic Port is the largest Saudi container facility. Houthi attacks have pushed some carriers to call Jeddah only via Suez southbound after Med calls rather than direct from Asia.

Gulf-North Europe routing transits Hormuz, Bab-el-Mandeb, and Suez before North Sea approach — Cape detour during Red Sea disruption adds ~5,000 km. Hamburg handles the bulk of UAE petrochemical and aluminium-into-Germany flows.

South Atlantic crossing — 14-16 days at sea. A meaningful share of this lane is reefer (coffee, beef), which adds 12-18% to the per-tkm CO2 vs dry containers because of compressor running on bunker generators.

River Plate to North Europe — service typically calls at Montevideo and Rio Grande en route. Bulk soybean volumes dwarf containerised cargo by tonnage; the lane carries ~14% of Argentina-EU trade.

Deep-water trans-equatorial Atlantic crossing — 14-16 day sailings between Northern Europe and the São Paulo gateway. Eurobrazil headhaul carries strong fertiliser and machinery flows; backhaul is coffee, orange juice, and refrigerated meat.

Northern Europe to River Plate — deep-water trans-equatorial Atlantic with typical Montevideo or Rio Grande stop en route. 16-18 day sailings; Buenos Aires River Plate access is depth-constrained, capping vessel size on this lane.

Trans-equatorial Atlantic to southern Brazil — Itajaí/Navegantes complex serves the Santa Catarina industrial belt. 14-16 day sailings; reefer share is notable on the backhaul for frozen poultry and citrus.

Durban is the largest African container port. Citrus season (June-October) pushes reefer volume to 40% of containerised exports; the lane runs around the West African coast and saves no distance via Suez.

East African gateway to North Europe via Suez (or Cape during Red Sea disruptions). Mombasa horticulture exports run a significant air-cargo share — Kenyan cut flowers reach UK supermarkets in 24-36 hours by air.

Asia-Southern Africa trunk transits the Malacca Strait and Indian Ocean before South African approach — 22-24 day sailings. Durban is the largest African container port; Chinese machinery and automotive parts dominate the headhaul.

Asia-West Africa — typically routed via the Cape of Good Hope rather than Suez given the Nigerian destination, 28-30 day sailings. Apapa and Tin Can Island container terminals serve Lagos; berth congestion adds 5-10 days at port.

Asia-East Africa via the Indian Ocean — direct great-circle crossing without Suez. Singapore acts as the consolidation hub for cargo originating across East Asia bound for Kenya, Uganda, and Tanzania (via Mombasa hinterland rail).

Europe-West Africa trunk down the Atlantic coast via Bay of Biscay and Gulf of Guinea — 12-14 day sailings. Apapa congestion frequently pushes effective transit time well beyond at-sea numbers; chronic berth waits run to a week.

Europe-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.

Northern Europe to the Cape via West African coast — 16-18 day sailings. Cape Town Container Terminal is wind-exposed and frequently shuts on south-easterly gusts; the backhaul carries deciduous fruit, wine, and Western Cape citrus.

Africa intra trunk around the Cape of Good Hope — 10-12 day sailings between the continent's two largest container gateways. Intra-African containerised trade remains thin relative to Asia/Europe flows; most cargo here is South African industry into Nigeria.

Northern-to-Southern Europe lane — sea via Gibraltar is the bulk option but road and rail are real competitors at ~2,300 km overland. Rail electrification across the Brenner makes the train ~80% lower CO2 than the truck on this corridor.

Rhine-Alpine corridor — the EU Combined Transport network targets a modal shift to rail on this route. Road still dominates on volume but rail captures roughly 18% of containerised tonnage.

South Pacific great-circle crossing — typically 17-19 days at sea. Australian beef and wine exports drive reefer demand; the lane runs at lower fill rates than trans-Pacific so per-tkm emissions are 15-20% higher than Shanghai-LA.

Backbone of the Asia-Pacific bulk trade. Capesize iron-ore bulkers running Port Hedland/Dampier-Qingdao dominate by tonnage; the containerised dairy and wool segment shown here is a fraction of total cargo on this corridor.

FedEx World Hub at Memphis handles ~180 daily wide-body cargo movements; Hong Kong is one of its top three origin pairs by tonnage. This is the canonical lane for justifying air freight on time-sensitive electronics and pharma.

FRA-ORD is the canonical trans-Atlantic air-freight pair — Lufthansa Cargo and ABC operate dedicated 777F and MD-11F services into Chicago O'Hare. German pharma and automotive parts dominate the westbound leg.

Anchorage Ted Stevens is the major trans-Pacific air-cargo refuelling and crew-change stop — FedEx and UPS operate huge tech-stop volumes en route from Asia to US lower-48 hubs. The HKG-ANC segment alone moves over 1 million tonnes of air cargo annually.
