Fig. 4: Projected regional shipping carbon emissions by ship type under three decarbonization strategies.
From: Arctic Sea Route access reshapes global shipping carbon emissions
Spatial projections of emission intensity (Mt CO2eq km⁻²) from 2025 to 2100 under a the IMO 2023 Strategy, b the Green Corridor Strategy, and c the Net-Zero Strategy across six major sea regions, namely, the Arctic, the Caribbean Sea, the Singapore Strait, the North Pacific Ocean, the North Atlantic Ocean, and the South China Sea. Each subplot shows emissions disaggregated by ship type: container, bulk, chemical, gas, and oil. d Sectoral distribution of projected carbon emissions along key green shipping corridors from 2025 to 2050.
