Green shipping corridors have become a key strategic initiative for advancing maritime decarbonization. This study develops an AIS-based bottom–up framework for estimating carbon emissions and compliance costs in green shipping corridors. The framework combines corridor fleet identification, AIS-based energy consumption and emission estimation, and compliance-cost modeling under the IMO CII and GFI requirements. On this basis, eight alternative energy options—HFO, fossil LNG, bio-LNG, e-LNG, bio-methanol, e-methanol, green ammonia, and biofuel B100—together with carbon capture technology, are incorporated into the analysis and applied to the Shanghai–Los Angeles/Long Beach green shipping corridor. The results show that before 2035, the emission reduction requirements of CII can cover the basic compliance requirements of GFI. Without carbon capture, the combined use of fossil LNG and bio-LNG appears to be a relatively favorable transition pathway. When carbon capture is considered, LNG with carbon capture and HFO with carbon capture emerge as two relatively advantageous transition pathways. During 2025–2035, it is recommended that ships first adopt fossil LNG, then gradually introduce limited amounts of bio-LNG, and subsequently integrate carbon capture once the technology becomes mature.
