We have for the past 13 years, regularly analysed the online carbon emissions calculators provided by the ocean carriers. And over the years, we have shown significant discrepancy between the results provided by these calculators. We did this exercise once again, focusing on Ocean Alliance, as all member carriers have publicly available carbon calculators. We specifically looked at shipping 1 TEU on Shanghai-Rotterdam. In the case of CMA CGM, they include results for 3 of the 5 Ocean Alliance services, as the remaining 2 serve Rotterdam-Shanghai on the backhaul due to the routing sequence. Evergreen and OOCL provide a measure for all 5 services, with OOCL also including their non-alliance LLX service. COSCO only provides a single measurement, for their AEU3 service. (....)
