Huawei's own case study confirms: 'A major milestone came in October 2021, when Tianjin launched the world's first Smart Zero-Carbon Terminal.'",
      "caveat": "The State Council link cited in this entry now redirects to the gov.cn homepage instead of the article; the date and wording above come from an identically titled China Daily republish ('Tianjin Port reveals world's first zero carbon terminal', dated Nov 24, 2021) and are corroborated independently by Huawei's own account of the October 2021 launch.",

It describes the terminal's transport robots (ARTs) as using cameras, radar and BeiDou satellite positioning to navigate on their own, eliminating the need to recruit truck drivers ('ARTs, by contrast, work around the clock ... deploying ARTs eliminates the need for road reconstruction'), and separately confirms cranes are moved to remote control: 'A single operator can remotely control multiple quay cranes simultaneously.'",
      "caveat": "Huawei's own account never uses the classification 'Level 4' or 'L4' anywhere on the page for the transport robots; it describes them only as an 'autonomous driving system.' The same page also lists 'container truck drivers' among the staff at the terminal's control center alongside crane operators, without clarifying whether that refers to standby/dispatch roles or active on-board drivers.",

      "caveat": "Neither cited source uses the words 'storage' or 'microgrid,' and neither explicitly says the generation is 'on-site' — they confirm wind-and-solar power and describe the terminal as fully self-powered, but not the battery-storage component or grid architecture this passage names.
