Carriers send shippers a single arrival time and leave them to discover how reliable it is. A forecast should arrive with a window, a published record of how often that window holds, and a trace of every occasion someone overrode it.

Shippers reporting transport emissions are often given a factor-based figure for the loaded voyage alone. Carriers that can measure fuel should report what was burnt, allocate the empty return by a published rule and show the uncertainty, even when the result is less flattering.
Carriers often refuse shippers data that is already public while letting slip, through informal channels, data that reveals other customers' business. Data-sharing should be designed around what a shipper could infer, not around which tables feel sensitive.
