A low-cost digital solution is having an outsized impact on carbon emissions.
The Ports of Los Angeles and Long Beach in California have adopted a vessel queuing system, similar to OpenTable’s reservation model, to manage incoming ships. This has not only eased port congestion at a relatively low cost but also enabled global shipping companies to cut emissions by more than 20%. And the system was developed and launched in under a month.
Ports introduce queueing system to predict arrival times
A study from the Benioff Ocean Science Laboratory at the University of California, Santa Barbara, revealed that the queuing system, introduced in 2021 at Southern California’s busiest ports, reduced emissions on trans-Pacific shipping routes by up to 24%.
