The Port of San Diego has selected PortXchange‘s EmissionInsider platform for its Blue Economy Incubator programme, adding a 14th project to an initiative that has backed sustainable, ocean-based technology across the San Diego region since 2016. The Board of Port Commissioners approved the agreement on 23 June 2026, positioning EmissionInsider as a pilot tool to help the Port inventory emissions in support of its Maritime Clean Air Strategy. The Rotterdam-based maritime technology company will work with the Port to collect, integrate, analyse and report emissions data across operations it does not directly control, including shipping activity. The partnership arrives as ports across the United States face growing pressure to back climate commitments with measurable, verifiable data.

A Pilot Built On Data, Not Just Ambition

The rationale behind the pilot rests on a distinction that PortXchange draws sharply: setting decarbonisation targets is one thing, but reducing emissions in practice depends on operational visibility. Ports often have limited direct control over ships, trucks and rail activity moving through their terminals, which makes accurate measurement difficult and improvement harder to prioritise. EmissionInsider was built to close that gap, giving port authorities a clearer picture of where emissions originate, where bottlenecks slow progress, and where interventions would have the most effect.

For the Port of San Diego, the platform is expected to feed directly into future planning, reporting and environmental decision-making, adding a data layer to a strategy that has already set out ambitious clean air goals.

Recognising A Port’s Environmental Track Record

PortXchange has framed the agreement as recognition of the Port of San Diego’s standing among US ports on environmental matters, describing the relationship as one built on shared priorities rather than a straightforward vendor arrangement.

Sjoerd de Jager, PortXchange Co-Founder and Managing Director, said:

“We are truly proud to partner with the Port of San Diego, a port that has long set the standard for environmental leadership in the United States.”

Sjoerd de Jager, PortXchange Co-Founder and Managing Director, added:

“Decarbonization is the defining challenge of our time, and moments like these remind us why we do what we do. With EmissionInsider, we’re helping ports better understand emissions from ships and other outside operations they don’t directly control, so they can take informed action to reduce air pollution and advance decarbonization. This is exactly the kind of partnership that moves the maritime industry forward.”

From Reporting Tool To Wider Platform

EmissionInsider forms the core of a broader PortXchange offering that spans Scope 1, 2 and 3 emissions monitoring across ship, truck, rail and terminal activity, alongside a standalone Port Emissions Reporter designed to convert raw emissions data into regulatory-ready reporting. The company also runs Synchronizer, a Just-in-Time planning tool aimed at cutting vessel idle time by coordinating ships, terminals and service providers more closely.

Beyond its core platforms, PortXchange builds custom digital solutions tailored to the specific workflows of ports, terminals and inland operators, integrating through existing APIs rather than imposing generic tools. One such product, ETAPredictor, uses an AI-based engine to continuously recalculate vessel arrival times from real-time operational data. Originally built for a large inland barge operator managing thousands of vessels, it replaced static ETA estimates with dynamic predictions that improved planning accuracy and asset utilisation.

Accountability As The Next Standard

PortXchange positions the San Diego agreement as evidence of a shift already underway across the maritime sector, one where environmental credibility depends less on the scale of a strategy and more on the operational decisions that follow it. As regulatory scrutiny increases, the company argues, ports will be judged on the quality and reliability of their emissions data as much as the ambition of their targets. As a B Corp certified company, PortXchange presents its role as helping ports move past data paralysis toward measurable accountability, a proposition the Port of San Diego pilot will now begin to test in practice.
