In ports around the world, terabytes of emissions data are sitting idle. Not because the data doesn’t exist, but because we’ve convinced ourselves that it’s not “perfect” enough to act on.
At PortXchange, we’ve been clear and direct about this: Ports already have more than enough data to start decarbonizing. What’s missing isn’t precision; it’s the courage to go from spreadsheet paralysis to strategic action.
Our recent industry poll confirmed what we’ve long suspected. When asked, “What’s the biggest barrier to using emissions data to drive real action in ports?”, the majority of respondents pointed to two culprits:
- Data stuck in silos
- No business incentive
Both are solvable problems. But they require a mindset shift: moving from treating emissions data as an academic exercise to using it as a decision-making engine.
The Comfort of the Data Debate
Right now, too many sustainability strategies are stalling in what we call spreadsheet paralysis. Perfecting decimal points has become a convenient excuse to avoid tough operational decisions.
Meanwhile, the climate clock is ticking. Every day of hesitation is a day of avoidable emissions.
Yes, some ports have made progress on Scope 1 and 2 through electrification, renewables and energy-efficient upgrades. But in many cases, the elephant in the room remains Scope 3, which comes from vessel activity, terminal operations and hinterland logistics.
If your port is installing solar panels while tripling cruise traffic, you’re not decarbonizing, you’re greenwashing.
From Reporting to Reduction
At PortXchange, our focus has always been working with ports to drive real, measurable change. Our roots are in maritime, port, and shipping operations, and today that legacy powers our flagship platform: EmissionInsider.
EmissionInsider and our Port Emissions Report don’t just measure emissions; they show exactly where reductions can be made, now.
- Spot patterns, not just spikes. Long-term trends, like average idle times at berth, often reveal far bigger reduction opportunities than reacting to short-term anomalies.
- Connect the dots. By integrating datasets across ships, terminals, trucks and rail, we provide every stakeholder, including terminal operators, shipping lines, and service providers, with the same emissions reality.
- Turn maps into action. Our clear, visual hotspot analysis makes it easy for decision-makers to see the problem and act with confidence.
And when ports need to share their progress, the Port Emissions Report turns complex datasets into public-friendly insights for communities and boards, transforming transparency into trust.
Designed for How Ports Actually Work
Ports don’t have the luxury of rebuilding their tech stack just to decarbonize. That’s why EmissionInsider is modular, API-first, and system-agnostic. We integrate with existing systems, enabling quick connections and helping ports maximize the value of their existing data.
It’s a shift from static reporting to live emissions intelligence, the kind that allows port teams to make operational decisions in the moment, not months later.
Built on Credible, Industry-Standard Methods
We know credibility matters. That’s why our calculations follow recognized, industry-standard methodologies, including:
- The IMO’s guidelines
- GHG Protocol
- TNO’s models in Europe
- The EPA’s MOVES5 framework in the US
These aren’t just numbers on a chart; they’re regulation-ready outputs that ports can use for compliance, strategy, and investor reporting.
Ports don’t need another data debate. They need clear, trusted intelligence that shows where to act and how to deliver measurable results. That’s exactly what EmissionInsider was built to do.
The Ports That Will Lead This Decade
The leaders of this decade won’t be the ports that waited for hydrogen or synthetic fuels to arrive. They’ll be the ones who made bold, sometimes uncomfortable operational changes based on the emissions insight they already had.
Belfast Harbour: Proof That Action Beats Perfection
For the past two years, 2023 and 2024, Belfast Harbour has invested in building a complete picture of its emissions. As part of this initiative, they purchased our standalone Port Emissions Report, which provided a detailed analysis of in-port vessel emissions. These fall within Scope 3, an often-overlooked area that, while not mandatory to report, represents a significant share of a port’s overall impact.
In-port vessel emissions cover ocean-going ships entering and operating within port limits. While the Harbour does not directly control these operations, tracking them is essential for transparency and for preparing for the transition to new fuels and future regulatory requirements. Emissions coming from vessels account for 95+% of all port-related emissions.
In 2024, in-port vessel emissions were calculated at 99,189 tCO₂e, covering the Victoria Channel up to the port limits. These figures were modelled using AIS (Automatic Identification System) data, engine and fuel profiles, and activity-based emissions factors aligned with the IMO GHG Frameworks and validated by TNO, the leading Dutch research institute.
Our Port Emissions Report gave Belfast Harbour the ability to monitor and understand a major part of their Scope 3 emissions in-port vessel activity, which would have been far harder to achieve on their own. That visibility is helping them extend beyond Scope 1 and 2 into the larger, harder-to-tackle emissions they don’t directly control.
The lesson is clear: waiting for perfect Scope 3 data is a missed opportunity. Belfast Harbour demonstrates that acting on credible insights today rather than debating data tomorrow drives measurable progress on the emissions that matter most.
Decarbonization Demands More Than Data
And yes, this takes more than technology. It takes leadership willing to:
- Break down data silos
- Align incentives between commercial and environmental goals
- Act on the “known knowns” rather than hiding behind “unknown unknowns”
Sjoerd de Jager, our Managing Director & Co-Founder, sums it up: “We’re not here to criticize from the sidelines. We’re here to partner with ports that are serious about cutting emissions, not tomorrow, but today, with proven, implementation-ready green technology that turns existing emissions data into measurable reductions.”
The era of collecting emissions data without acting on it is over. If your port is ready to move beyond reports and start delivering measurable reductions, let’s make it happen.
