GHG Emissions API

Use NavAPI's Voyage Metrics API for analysing a sea voyage, making voyage estimations, Our Voyage Metrics calculates voyage times at sea, fuel usage per voyage leg, reporting bunker consumption, CO₂e, and g/TW. Time spent at ports is included, delivering accurate voyage data. Achieve clarity in cost, compliance, and operational efficiency—all in one easy call.

GHG Emissions API Features

Unlimited Voyage Metrics Bundle

For a subscription starting at €6,900/year, enjoy unlimited usage of our GHG Emissions API with no per-call fees. Evaluate carbon footprints, fuel consumption, compliance, route comparisons, and heavy-load reporting as often as needed—ideal for analytics, real-time monitoring, or continuous audits. Build your applications around emission insights, reduce costs, and align with environmental goals using data-driven calculations.

Voyage Consumptions Breakdown

Get a detailed breakdown of total fuel oil (FO) and gas oil (GO) consumption for your entire voyage, with separate tallies for SECA and non-SECA usage. Our GHG Emissions API calculates every segment’s ongoing FO and GO requirements based on route choices, speeds, port times, and operational conditions like idle or laden states and weather delays, delivering clear insight into your vessel’s overall fuel costs, compliance alignment, and emission impact.

Voyage Time Breakdown

Get a complete breakdown of each voyage’s time, with distinct figures for sea travel and port stays, measured in days and hours. Our GHG Emissions API details exact at-sea durations and total port time, culminating in a full voyage total. This clarity facilitates precise scheduling, resource allocation, and cost estimations, ensuring every segment of the trip is accounted for and optimally managed—even during idle periods or unexpected delays.

Fully Customisable Routes

Although focused on calculating greenhouse gas emissions, our GHG Emissions API fully accommodates the advanced navigation parameters of our Sea Routing API—such as canal avoidance, ASL compliance, speed variations, or SECA settings. By reflecting real-world routing conditions, this synergy delivers precise consumption and emissions figures, ensuring the CO2 calculations remain accurate and aligned with real world navigation.

Energy Based Metrics

Obtain comprehensive, reporting-ready metrics—total bunkers consumed, CO₂e in metric tons, g/TW, and more—for use in emissions compliance, verifying vessel data, or identifying greener routes and vessels. Our GHG Emissions API consolidates all this information into one response, making it easy to spot discrepancies, compare environmental performance, and maintain clarity in your emissions records across operations.

Port Days and Weather Delays

Account for exact days at port—idle or laden—and at sea, incorporating weather delays that extend travel. Our GHG Emissions API factors each segment’s duration and condition into consumption and CO₂ calculations, reflecting real-world shipping practices. This ensures a realistic overview of how operational variances, like prolonged port stays and weather disruptions, affect overall fuel usage and emissions.
