The maritime emissions regulatory landscape is expanding fast. The Siglar Carbon Scheme Navigator puts the full picture in one place, expert-reviewed and free to use.
Maritime emissions regulation has never been more complex, or more commercially consequential. In the space of just a few years, the industry has moved from a single global reporting framework to a layered, overlapping set of schemes: the EU ETS, FuelEU Maritime, the UK ETS, CII, the IMO Net-Zero Framework, and a growing number of sovereign carbon initiatives from individual port states. Each scheme works differently. Each affects different actors in the value chain, on different routes, in different ways.
The challenge is not a shortage of information. It is a shortage of reliable information. In a world where anyone can ask an AI for a regulatory summary, and get a confident, plausible, and occasionally wrong answer, the industry needs a source it can trust. The Siglar Carbon Scheme Navigator is that source: expert-reviewed, built from primary regulatory documents, and updated as the landscape changes.
The Scheme Navigator is a free, interactive overview of every maritime emissions regulation with a direct and substantial commercial impact on the shipping value chain. It maps both implemented schemes and schemes under development, giving users a single, structured starting point to understand the regulatory landscape, without needing to read through hundreds of pages of IMO circulars, EU legislation and national frameworks to get there.
It is not a compliance tool. It is not a vessel tracking system. It does not show where emissions come from on a map. It shows which regulations exist, where they apply, who they affect, and, critically, what they cost.
The Scheme Navigator launches with the schemes we believe matter most commercially right now. But the regulatory landscape will keep expanding, and so will the Navigator.
As new schemes emerge and existing ones develop, we will add them to the map. We also want to hear from users about what they would find most useful to see next, whether that is additional schemes, new geographies, or different ways of presenting the information.
If you have a view on what should be on the map, or what would make it more useful for your work, we would like to hear it. Tell us what you want to see →
The Scheme Navigator is intended for anyone in the maritime value chain who needs to understand the regulatory landscape, whether you are encountering these schemes for the first time or looking to verify your existing understanding against a quality-assured source:
• Charterers - assess the combined regulatory cost exposure of your trade lanes and charter structures before it shows up on your P&L
• Ship owners and operators - Map compliance obligations across your fleet, flag states and trading patterns.
• Brokers - become the person in the room who can explain what the regulations mean commercially, not just that they exist
• Commodity traders - factor the full regulatory cost into your trading decisions, and understand how scheme costs flow through the charter party
• Ship finance - understand the regulatory environment affecting the assets that you finance
• Ports and technical managers - understand how the regulatory environment affects the fleet you manage, and what your responsibilities are under each scheme
The Navigator gives you the lay of the land. It is a structured starting point to understand the industry, assess your exposure, and move one step closer to more informed decisions. It is designed to support awareness, learning and early-stage assessment of maritime environmental compliance exposure, not to replace route-level cost modelling, fleet compliance management or regulatory risk assessment on specific voyages.
For users who reach the edge of what the Navigator can tell them, Siglar's platform and advisory services pick up from there.
The Siglar Carbon Scheme Navigator is free to use and requires no registration.
