Carbon’s central role in the maritime contract

Sustainability in maritime shipping is no longer just a secondary objective—new and evolving regulations have cemented its place as a central variable in every contract. While the introduction of EU ETS and FuelEU for Maritime marked a turning point for the shipping industry, these regulations do not represent a single moment in time. Instead, they mark the beginning of a new era of continuous compliance and carbon-centric contract management.

As carbon pricing, fuel standards, and reporting mandates continue to expand across regions and voyage types, the most successful organizations won’t be those who simply meet existing regulatory requirements—they’ll be the ones who are ready for the next.

Organizations that embed emissions, exposure, and compliance into their everyday workflows will protect margin and move faster as new frameworks emerge. It’s about much more than adding another layer of reporting—it’s about bringing together environmental and economic intelligence in a single decision infrastructure.

Keep reading to discover what is needed for this new era of carbon-conscious decision making, and how Veson’s unified solutions empower you to address them.


Beyond EU ETS: A trend of rising carbon regulation

EU ETS and FuelEU are just two examples in a trendline of rising carbon regulation around the globe. From early emission standards to the fuel intensity mandates of today, a clear pattern emerges: carbon continues to move closer to the center of commercial shipping contracts, making regulatory agility more important than ever.

Explore the timeline below to see how maritime carbon regulations have evolved since 2000—and how each milestone has pushed the industry towards a more measurable, accountable, and sustainable future.

Carbon Regulation Timeline New

Change in the Industry

Sus 2005

Sus 2006

First IMO GHG Study

Establishes shipping’s share of global CO₂ emissions (~2.7%). 

Sus 2008

MARPOL Annex VI revised

The oil crisis brings skyrocketing fuel prices that trigger route changes, slow steaming, and new vessel designs. 

Sus 2010

EEDI and SEEMP adopted 

First mandatory global CO₂ rules for new and existing ships. 

Sus 2013

Requires CO₂ monitoring, reporting, and verification for voyages touching EU ports. 

Sus 2018

IMO initial GHG strategy 

Sets target to reduce total GHG emissions by 50% by 2050 (from 2008 baseline). 

Sus 2020

IMO 2020 global sulfur cap 

Limits fuel sulfur content to 0.5%, improving air quality and operational efficiency.

Operational and design efficiency ratings become mandatory for all ships.   

Sus 2023

IMO updates GHG strategy 

Commits to net-zero emissions by 2050, with checkpoints in 2030 and 2040.   

Sus 2024

EU ETS extends to maritime 

Carbon pricing applies to CO₂ from vessels ≥5,000 GT operating in the EU.

Sus 2025

FuelEU Maritime enters into force

Sets limits on well-to-wake GHG intensity of fuels and introduces credit trading.

The five pillars of carbon-conscious decision making

Getting ahead of carbon considerations is not just about compliance—it’s about preparation. The ability to proactively integrate each new rule, region, and requirement into your operating system will define how you adapt to the next era of sustainable maritime trade.

Let’s look at the five pillars needed to support carbon-conscious decision making.

Link emissions and economic data within the same decision flow. When carbon considerations are viewed in context with cost, sustainability becomes integral to how the organization views, evaluates, and optimizes performance. 

Integrate carbon thresholds throughout the voyage lifecycle—from planning to settlement—so compliance is continuous, not reactive. By automatically checking each stage of the voyage against EEXI, CII, and FuelEU intensity limits, while managing annual FuelEU compliance pooling, fleet-level performance remains within target as conditions change. 

As new global regulations, operational choices, and counterparty requirements emerge, systems must evolve without disruption. Configurable workflows and data structures make change manageable and measurable.

Combine verified emissions, operational, and financial inputs into one, context-aware source of truth. Data integrity enables accuracy, not just in reporting but also in strategic, carbon-aligned decision-making.

All sides of the contract have a stake in raising the bar for sustainability and reducing barriers to compliance. Connected systems, communication tools, and shared knowledge support cross-ecosystem collaboration and accelerate progress.
