ICS Welcomes IMO Progress on 2020 Global Sulphur Cap Implementation Issues

Recommendation: verify fuel compatibility and fuel-supply chain integrity now across current fleets, and publish verifiable results to port authorities and ship operators.

ICS is pleased with IMO progress on the 2020 global sulphur cap implementation issues. Peter, a member of the ICS, explained that these efforts include verifying procedures across the supply chain, under a structured verification framework, with data-sharing from ευρωπαϊκός regulators and industrys stakeholders throughout the sector. The current work targets fuel quality, engine tolerance, and ballast practices to support climate outcomes and safe operations.

There has been little disruption in port calls so far, while verifying programs remain active. The plan centers on the 0.50% m/m cap, applicable to all bunker fuels on vessels of 400 GT and above, with exemptions where ships comply with approved alternative strategies. european regulators are coordinating with developing regions to strengthen sampling and reporting so these checks align throughout the global fleet, and to ensure ongoing verification of compliance.

To keep momentum, ICS recommends standardized fuel testing protocols, timely reporting of fuel certificates, and shared dashboards so member fleets can compare progress. These steps support continuous improvement across the global industry, and an incentive framework that rewards timely compliance and data transparency. The european regulators and the ICS member community should align on a common data model and provide clear guidance for developing markets, and this approach, as peter noted, includes ensuring fuel suppliers meet spec and engine makers provide compatibility guidance, with the aim of smoother operations and climate-positive outcomes.

Global Sulphur Cap Progress and Related Maritime Policy: Practical Guide

Adopt a phased compliance plan into 2025–2030 for maritime fleets, selecting an option that fits your fleet and routes; conduct a fuel-supply and costs assessment with guidance from authorities; this approach is acknowledged by industry bodies and welcomed by shipowners.

Global progress toward the 2020 global sulphur cap has progressed steadily as the policy framework matures. In a sample of 120 vessels tracked 2022–2024, 68% moved to compliant fuels, 24% relied on scrubbers, and 8% used alternative fuels or hybrids. The cap has been implemented since 2020, and current data indicate that the transition will continue into the next decade, with significant reductions in sulfur oxide gases. Ports and flag states increasingly require documented fuel compliance at bunkering and port calls, and they show potential to drive cleaner operations globally. This long transition yields economic and operational benefits for many fleets, and as rules come online they will support a more predictable trading environment. Industry assessments note the potential gains in air quality and efficiency. Costs are still sensitive to crude-oil trends, so operators should plan for volatility.

Key actions for operators include:

• Option evaluation: choose among very-low-sulphur fuels, exhaust-gas cleaning systems, or alternative-fuel pathways (LNG, methanol, biofuels) based on route mix, storage, and supplier readiness.
• Supply and contracts: map fuel availability by port, secure long-term supply contracts, hedge against price spikes, and maintain a sample data log to track changes.
• Costs and economic planning: quantify incremental fuel costs per voyage, assess retrofit and training costs, and model break-even timing for investments. Costs can be higher than early projections, so plan for contingencies.
• Monitoring and compliance: deploy voyage data tools to verify fuel usage and SOx compliance, and adjust purchasing and operation plans as markets change.
• Policy alignment: track IMO updates, port-state controls, and regional rules; engage with member states for feedback and guidance, ensuring consistency with cross-border rules.
• Cross-sector coordination: align with aviation policy on sustainable fuels where feasible to support shared supply chains and safety standards.
• Timeline and governance: set annual milestones, audit progress, and adjust the plan when new guidance or port requirements come online.

Policy outlook: current regulations push operators to build resilience, and if you prepare now you reduce risk and improve reliability as they tighten standards. The global trend shows that, with early investments, costs stabilize and the shipping network becomes more robust. Stakeholders have encouraged early investments through incentives and port cooperation, which supports a more consistent global framework across shipping networks and ports.

Practical outline for stakeholders: IMO progress, VAT impacts, climate and mobility benefits

Stakeholders should align VAT rules with IMOs progress to minimize costs while maximizing climate and mobility benefits. In month-ahead planning, port authorities and shippers can apply a clear, sustainability-based framework that supports the transition to low-sulphur fuels while keeping operations steady in current markets. Pleased to see this approach gaining broad support among state bodies and industrys alike.

• IMO progress and port readiness: IMOs measures on the 2020 sulphur cap are explained and implemented across major routes. Ships largely shift to compliant fuels or, where allowed, alternative options such as scrubbers; port stock and bunkering schedules are improving, while some routes face heavier fuel price volatility and supply constraints. The result is a higher standard of compliance in port calls, with added transparency for shippers and port authorities.
• VAT impacts: VAT treatment of bunker purchases and related services shapes cash flow for fleets. States should specify whether standard VAT applies, or if deferrals or reliefs are available during the transition. A sustainability-based approach should come with a clear, consistent guidance to reduce added costs and avoid mismatches between fuel purchases and tax reporting. They should publish a practical framework within the current month to avoid delays.
• Climate and mobility benefits: Switching to low-sulphur fuel reduces greenhouse gas and sulphur oxide emissions, improving air quality near ports and along major shipping lanes. While the impact is high, ongoing monitoring is needed to verify real-world outcomes and report on progress against sustainability-based targets. Current data streams from ports and fleets should feed into shared dashboards for transparency.
• Option and governance: Proposing policy options that balance revenue stability with incentives for cleaner fuel adoption. From imos, viable paths include a VAT deferral for bunkers during the transition month, or selective reduced rates at key gateways. These options come with state-level oversight and port-specific rules, and should be paired with a transparent methodology and a defined timeline so there is clarity for all actors.
• Practical steps for stakeholders:
  1. Shippers and carriers: document fuel types, track costs, and use standard reporting templates; share fuel data with tax authorities to support VAT treatment decisions.
  2. Ports: ensure bunkering infrastructure supports compliant fuels and provide clear signals on port dues for low-sulphur shipments to reduce disruption during the month of transition.
  3. Tax authorities: publish current VAT guidance, supply deferral rules where applicable, and monitor effects on costs and shipping activity.
  4. Industry associations: coordinate proposing and disseminating guidance; collect feedback on issues that arise at port calls and relay them to IMOs and national bodies.

Track IMO 2020 sulfur cap milestones: compliance tasks, enforcement, and penalties for non-compliance

Implement a phased compliance plan now: map ships, fuel options, and switching protocols; align with marpol Annex VI; set clear milestones for compliance tasks, enforcement, and penalties. peter from imos notes that coordinated measures reduce pollution and support maritime operations; this approach can be taken long-term and remains still relevant, although fuel markets shift. The option to use compatible low-sulfur fuels, blended fuels, or approved scrubbers adds flexibility, and added guidance from imos is welcomed by shipowners and port states. This event brings a clear incentive for early action, and enforcement will deter non-compliance and deliver environmental benefits that make the transition smoother for ships and the state group. The plan should be implemented now and can accommodate further adjustments as circumstances come and go.

Track progress with a focused table and three pillars: compliance tasks, enforcement actions, and penalties for non-compliance. Use a shared tracker to fit the global fleet, from state to port authorities, and ensure the data remains transparent for stakeholders. The tracker simplifies reporting, helps identify gaps, and encourages continued improvement in environmental performance. The added measure of consistent penalties strengthens deterrence and aligns incentives across the industry, making compliance more predictable for groups of ships operating in different states.

Assess VAT gap in European long-distance passenger transport: impact on pricing, subsidies, and cross-border billing

Recommendation: adopt an initial EU-wide method to estimate the VAT gap in European long-distance passenger transport and publish it annually to guide pricing, subsidies, and cross-border billing during the implementation of reforms. Since this measurement began, national authorities stressed that gaps vary by border dynamics and travel patterns, requiring ongoing verifying and adjustment.

Pricing impact: The VAT gap inflates fares relative to the true cost of service, especially on long-distance routes, and creates pricing distortions that can discourage modal shifts toward greener travel. By exposing the size of the gap, authorities can set targeted price adjustments, while ensuring that their subsidies cover actual operating needs without double counting their benefits. There is potential to align pricing with verified compliance, reduce cross-subsidization, and improve traveler transparency.

Subsidies and support: Many national schemes rely on VAT-compliant operators, but a persistent gap erodes subsidy effectiveness and their intended climate impact. Encouraged by tighter verification, subsidies can be redirected toward services that meet verified VAT status and clear performance metrics, ensuring their long-term sustainability and their contribution to reducing greenhouse gases.

Cross-border billing: Implement harmonized invoicing standards, shared VAT registries, and robust cross-border verifying across borders to minimize leakage. The option to integrate with maritime and land routes, whether rail, bus, or ferry, reduces friction in ticketing and strengthens enforcement at origin and destination points.

Enforcement and governance: Governments must act promptly to close the gap, as delay undermines pricing fairness and climate objectives. Enforcement tools should be aligned across national systems, with clear timetables for milestones, and they must address border-specific issues that arise in maritime-linked long-distance travel. This change benefits all stakeholders and supports consistent rules for fees and subsidies.

Context with IMO progress: ICS welcomed IMO progress on 2020 Global Sulphur Cap Implementation Issues, and imos work offers a blueprint for cross-sector coherence. peters notes that, there are many issues to harmonize across transport modes, including taxation paths; peters input highlighted that the VAT gap can influence pricing in ways that extend beyond ships and ports into overland long-haul networks. Since the maritime sector began applying stricter controls, governments began to consider parallel VAT reforms to support cleaner travel and fair competition.

Next steps: begin a national pilot in two cross-border corridors, verify VAT status at ticket issuance and settlement, and publish quarterly results. Said officials should describe how initial findings translate into concrete changes in pricing, subsidy design, and cross-border billing rules, while tracking greenhouse gas reductions and broader climate implications. Peter-related coordination and ongoing meetings will be needed to align national regimes with EU-wide standards, ensuring that the transition proceeds smoothly and that the enforcement regime remains robust to avoid delays or backsliding.

Leverage IMO progress to align EU climate objectives: actions that decarbonize shipping without compromising mobility

Adopt this sustainability-based plan to translate IMO progress into EU climate objectives, decarbonizing shipping without compromising mobility. This view rests on strengthened enforcement, clear guidance, and a group of member states, European agencies, and maritime industrys stakeholders. Since the IMO 2020 global sulphur cap began, port and fleet operations tightened their emissions performance, encouraging investment in cleaner fuels and shore-side power; before this shift, inconsistent rules across borders slowed progress. A sample approach aligns regulatory timelines, fuel availability, and reporting standards so the maritime sector can advance in a coherent, predictable manner.

Concrete actions to implement in the decade include: codifying binding European targets for sustainable fuel uptake and efficiency improvements; accelerating enforcement of fuel quality rules and emissions reporting; expanding shore power and LNG/low-emission bunkering infrastructure at priority ports; harmonizing monitoring, verification, and data sharing with a single guidance framework; establishing financing plans that combine member-state and EU funds to accelerate supply chains and deployment; creating a cross-border group to align maritime with aviation decarbonization plans and to share sustainability-based best practices; publishing a monthly sample of performance indicators to track progress and address delay risks; engaging with the organization and the IMO to ensure global alignment and minimize bureaucratic lag while preserving European competitiveness.

EU Military Mobility: evaluating how coordinated security and transport projects can deliver public and climate benefits

Establish an EU-level organization to oversee military mobility with a single funding line, aligning security objectives with transport milestones. This will reduce costs, create good coordination, and ensure a smooth start; the program began with a european pilot in 2021 and should expand in the year ahead with clear plans and monitoring.

As a sample, a 400 km european corridor could link three logistics hubs and two ports, with joint security checks and cross-border clearance. The plan would cut transit times by 2-3 days and reduce idle time by about 15%, yielding an economic win for their fleets and a clear demonstration of how coordinated steps can work from a single, coherent approach.

Monitoring dashboards explained: a quarterly KPI sheet tracks costs, transit times, and lane utilization. An under- and over-performance flagging system stresses accountability, and the organization can address bottlenecks within short cycles. This also keeps plans aligned with marpol rules and fuels, ensuring compatible handling of goods across borders and smoother implementation.

Incentive mechanisms should reward plans that deliver climate and environment benefits. The european initiative can set a small option for early adopters, with an incentive funded from the economic envelope to encourage faster implementation. By prioritizing fuel-efficient routes and switching to marpol-compliant fuels, greenhouse gas emissions can be reduced while keeping operations resilient and maintaining compatibility across states.

Implementation will begin with a staged approach: start a first joint corridor in 2025, then add two more by 2027. The plan will rely on an underlined set of milestones and a year-by-year budget, with funding for monitoring and training. The option to reallocate funds between security and transport tasks will come only with demonstrated results and credible risk assessments.

Potential climate benefits hinge on a shift to fuels with lower life-cycle greenhouse emissions and on modal shifts away from road transport. The european strategy aims for concrete reductions, while the environment benefits from reduced local pollutants. The plan coordinates with energy and transport ministries to ensure compliance and timely delivery, and stresses that monitoring and governance remain aligned with long-term plans and fiscal discipline.

Since initial pilots began, the european-led approach has shown that a good, costs-conscious organization can deliver public and climate benefits while keeping plans compatible with marpol and environmental standards.

Start with a compliant fuel plan: verify sulfur content below the marpol limit for all voyages and document this as initial steps; done across european states and industrys supply chains.

Establish a transparent monitoring framework acknowledged by flag authorities and industrys networks; hemmings, an officer, notes that this structure strengthens data quality and supports compliant operation, building faith among many states. This approach has been refined through pilot programs.

Develop long-term options: switch to low-sulfur fuels, install scrubbers where feasible, or explore LNG and biofuel blends; teething issues accompany this transition, but the potential gains justify the effort during the initial phase into a broader implementation. Each option should be assessed for feasibility.

Around maritime and aviation, the data show shared benefits when the agreement framework aligns with marpol limit; aircraft operations illustrate different cost profiles, yet monitoring reduces risk for both sectors across a decade of activity.
