My name is Davide Ramponi, I’m 20 years old and currently training as a shipping agent in Hamburg. On my blog, I take you with me on my journey into the fascinating world of shipping. I share my knowledge, my experiences, and my progress on the way to becoming an expert in the field of Sale and Purchase – the trade with ships.
The maritime industry is under growing pressure to reduce its carbon footprint and improve transparency. While topics like decarbonization and green fuels dominate the headlines, there’s a foundational element every shipowner must master first: emissions reporting and verification.
Whether your vessel is calling at EU ports or operating globally, regulatory authorities now expect accurate, verifiable CO₂ emissions data. And this isn’t just a box-ticking exercise—non-compliance can lead to fines, detentions, or even bans from major trading zones.
That’s where MRV (Monitoring, Reporting, and Verification) systems come in.
So, what does MRV compliance involve under the EU and IMO frameworks? How can you implement the right tools onboard? And what are the practical steps to make sure your fleet is audit-ready, every single year?
Let’s break it down. 🧾🌍
What Is MRV and Why Does It Matter? 🧭📘
MRV stands for Monitoring, Reporting, and Verification—a regulatory framework designed to track greenhouse gas emissions from ships. The goal is to support climate transparency, push for efficiency, and hold operators accountable for their environmental impact.
In shipping, MRV focuses primarily on CO₂ emissions linked to fuel consumption.
🔍 Two Key Frameworks:
EU MRV Regulation (Regulation (EU) 2015/757)
Applies to vessels ≥5,000 GT calling at EU/EEA ports
Requires annual reporting of CO₂ emissions per voyage
Includes routes into, out of, and within EU ports
Verified data must be submitted to the European Commission
IMO DCS (Data Collection System) under MARPOL Annex VI
Applies to all ships ≥5,000 GT on international voyages
Reports fuel consumption, distance travelled, and operating hours
Data is submitted to the flag state, not the EU
🧠 Important: EU MRV and IMO DCS have similar goals but different scopes, deadlines, and reporting formats. Most operators must comply with both.
MRV Compliance Timeline: What Shipowners Must Know 🗓️📌
Let’s take a closer look at the annual EU MRV timeline. Here’s what needs to happen—and when.
The IMO DCS follows a similar cycle, but:
Data goes to the flag state (or RO like DNV, LR, etc.)
Deadlines may vary depending on national rules
⚓ Tip: Keep a master MRV calendar to manage deadlines across both regimes—especially for mixed fleets.
Technical Implementation Onboard Vessels 🛠️📋
For MRV to work, your vessels need to collect accurate, reliable emissions data during every voyage.
Here’s how to do that.
🧾 1. Develop a Monitoring Plan
The Monitoring Plan outlines:
Fuel measurement methods (e.g., bunker delivery notes, flow meters, tank readings)
Emission factor application
Data sources and responsible personnel
Correction procedures for missing or inconsistent data
This plan must be:
Verified by an accredited verifier (for EU MRV)
Submitted to the flag state (for IMO DCS)
📘 Don’t use a template blindly—customize the plan to reflect your vessel’s fuel systems and voyage patterns.
📈 2. Collect and Store Data
Data collection covers:
Type and amount of fuel consumed
Start and end ports of voyage
Distance sailed and time underway
Cargo carried (for efficiency metrics)
Common data sources:
Engine room logs
BDNs (Bunker Delivery Notes)
GPS tracking
Flow meter readings
Store data in a centralized, secure system and ensure it is backed up regularly.
🧪 3. Verify and Submit
Have your emissions report verified by an independent body (EU MRV only)
Submit data to:
The THETIS-MRV platform (EU)
The flag state or Recognized Organization (IMO)
You will then receive:
A Document of Compliance (DoC)
Feedback for corrective actions, if needed
Risks of MRV Non-Compliance ❌💸
Mistakes in MRV aren’t just paperwork errors—they can derail entire voyages.
🚨 Common Pitfalls:
Incomplete voyage data or fuel logs
Delayed or missing verification
Failure to carry a valid DoC
Using incorrect emission factors
Discrepancies between ship logs and submitted reports
⚖️ Consequences:
Administrative fines from national authorities
Port State Control (PSC) detentions
EU blacklisting after repeated non-compliance
Loss of trust with charterers and regulators
Ineligibility for carbon trading incentives
💣 Under EU MRV rules, vessels that fail to comply for two consecutive years may be banned from EU ports.
Digital Tools That Simplify MRV Compliance 💻📲
Manual data entry is no longer practical—or safe—when it comes to emissions reporting. That’s where digital solutions come in.
🌐 Recommended Software Platforms:
DNV Veracity
Covers EU MRV and IMO DCS
Real-time fleet analytics and DoC management
Used by many flag states as default verification tool
NAPA Logbook
Automated engine data capture
Onboard and shore-side modules
Integrated with fuel performance metrics
StormGeo (by Alfa Laval)
Full MRV/DCS automation
Real-time alerts for data gaps
Weather routing for carbon-efficient operations
ABS NS Voyage Manager
Cloud-based data collection
CII scoring and MRV dashboard
Easy integration with shipboard systems
✅ Tip: Choose a system that integrates MRV with CII and EEXI tracking to avoid duplication of effort.
Practical Recommendations for MRV-Ready Shipowners 🧭🧾
A successful MRV strategy is more than ticking boxes—it’s about building a culture of environmental responsibility and operational accuracy.
✔️ 1. Appoint a Compliance Champion
Designate a team member (onboard or ashore) to oversee:
Monitoring Plan updates
Data consistency checks
Communication with verifiers
This person should work closely with technical and operational teams.
✔️ 2. Train the Crew
Ensure officers and engineers understand:
How to collect fuel and voyage data
Why accurate reporting matters
What documentation is required during PSC inspections
🎓 Use case-based training—like missing BDNs or sensor failures—to build real-world skills.
✔️ 3. Conduct Pre-Verification Audits
Before submitting data:
Cross-check fuel logs with engine hours
Recalculate emissions using a second method
Have a third person review the Monitoring Plan
✔️ 4. Align MRV with Green Strategy
Use MRV data to:
Improve operational efficiency
Benchmark CII ratings
Apply for green financing or port fee reductions
🌱 Sustainability starts with measurement—and MRV provides the baseline.
Real-World Example: Averted Detention Thanks to MRV Diligence 📉✅
A dry bulk carrier calling at Rotterdam was randomly selected for MRV inspection. Thanks to:
A well-documented monitoring plan
A digital logbook system
A trained chief engineer
…all records matched, and the inspection was completed in under 90 minutes—no delays, no fines.
Lesson: A clean MRV record is also a reputation booster.
Conclusion: MRV Compliance Is Your License to Trade 🌍🧾
In today’s decarbonizing maritime sector, emissions data isn’t optional—it’s essential. MRV compliance keeps your fleet legal, your charters flowing, and your environmental performance transparent.
Let’s recap:
MRV is governed by both EU and IMO rules—know the difference
A good Monitoring Plan and digital tracking tools are key
Mistakes can lead to fines, detentions, or trade bans
Use MRV data for more than compliance—make it part of your green strategy
