📊 Emissions Reporting and Verification (MRV): Compliance Essentials Every Shipowner Should Know

My name is Davide Ramponi, I am 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 exciting 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.

Today’s post is all about a topic that combines regulation, environmental protection, and digital transformation: Emissions Reporting and Verification, also known as MRV.

New environmental frameworks from the EU and the IMO now require shipowners and operators to collect, verify, and report their vessels' greenhouse gas emissions. What does this mean for your fleet? Which technical systems need to be installed on board? And what are the risks if you don’t comply?

In this article, I’ll explain the MRV regulations you need to know, show how shipowners can implement the requirements onboard, explore digital tools that simplify the process—and share practical tips to stay ahead of the curve.

🌍 What Is MRV and Why Does It Matter?

MRV stands for Monitoring, Reporting, and Verification, a regulatory framework that aims to reduce greenhouse gas emissions in maritime transport. The system requires shipping companies to track their vessels’ emissions data and submit regular reports to authorities.

Who enforces MRV?

• EU MRV Regulation (Regulation (EU) 2015/757):Applies to vessels ≥5,000 GT calling at EU/EEA ports, regardless of flag.

• IMO DCS (Data Collection System) under MARPOL Annex VI:Applies to all vessels ≥5,000 GT on international voyages.

📌 Both systems require annual reporting of fuel consumption, distance traveled, and time at sea—but with different verification mechanisms.

🧾 MRV Requirements Under EU and IMO Regulations

Though the EU and IMO frameworks share common goals, they differ slightly in their approach. Here's a breakdown of the key requirements:

✅ EU MRV System

• Monitoring of CO₂ emissions for all voyages to/from and between EU ports

• Annual Emissions Report to be submitted to a verifier

• Issuance of a Document of Compliance (DoC), which must be kept onboard

• Penalties and port bans for non-compliance

✅ IMO DCS System

• Monitoring of fuel consumption, distance traveled, and hours underway

• Annual submission to the Flag State or Recognized Organization

• Data is then sent to the IMO for trend analysis—not public disclosure

• Supports CII (Carbon Intensity Indicator) and SEEMP Part III

💡 Tip: If your vessel trades both inside and outside the EU, you may need to comply with both systems simultaneously—using separate reports.

⚙️ Technical Implementation Onboard: From Theory to Practice

Complying with MRV requirements isn’t just a paperwork exercise—it requires technical infrastructure onboard to collect and manage accurate data.

What needs to be installed or upgraded?

1. 📡 Fuel Flow Meters or Bunker Delivery Notes (BDNs)

To measure fuel consumption, most vessels choose between:

• Flow meters (more accurate, continuous data)

• BDNs and tank soundings (manual, but acceptable)

2. 🧭 Voyage Data Recording

Monitoring voyage distance and time at sea is usually handled via:

• Bridge logbooks

• Electronic Voyage Reporting Tools

• AIS and GPS integrations

3. 📈 Emissions Monitoring Software

To calculate and aggregate emissions data across multiple systems.

💬 Real-World Tip: Crew training is critical. Even the best system fails if officers don’t know how to input or extract the right data.

⚠️ The Cost of Non-Compliance: Risks, Fines & Reputational Damage

Failure to comply with MRV regulations is more than just a regulatory hiccup—it can lead to serious consequences. Here's what’s at stake:

🚫 Financial Penalties

• EU ports can impose fines or deny entry for missing or invalid Documents of Compliance

• Charterers may demand MRV-compliant vessels only, limiting commercial opportunities

❗ Legal & Operational Risk

• Repeated non-compliance can result in a ban from EU ports

• Loss of insurance coverage if MRV obligations are seen as neglected operational duties

💣 Reputational Damage

• Public MRV reports (EU) can affect your company’s image and relationships with ESG-conscious clients

🎯 Bottom Line: MRV is not optional. Compliance = market access.

💻 Digital Solutions: Tools That Make Compliance Easier

The rise of digital tools has made MRV reporting much easier—if you know where to look. Here are some platforms shipowners should know:

🌐 Leading MRV Software Solutions

1. StormGeo (A part of Alfa Laval)

Offers an integrated MRV + IMO DCS dashboard with real-time analytics.

2. Verifavia Shipping

Specializes in EU MRV compliance and verification. Also offers CO₂ calculators and dashboard tools.

3. DNV Navigator

Combines emissions reporting with voyage and port documentation—ideal for large fleets.

4. NAPA Logbook

A digital logbook that integrates with onboard sensors and produces IMO-compliant fuel and voyage reports.

📊 Best Practice: Choose software that allows multi-regime compliance (EU & IMO) and integrates with your existing ECDIS or VDR systems.

🛠️ Practical Recommendations for Shipowners

Even with the best intentions, implementation can be overwhelming. Here are five actionable steps to ensure MRV compliance across your fleet:

1. 📅 Prepare a Monitoring Plan Early

This is the cornerstone of EU MRV compliance and must be approved by a verifier. For new ships, this should be ready before first EU port call.

2. 🧑‍✈️ Train the Crew

Ensure bridge and engine staff know how to record, retrieve, and validate emissions and voyage data. Hands-on workshops help build internal buy-in.

3. 🔄 Automate Where Possible

Manual reporting is prone to errors. Automate data collection via integrated bridge and engine room systems.

4. 🤝 Work With a Recognized Verifier

Choose a class society or independent body authorized to verify your MRV reports. Good communication avoids last-minute surprises.

5. 🔁 Conduct Internal Audits

Review your emissions data monthly or quarterly to catch inconsistencies early. This avoids panic before the reporting deadline.

🧭 Conclusion: MRV Compliance Is More Than Just a Checkmark

Emissions reporting is here to stay—and shipowners who act now can turn a regulatory obligation into a commercial strength.

✅ The EU and IMO both require emissions reporting—but with distinct systems and verification needs

✅ Onboard systems like flow meters, logbooks, and digital dashboards are essential for reliable data collection

✅ Non-compliance risks range from fines to lost charters and reputational damage

✅ Digital tools and automation reduce errors and simplify the reporting burden

✅ Proactive planning, staff training, and regular internal reviews ensure long-term success
