Emission reporting

According to the European Commission, international shipping is a large and growing source of greenhouse gas emissions, currently responsible for approximately 13% of GHG emissions from EU transport! Both the EU as well as the IMO (International Maritime Organization) aim to reduce the sectors’ GHG emissions and therefore require all ships of 5.000 gross tonnages or above to collect data and report on their emissions. This is where our performance monitoring solution comes in, which makes it incredibly easy to fulfil your duties in regards to emission reporting.

How We4Sea helps you with emission reporting

Basically, we support two kinds of emission reporting. For ship owners, we support formal compliance in reporting emissions. For charterers, we report on emissions of all chartered vessels, even when on voyage or period charter!

Emissions reporting for Ship Charterers

The We4Sea Emission Monitor monitors chartered vessels  through the concept of a Digital Twin. This  allows you to report all kinds of data, from fuel efficiency for ships to sea state- and weather data for charter companies, including the emissions that stem from every sailed mile. In addition, all of this information can be accessed online at any given time, regardless of location. We, therefore, call this part of our software remote emission reporting, since it reports on emissions automatically and from a distance, making the challenge trivial!

We also can report on emissions in compliance with The Sea Cargo Charter, to help charterers establish a common baseline to quantitatively assess and disclose whether shipping activities are aligned with adopted climate goals.

Compliance made easy for ship owners

Ship owners are required to report the emissions of all ships over 5,000 Gross Tonnage (GT). There are two different types of regulations that require these ships to report on their emissions. These are the EU-MRV (Measurement, Reporting, Verification), posed by the EU, and the IMO-DCS (Data Collection System), represented by the International Maritime Organization. Their requirements in regard to emission reporting are comparable but have some important differences among them as well. Both of these regulations aim to collect data which, in the future, can be used to increase fuel efficiency for ships effectively. Below you will find a short description of both regulations.

The European Commission aims to reduce emissions as a part of their efforts to reduce its domestic GHG emissions. The first step consists of the EU-MRV, which requires annual emission reporting of all ships above 5.000 GT from 2018 onwards, on European voyages.


Similarly, the International Maritime Organization requires all ships of over 5.000 GT to collect and report data annually to their database from 2019 onwards. This is determined in the IMO-DCS regulation.

Most vessels will have to report to both EU-MRV as IMO-DCS as they typically sail internationally. Our module can generate both an EU-MRV as well as an IMO-DCS report.

The Sea Cargo Charter establishes a common baseline to quantitatively assess and disclose whether shipping activities are aligned with adopted climate goals. The Sea Cargo Charter is consistent with the policies and ambitions adopted by member states of the UN’s International Maritime Organization, including its ambition to reduce greenhouse gas emissions from international shipping by at least 50% by 2050.

The Sea Cargo Charter allows for the integration of climate considerations into chartering decisions to favor climate-aligned maritime transport and thus enables leaders from diverse industry sectors to use their influence to drive change and promote shipping’s green transition.

We4Sea can support with emission reporting for all parties in the chain:

Completely certified

Our EU-MRV and IMO-DCS module has been independently verified and certified by Verifavia or all ship types and the commonly used emission monitoring methods. This means that our data collection method, our calculations and our reporting are fully compliant to both EU and IMO legislation. Also, our module was extended in 2019 with the possibility to download the data in a compliant XML file, which can be directly imported in the EU reporting tool Thetis.

Please find a copy of the certificates below for download.
