Results
The Green Marine Europe program demonstrates year after year its ability to encourage its participants to go beyond regulatory requirements.
Green Marine Europe requires participants to adopt practices and technologies that will have a direct impact on the field.
The annual performance report displays all the individual results of the certified participants in addition to the overall average and an analysis of the environmental performance for the year concerned. Their progress is evaluated on a 1-to-5 scale.
A Key Strategic Driver
In 2026, Green Marine Europe’s overall membership surpassed the 100-member mark. This growth confirms the value of a framework tailored to a regulatory and industrial landscape undergoing profound change. In Europe, the certification aligns directly with the European industrial maritime strategy and Port strategy, both of which call for a coordinated approach to environmental performance across the maritime value chain.
Building Momentum and Driving Progress
While the number of participants rose by 30% in one year, 37 of which are certified, and the number of reported indicators has increased nearly sixfold since 2019, the overall average has remained above Level 2. Between 2019 and 2025, the number of reported indicators increased from 48 to 280. Over the same period, the overall average fluctuated between 2.2 and 2.7, reaching 2.4 in 2025.
Ports: Establishing an Initial Benchmark
Officially launched in 2026, the Ports program already includes eight port authorities, two of which have been certified for their 2025 operations. This first round of port certification establishes an initial benchmark, confirming that the framework can be applied across different port configurations, progressively generating comparable data, and helping build a European community of practice.
2025 Highlights
In Europe, the number of participants increased by 30% in one year, reaching 47, including 37 certified participants. This continued growth confirms the appeal of the certification and its relevance in addressing the challenges specific to the European context.
Ship owners remain the program’s longest-standing and largest cohort. Twenty-nine ship owners were certified for their 2025 results. Their average performance rose from 2.5 to 2.6, and 60% of the 25 returning ship owner participants improved their performance.
The shipyards program grew from four to seven participants, a 75% increase, with six certified for the 2025 reporting year. Their average performance improved from 2.1 to 2.4 out of 5. All four returning shipyards improved their performance.
Officially launched in 2026, the Ports program includes eight port authorities. The ports of Santander and Cartagena are certified for 2025. With an average performance of 2.5, they demonstrate performance beyond regulatory requirements and the implementation of industry best practices.
The most significant improvements in the 2025 results were achieved by shipyards in the Air Emissions—Greenhouse Gases and Air Pollutants and Waste Management performance indicators, each recording an average increase of 33%.
Continual improvement
The number of participants achieving the higher Levels 3, 4, and 5 increased in this seventh year of assessment, reflecting both the maturity of the Green Marine Europe program and participants’ commitment to continuals improvement, a principle at the core of the certification.

An Environmental Compass
Green Marine Europe presents its 6th set of annual results. The program is now firmly established within the European landscape. Green Marine Europec is a recognised certification by the maritime industry, a steering tool that structures approaches, guides technical choices, and motivates teams. It is a compass in a demanding context, and a map that gives meaning to our actions.
An ocean of possibles
Green Marine Europe presents its 5th set of annual results. This anniversary is an ideal time to take stock of what has been achieved to date, as well as identify the opportunities for an even more sustainable future for the European maritime industry. These five years have reflected the values that drive the program: dialogue, expertise, sharing. These values make Green Marine Europe a community rallied around the reduction of its environmental impacts.
Sustainability, Requisites, Progress
These are what drive Green Marine Europe’s approach! After three years of clear progress, the results for 2022 present a slight decrease in the overall average to put it at 2.6 (on the 1-to-5 scale). The influx of new participants explains this plateau and their generally needed time to familiarize themselves with the program’s requirements.
Past performance reports
What progress in just three years!
For its third year of evaluation, the environmental certification program's results demonstrate a continuous improvement in the performance of certified ship owners with an overall average of 2.7 on a scale of 1 to 5.
Twice the certified ship owners!
For this second year of evaluation, Green Marine Europe has doubled the number of its participants, certifying 11 ship owners. Evolution was also on the agenda in terms of the environmental certification program’s scope, with the addition of an eighth performance indicator relating to ship recycling.
1st cohort performs beyond compliance
Although this is the first year of evaluation and the initial group of certified ship owners, the results already bear witness to their commitment to the environment. In fact, all six ship owners far exceeded the program’s minimum performance requirements for the first year of the certification, obtaining at least Level 2 for one of the indicators.

The environmental certification program’s success is largely based on its ability to identify and address key issues related to sustainable maritime transportation.
