Sustainability
Path to a Greener Future
We acknowledge our responsibility to protect the environment and minimize our ecological footprint. We are committed to sustainable practices, pollution prevention, and compliance with environmental regulations. Our aim is to contribute to a greener, more sustainable future.
We have set several targets, like reducing our CO2 emissions by up to 90% in the next couple of years, and continuing to reduce energy consumption at the office by installing solar panels. We have already installed 2 emission reduction systems onboard our vessels and have obtained certification for the CO2 Performance Ladder and ISO 50001 Energy Management System.
CO2 Aware Management
As of August 2024, we are certified at tier III on the CO2 Performance Ladder. The Ladder is an instrument that helps organisations reduce their carbon emissions. In order to certify, we first gained insight into our company’s energy consumption and carbon footprint. We then set ambitious yet realistic goals for CO2 reduction and committed to publishing progress reports to ensure transparency. Furthermore, by participating in at least two initiatives annually, we aim to foster continuous collaborations towards mutual sustainability goals.
Below, we share our bi-annual updates to further ensure transparency. Our latest annual reports and certificates are available for download below. For our registration details, please visit our SKAO-page.
Our actions so far

- Implemented HVO40 fuel fleet-wide per January 2025, reducing total CO2 emissions by 26% in 2 years.
- Replaced our company cars with smaller and more efficient engines, reducing their CO2 emissions by up to 35%.
- Reduced our overall energy consumption in offices, and aiming for net-zero consumption with solar panels in 2026.
- Compensating for emissions from our company cars with Travel Card’s CleanAdvantage program.
- Installed 2 DISCOM emission reduction systems on our Safety Standby Vessels with more to come.
- Regularly participate in Sustainability Initiatives throughout Europe.
- Replaced all office lighting with LEDs, reduced the number of printers and optimized our climate control system.
- Certification for the CO2 Performance Ladder to ensure our continuing improvement.
- Continuing to invest in sustainable improvements, such as rebuilding or buying more efficient ships.
Annual CO2 Progression
We began reporting our emissions in 2022, which now serves as our index year. At that time, the adoption of ChangeXL had already delivered a 9% CO₂ reduction, laying the groundwork for more ambitious targets.
In 2024, we achieved our first significant milestone: a 19% CO₂ reduction compared to 2022 emissions, driven by the fleet-wide implementation of HVO30. Building on this momentum, we have transitioned to HVO40 as of 1 January 2025, which is expected to reduce CO2 emissions by up to 26%. This brings us closer to our long-term ambition of a 82% reduction in emissions by 2031.
Bi-annual Highlights
Tracking the impact of our measures is essential to evaluating their effectiveness. Below is an overview of our CO2 emission reduction results compared to our targets. We provide a brief recap of our goals, followed by the realised reduction. For a more in depth analysis, please refer to our annual reports, available for download below.
To advance our mission towards a greener future, we implemented HVO40 across the fleet in January 2025. When HVO40 was unavailable in foreign ports, we compensated by bunkering HVO100 in Dutch ports, ensuring total emissions remained aligned with our reduction targets.
In the first half of 2025, our vessels consumed and emitted:
6.0 million litres HVO40 – 3,531 tonnes CO₂
2.0 million litres MGO – 3,836 tonnes CO₂
0.2 million litres HVO100 – 60 tonnes CO₂
0.1 million litres MGO-CXL – 337 tonnes CO₂
Thanks to the switch to HVO40 and a slight decrease in total fuel consumption compared with the same period last year, our scope 1 and 2 CO₂ emissions are projected to be 31% lower than mid-2022 levels.
In August, Glomar will carry out the necessary roof reinforcements to accommodate solar panels at our office. We expect installation to be completed and operational within a month, enabling us to achieve a 70% reduction in scope 2 emissions through the use of renewable solar energy.
By the end of 2024, the fleet-wide implementation of HVO30 resulted in achieving our revised target of a 19% CO2 reduction compared to 2022. This target was adjusted down from the original 28% after recognising that the baseline year (2022) already included the use of a ChangeXL blend, which had already reduced emissions by 9% compared to MGO.
Given that 99% of our total emissions fall under Scope 1, this 19% reduction applies nearly in full to our overall emissions footprint. We have also made progress in Scope 2 emissions, achieving a 35% reduction through the installation of LED lighting in the office and optimisation of the air conditioning system.
Scope 3 emissions have decreased by 8% compared to 2022, primarily due to a reduction in declared kilometres. However, as outlined in our annual report, flight-related emissions for both 2022 and 2023 have been adjusted due to insufficient records. For these years, we have applied the 2024 flight emission figures to ensure consistency and prevent inaccurate conclusions about an apparent increase in 2024.
Our goal was to implement HVO30 fleet-wide by January 2024 and achieve a 28% reduction in scope 1 and 2 CO2 emissions. Unfortunately, HVO-fuel is not always available in some ports. To compensate, we began occasionally bunkering HVO100, striving to achieve the equivalent of CO2 reduction from HVO30.
In total, our vessels consumed 2 million liters of HVO fuel and 1.26 million liters of Marine Gasoil, amounting to approximately 3.3 million liters of fuel. These fuels emitted 5.114 tonnes and 4.457 tons of CO2, respectively. Despite a 7% increase in CO2 emissions in mid-2023, we managed a 12.5% reduction so far.
CO₂ emissions from company cars have decreased by 32% since 2022. Energy consumption at the office and emissions from business travel have remained relatively stable. From 2024 onwards, flight emissions are being tracked more accurately, supporting a more comprehensive and transparent reporting process. As a result, the 2024 flight emission figures have also been applied retrospectively to 2022 and 2023.
SDG Commitments
As an offshore charterer, we are committed to supporting a more sustainable future. Where possible, we align our activities with broader sustainability objectives and support responsible practices within the offshore chartering industry. Our operations play a key role in offshore wind and renewables, while continuous improvements are made to enhance efficiency and reduce environmental impact at sea.
We actively adopt energy-efficient solutions, including the increasing use of HVO. This drop-in fuel, produced entirely from certified waste or residue feedstocks, can reduce carbon emissions by up to 89% without requiring engine modifications. By bunkering HVO, sailing at ECO-speed where feasible, and optimising port calls, we minimise emissions and avoid unnecessary fuel consumption.
Sustainability is further embedded through operational and technical choices. The rebuilding of two vessels and the construction of a new vessel provide opportunities to integrate future-proof, sustainable innovations. Each vessel operates under a Garbage Management Plan, with crews trained to handle waste responsibly and reduce marine pollution. In parallel, we collaborate closely with industry partners and stakeholders to drive innovation, share knowledge, and strengthen sustainable practices across the offshore chartering sector.
