Dependable
air power —
built to last.
Our fifth sustainability report, and our first under the European VSME standard. Covering all five group entities for FY 2025.
Sustainability is
who we are.
I have been part of Sperre for many years, and every year I am reminded that sustainability is not a programme we run — it is who we are. It was part of this company long before that word became common in boardrooms. The people who built Sperre in 1938 understood that a product worth making is a product worth making to last.
That belief still lives here — in the way our engineers approach their work, and in the everyday conversations where someone asks whether we can do something a little better. For us, sustainability is not a separate agenda. It is simply part of how we look after the people who work here, the customers who rely on us, and the environment around us.
"We say it's personal — and we mean it. Every compressor we build carries the responsibility of the people who made it, and the trust of the people who depend on it."
Our compressors remain in operation for 30 years or more — as long as the vessel or application is in operation. This longevity is perhaps our most personal contribution to sustainability: fewer replacements mean fewer raw materials consumed, less energy spent in manufacturing, and a smaller footprint left on the world.
To our partners, customers, and stakeholders: thank you for holding us to a high standard. We welcome that. It is what keeps this personal.
Years perfecting compressed air systems for the world's maritime fleet.
Every 5th ship in the world carries a Sperre compressor system.
Years in operation — as long as the vessel needs it. Longevity is our sustainability strategy.
Built to last.
Built to matter.
Sperre designs, manufactures, and services compressed air systems for the global maritime fleet — both piston and screw compressors. Our headquarters and production facility is at Ellingsøy, Ålesund. We operate four sales and service offices in Shanghai, Singapore, Busan and Rotterdam.
Our compressors remain in operation for 30+ years — as long as the vessel or application is in operation. The longer our products last, the less needs to be made.
Replace parts, not whole compressors. 92% of our waste is sorted. Spare parts available for the lifetime of every product we sell.
Zero fatalities in 2025. Safe workplaces, fair pay, and respect for human rights — in our own operations and across our supply chain.

Our fifth report.
Our first under VSME.
This is our fifth sustainability report, and our first prepared under the VSME standard — the Voluntary Sustainability Reporting Standard for non-listed SMEs, issued by EFRAG in December 2024. We report under the Comprehensive module. The parent undertaking, Sperre Air Power AS (Aksjeselskap), prepares this report on a consolidated basis covering all five group entities for FY 2025. Our headquarters and production site at Ellingsøy is the primary reporting boundary for operational and environmental data. Our four sales offices — Shanghai, Singapore, Busan and Rotterdam — contribute data on energy, water, company cars, commuting and business travel. The financial data in this report is consistent with the consolidated financial statements for the same period.
Our four material
sustainability
priorities.
Identified through our Double Materiality Assessment in 2024. These four topics reflect where we have the most significant impact — on people and on the environment.
The DMA was conducted by management with input from key stakeholders including employees, customers, and suppliers. Both impact materiality and financial materiality were assessed. Our ESG & HSEQ Policy and Code of Conduct are available upon request. Environmental and safety policies are implemented through our ISO management systems (14001, 45001, 50001).
GHG emissions management, energy transition, pollution prevention across operations and value chain. Covered by ISO 14001 and ISO 50001.
Long product lifetimes, component-level replacement, waste reduction, supplier packaging initiatives and downstream lifecycle support.
Structured training, individual development plans, e-learning platform, knowledge sharing and career development across all locations.
Human rights due diligence, Norwegian Transparency Act compliance, Code of Conduct requirements for suppliers and agents.
Our contribution
to the SDGs.
We support the maritime sector's transition toward more sustainable operations by delivering reliable, long-lasting compressor systems that form part of the technical foundation for lower-emission shipping.
Sperre has been a signatory to the UN Global Compact and the UN Sustainable Ocean Principles since 2020.
Safe workplaces and employee well-being. Sick leave improved from 3.0% to 2.2% in 2025, with zero fatalities across all sites.
Durable, high-quality systems built to last 30+ years, reducing the need for replacement and supporting resilient maritime infrastructure.
We replace parts, not whole compressors. Waste recycling improved from 52% to 67% over three years.
Our systems enable vessels using lower-emission technologies. We run on 94% renewable electricity and track GHG across all three scopes, with formal reduction targets planned for 2026.
Our climate
footprint.
We manage our environmental impacts systematically — ISO 14001 has guided our work since 2011, and ISO 50001 has strengthened our energy management since 2024. Our compressors remain in operation for 30 years or more, because a compressor that never needs replacing is the most sustainable one we can build.

Category 11 (use of sold products) could not yet be reliably estimated. We are exploring methods to include this in future reporting cycles.
We manage our environmental impacts at Ellingsøy through ISO 14001, certified since 2011. In 2025 there were no contamination incidents, and none of our locations are near biodiversity-sensitive areas.
Replace components,
not compressors.
Non-hazardous (82%)
Hazardous (18%)
Hazardous waste reported to authorities per Norwegian regulations.
Our compressors are built to last — decades in operation, not years. That means less new manufacturing, less material use, and less waste. We keep spare parts available for the lifetime of every product we sell.
We are continuously working to substitute input materials to reduce harm on the environment — both by finding more environmentally friendly materials and more energy-efficient alternatives.
Mass flow of materials (B7 §38c): Structured weight data collection for all components is being implemented in 2026.
B8–B10 — Our People136 people.
5 countries.
One culture.
Non-employee workers (C5): Sperre does not engage significant numbers of non-employee workers (contractors, agency workers, or self-employed persons) in its operations. Temporary staffing needs are covered through the 11.6 temporary FTE reported above.
ISO 45001 certified since 2013. Our goal is zero fatalities and zero serious injuries.
A good working environment and fair working conditions are important to us. We follow up systematically through risk assessments and regular health check-ups via occupational health services. In addition, we offer benefits such as pension schemes, insurance programmes above mandatory requirements, and gym membership support. We also have a dedicated working group focused on equality and non-discrimination.
Training hours (B10 §42d): Average annual training hours per employee broken down by gender will be reported from FY 2026.
We adapt quickly and move with purpose.
We listen, learn, and notice what matters.
We are open, honest, and easy to work with.
We take ownership and stand behind our commitments.
Zero incidents.
Full transparency.

We comply with Norway's Transparency Act and conduct annual questionnaires and audits across our key supplier relationships. A more systematic digital platform for human rights monitoring is being built for 2026.
We have a dedicated whistleblowing procedure guiding our employees in how to register events. For external stakeholders, we provide an open channel via whistleblowing@sperre.com. All reports are handled confidentially and in accordance with Norwegian law.
We've taken an initial look at our climate-related risks. The main ones are in the shipping sector — IMO decarbonisation targets and EU ETS are changing what our customers need. We see that as an opportunity as much as a risk. Physical risks at Ellingsøy are low. We'll build a more structured climate risk process in 2026.
Built to last.
Committed
to improve.
Five reports in. We're proud of what we've built, and honest about what still needs to improve. Below are our priorities for 2026.
