Serverius and Fuzion are now part of Kolo, a Northern European data center platform.

Responsible Infrastructure for Long-term Growth

Rising energy costs and carbon reporting requirements create new operational risks. KoloDC delivers measurable sustainability that reduces those risks through transparent environmental impact, accountable governance, and strong community partnerships.

Kolo is built on three pillars of responsibility

Our approach balances environmental stewardship with practical business needs, delivering infrastructure that meets both your performance requirements and sustainability goals.

Environmental Commitment

Investing in high-efficiency systems and renewable energy sourcing across our data center platform.

Social Responsibility

Local employment commitment and diverse, inclusive workplaces.

Transparent Governance

Board-level ESG targets, ISO-aligned policies, and a CapMan-backed oversight framework.

Environmental commitment:
Efficient by design

We focus on measurable efficiency, not offsets. Our strategy invests in high-performance cooling, renewable energy, and smart tools that track and cut your carbon footprint with precision.

Efficiency

Cut wasted energy before buying offsets

We prioritize infrastructure efficiency over carbon credits. Our ongoing assessment and investment like new high-efficiency cooling systems in Meppel and Apeldoorn deliver measurable energy savings. At Piteå Arctic site, natural climate conditions enable up to 65% annual free cooling.

Innovation

Develop smarter ways to cut emissions

We’re developing new methods to measure and reduce environmental impact. Partnerships like the NADIKI project with University of Stuttgart will deliver the first system to calculate CO₂ per workload, enabling precise carbon accounting for compliance reporting.

Resilience

Design for climate shocks

Our resilience framework includes annual climate risk assessments across Nordic facilities, identifying vulnerabilities to flooding, extreme heat, and power grid disruptions. These assessments inform facility design and backup systems.

Circularity

Keep materials in use—recover, reuse, recycle

We integrate circular principles throughout operations. For example, our Atlas Stockholm facility exports waste heat to district heating, providing renewable heating for nearby communities. We also prioritize low-carbon materials and hardware recycling programs.

Project spotlight: NADIKI

Making AI’s carbon footprint visible in real time

Partnering with the University of Stuttgart, we’re pioneering real-time environmental tracking for AI workloads. Unlike traditional tools that rely on static averages, NADIKI aims to capture live energy consumption and correlate it with actual grid carbon intensity.

The result? True visibility into AI’s environmental impact, smarter workload scheduling during cleaner energy periods, and automated compliance reporting for EU regulations.

“Data centers today are like a black box. We aim to measure what’s happening inside that box.” — Professor Peter Radgen, University of Stuttgart

Social responsibility: People and community first

We believe sustainable business requires strong relationships with employees and local communities. Our approach focuses on inclusive workplaces, comprehensive safety programs, and partnerships that benefit the areas where we operate.

Inclusivity

Build teams reflecting varied backgrounds

We actively work to create diverse, inclusive workplaces across age, gender, and ethnicity. Our 30% female workforce and local hiring commitment at each site demonstrate our focus on representation that reflects the communities we serve.

Equity

Ensure equal opportunities for all employees

We prioritize equal pay, clear career pathways, and accessible facilities for all team members. Our ongoing policy development ensures fair treatment and advancement opportunities regardless of background or personal circumstances.

Safety

Keep everyone safe and supported

Comprehensive safety measures protect both our on-site technicians and employees who raise concerns. Our health and safety policies work alongside secure whistleblowing channels to maintain safe, supportive work environments.

Community

Support local suppliers and neighbourhoods

We prefer local suppliers and talent, creating economic value in our communities. Our Atlas Stockholm facility exports waste heat to district heating, while local employment statements formalize our commitment to regional hiring.

Transparent governance: Accountability you can trust

Strong governance ensures our sustainability commitments remain consistent through ownership changes and market cycles. We maintain rigorous standards for data protection and transparent reporting.

Integrity

Zero tolerance for corruption or data abuse

We maintain ISO-aligned security and anti-corruption controls across all operations. Our comprehensive data privacy and cybersecurity policies ensure client information remains protected while meeting the highest ethical standards.

Transparency

Share live data—no hand-picked numbers

We commit to sharing real-time PUE and other KPIs data without selective reporting. Our public metrics dashboard, launching in 2026, demonstrates our commitment to transparent environmental reporting.

Accountability

Tie ESG performance to leadership metrics

Our sustainability targets are integrated into board oversight and tied directly to our owner CapMan’s fund-level ESG metrics. This ownership structure ensures sustainability commitments extend beyond management changes and market pressures.

Assurance

Independent scoring

We pursue independent scoring of our sustainability claims through recognized standards. Our expected GRESB score in 2025 and upcoming public dashboard provide validation of our environmental and governance performance.

Build on responsible infrastructure

Your infrastructure choices today shape tomorrow’s operational costs and compliance requirements. Partner with Kolo for transparent sustainability metrics, proven efficiency improvements, and accountable governance that grows with your business.
