How Vastint turned sustainability data into a strategic advantage
Driving ESG improvements at scale

As sustainability expectations rose across Europe, Vastint faced the challenge of transforming ESG data into actionable insights that could guide meaningful progress – as well as ensuring regulatory compliance.
With over 100 properties (offices, hotels, homes etc) across multiple countries, consistent and structured data collection was a challenge. Teams often worked with manual spreadsheets, limiting visibility across locations. Meanwhile, the growing complexity of CSRD and ESRS requirements made it difficult to identify what truly mattered most for the business.
Vastint needed a structured, data-driven approach to:
- Clarify which sustainability issues were most material to their operations
- Build a unified foundation for ESG data and reporting
- Empower teams to focus on improvement, not just compliance
The solution
We partnered with Vastint to design and deliver a two-phase programme that combined strategic clarity with digital enablement, helping them understand where to focus and giving them the tools to act.
Phase 1: ESG foundations & materiality alignment
Our advisory work began with a deep dive into Vastint’s sustainability data and priorities:
- Data & core reporting requirements: A series of workshops defined Vastint’s ESG reporting foundations, covering CO₂ data needs, organisational structures, and reporting processes.
- GHG data & landscape mapping: We built a structured inventory of all GHG data sources — mapping frequency, quality, and automation potential to assess readiness.
- Double materiality, impacts, risks, opportunities and material topics advisory: Through group and regional workshops, we identified material topics aligned with business impact and stakeholder relevance. This process created clarity on which sustainability areas mattered most to Vastint’s long-term success.
- Action plan: Findings were consolidated into a group-wide gap analysis and roadmap for improving data maturity, ESG performance, and CSRD alignment.
This phase gave Vastint a clear view of their sustainability landscape – linking business priorities with ESG risks, opportunities, and measurable goals.
Phase 2: ESG Optimiser implementation
To embed this strategy, Ikano Insight implemented ESG Enterprise Optimiser which uses IBM Envizi ESG Suite, tailored to Vastint’s organisational structure and data hierarchy.
Key features included:
- Automated calculation of Scope 1, 2, and 3 emissions
- Regionally specific emission factors and renewable energy accounting
- Integrated ESG reporting framework with workflow and collaboration tools
- Dashboards allowing property and project managers to track progress in real time
Training and onboarding ensured consistent adoption across teams, turning ESG data into a living part of Vastint’s business operations.
The outcome
The collaboration strengthened Vastint’s ESG management approach – creating a unified platform for continuous sustainability improvement.
- Strategic focus: Vastint identified its most material sustainability topics, enabling sharper decision-making and prioritisation of high-impact initiatives.
- Improved performance: Clear visibility into emissions data allowed Vastint to benchmark building performance, track progress, and measure improvements over time.
- Efficiency gains: Automated data capture and standardised workflows replaced manual spreadsheets, saving time and reducing error risk.
- Stakeholder alignment: Workshops built shared understanding across sectors, ensuring everyone worked toward the same sustainability goals.
- Actionable insights: Real-time dashboards provided the visibility needed to manage carbon performance at scale and focus investments where they matter most.
The impact
By aligning sustainability strategy with robust data and digital tools, Vastint is now equipped to:
- Direct resources toward their most material sustainability issues
- Set measurable goals and track performance across regions and projects
- Strengthen internal collaboration and accountability
- Reduce environmental impact with confidence and precision
- Position sustainability as a driver of long-term business value
Vastint’s sustainability strategy does more than meet compliance – it gives the organisation a clear, data-backed foundation for progress. With insight into what truly matters, Vastint can focus on creating sustainable impact where it counts most.
