SIEGENIA builds a structured sustainability program and publishes verified EPDs with Sphera

Challenges

SIEGENIA faced growing sustainability demands without the systems needed to support them effectively:

• No structured sustainability framework or defined KPIs
• Fragmented, manual data collection across departments
• Lack of centralized, auditable carbon data
• Increasing customer demand for verified EPDs and transparency

In a construction market where sustainability credentials are increasingly required for business, the absence of reliable data and tools made it difficult for SIEGENIA to meet customer expectations efficiently or at scale.

Solution

SIEGENIA implemented SpheraCloud Corporate Sustainability and LCA for Experts to build a centralized and scalable sustainability data foundation.

The platform enables:

• Reliable KPI tracking and centralized data aggregation
• Corporate and product-level carbon footprint calculations
• Lifecycle assessments (LCAs) across all product variants—even in early development stages
• Access to recognized environmental databases and certification-ready methodologies

This foundation allows SIEGENIA to efficiently produce verified Environmental Product Declarations (EPDs) and respond to customer and regulatory requirements with confidence.

The solution is used across multiple business functions, including management, controlling, environmental management (ISO 14001 and ISO 50001), product development, marketing and sales.

Results

Despite its enterprise-wide impact, the Sphera solution is managed by just two individuals, each dedicating less than 5% of their time.
