LEONI reduces carbon calculation time from weeks to days

Challenges

• Spreadsheet-based emissions calculations
• Limited Scope 3 coverage and data granularity
• Time-intensive data validation and PCF generation cycles
• Limited end-to-end transparency and traceability across sustainability data workflows
• Strong reliance of decentralized expert knowledge and manual coordination processes

Prior to the transformation, LEONI managed emissions calculations through a combination of distributed tools and spreadsheet-based workflows. Sustainability data was gathered from multiple operational systems and consolidated largely through manual processes, resulting in extended processing timelines and limited comparability across reporting periods.

For product carbon footprints, complex wiring systems with many components made manual LCA mapping time-consuming and difficult to scale.

Solution

LEONI implemented SpheraCloud Corporate Sustainability (SCCS) alongside its Product Sustainability LCA solution to address both enterprise-wide reporting and product-level carbon footprinting.

The SCCS solution enabled centralized data collection, automated emissions calculations, and direct linkage between reported data and supporting evidence (e.g., invoices). This improved transparency and reduced reliance on manual processes.

Sphera’s flexibility allowed LEONI to go beyond carbon accounting, supporting multiple sustainability frameworks (e.g., CDP, EcoVadis, UNGC, CSRD readiness) within a single system.

On the product side, the LCA database and automated BOM mapping capabilities significantly simplified LCA modeling for complex products. Built-in datasets and transparent emission factors enabled detailed, auditable calculations aligned with customer requirements.

The combination of automation, database transparency, and system flexibility allowed LEONI to scale sustainability efforts without increasing headcount.

Results

LEONI achieved significant efficiency gains and improved data quality across both corporate and product-level sustainability processes.

• Reduced emissions calculation and validation time for reporting from weeks to near-instant results
• Reduced product carbon footprint modeling from 1 month to only days through automated mapping
• Enabled broader Scope 3 coverage and more detailed upstream/downstream analysis
• Improved data traceability and auditability, reducing risk from personnel changes
• Allowed the same team to analyze more categories and datasets without increasing resources

These improvements have strengthened LEONI’s ability to respond to customer requirements, support decarbonization planning, and prepare for evolving regulatory demands.
