From vehicle BOM to an audit-ready product carbon footprint.
Collect supplier evidence, preserve HMI’s existing LCA logic, calculate automatically with versioned Ecoinvent factors, and trace every kg CO₂e from Tier 2 to the vehicle-level result.
Switch roles, build a part, cascade to Tier 2, and watch it calculate.
The demo uses realistic automotive sample data for a CRETA front-seat assembly and follows the Phase 1 process described in the RFP.

Accepted Tier 2 inputs are locked into the Tier 1 submission snapshot before HMI validation. Tier 2 cannot cascade further in Phase 1.
Extract, standardize and map raw-material data.
IMDS PDFs remain editable after OCR. Material grades are standardized across JIS, ASTM, EN and IS before connection to approved LCA datasets.

Validate once, calculate automatically, and preserve every result version.
The background engine stores the Ecoinvent version, factor reference, methodology, input snapshot and formula path used for each result.
Automated validation checks
Calculation blocked
Resolve the blocking error and authorise or clear the warning before calculation can begin.
Calculation traceability
Every output can be drilled into from parent part to supplier, process, flow, factor and source evidence.

Review and approval workflow
Approved data is locked. Any post-approval change triggers resubmission, recalculation and reapproval.
Final decision
Move from a final number to the decisions underneath it.
Drill down from vehicle to part, process, material and supplier; compare periods; identify hotspots; and export the locked result with its audit trail.
Exploded footprint
L1 → L2 → L3 and process-level contribution, with the exact source and factor visible at every level.
Contribution by lifecycle source
Part-level drill-down
Interactive hierarchy and analysis views
Expand the result from vehicle to L1, L2, L3 and process, then switch between supplier, material, process, resource and period views.

Hotspot opportunities
Prioritized by contribution, data confidence and realistic reduction levers.
Low-carbon steel specification
Seat frame · 31.8 kg CO₂e contribution
Potential reduction per assembly from higher recycled content and EAF-based supply.
Renewable electricity coverage
Foam moulding and final assembly
Potential reduction by increasing verified renewable electricity from 23% to 70%.
Tier 2 load consolidation
Hosur → Chennai inbound route
