The Framework Concept Behind the DEISO LCA Data Collection System™

The DEISO LCA Data Collection System™ is built on a structured, logic-driven framework designed to transform how Life Cycle Assessment (LCA) data is collected, organized, and validated. Rather than treating data collection as a fragmented or ad hoc process, the system establishes a clear methodological architecture aligned with ISO 14040 and ISO 14044 principles.

From Fragmented Data Collection to Structured LCA Architecture

Traditional LCA data collection often suffers from inconsistent formats, unclear system boundaries, and repeated communication cycles between consultants and clients. This framework addresses these issues by introducing a predefined structure that enforces clarity, consistency, and traceability across all life cycle stages.

Core Structural Logic: Cradle – Use Phase – Grave

The framework is built around a clear separation of life cycle stages, ensuring that all data is captured in the correct context:

• Cradle: Raw material extraction, upstream processing, inbound transport, and manufacturing activities before the product leaves the factory gate.
• Use Phase: Operational use, maintenance, energy consumption, and functional performance over the product lifetime.
• Grave: End-of-life activities including collection, transport, recycling, waste processing, and final disposal.

Functional Separation of Data Across Sheets

Each sheet within the system represents a specific function within the LCA workflow. This separation ensures that:

• Material data is captured independently from manufacturing processes
• Transport is isolated as a cross-cutting activity across life cycle stages
• Use phase assumptions are clearly defined and traceable
• End-of-life scenarios are structured and not mixed with operational data

Key Principle: Data Must Be Placed Where It Occurs

The framework enforces a strict rule: each dataset must be recorded in the sheet corresponding to the actual life cycle stage in which it occurs. This eliminates ambiguity and improves both model accuracy and audit readiness.

Product-Centric Data Integration

The system is designed around a Product ID logic, enabling consistent data linkage across all sheets. This allows:

• Seamless integration of data across cradle, use, and grave stages
• Support for both single-product and comparative LCA studies
• Improved traceability and validation across datasets

Embedded Intelligence Layer

Beyond structure, the framework integrates a logic layer that enhances data reliability:

• Validation rules to detect missing or inconsistent entries
• Completeness tracking to monitor data readiness
• Standardized input formats using dropdown-driven workflows
• Comparative logic to support multi-product analysis

Designed for Real-World LCA Workflows

This framework is not theoretical. It is designed to operate in real consulting, industrial, and research environments where data quality, consistency, and time efficiency are critical. By combining structural clarity with embedded intelligence, the DEISO LCA Data Collection System™ transforms data collection into a controlled, scalable, and professional process.
