How to use each sheet in the DEISO LCA data collection system
The table below explains the purpose of each sheet and how to use it correctly within the cradle-to-grave LCA workflow.
| Sheet name | Purpose | How to use |
|---|---|---|
| Copyright | Defines DEISO ownership, template identity, and legal notice. | Review this sheet first. Do not modify legal content when sharing externally. |
| Framework_Overview | Explains the ISO 14040/14044 cradle-to-grave logic of the system. | Read before data entry to understand structure and relationships between sheets. |
| Cradle | Guides how to allocate upstream, material, and manufacturing data. | Use as a reference when deciding whether data belongs in BOM_Packaging, Manufacturing, or Logistics. |
| Project_Setup | Defines study scope, functional unit, and system boundary. | Complete first. Confirm all inputs are aligned with the functional unit before proceeding. |
| Product_Portfolio | Defines products for single or comparative LCA. | Assign a unique Product ID and reuse it across all sheets. |
| BOM_Packaging | Captures raw materials, components, packaging, and upstream sourcing. | Enter material data linked to Product ID and functional unit. Include origin, supplier, and data source. |
| Manufacturing | Captures factory processes, energy use, emissions, and waste. | Use for all operations within the factory gate. Record processes, inputs, outputs, and losses. |
| Logistics | Captures transport across cradle and grave stages. | Separate inbound transport, distribution, installation, and end-of-life transport clearly. |
| Use Phase | Captures product use, maintenance, energy, and operational inputs. | Define realistic use scenarios, lifetime assumptions, and consumption patterns. |
| End_of_Life | Captures disposal, recycling, and waste processing logic. | Define treatment pathways, recycling rates, and final disposal scenarios. |
| Grave | Explains how to interpret end-of-life data blocks. | Use as a guidance sheet to correctly assign data between End_of_Life and Logistics. |
| Dashboard | Provides completeness tracking and data quality visibility. | Monitor progress, identify missing data, and review overall data readiness. |
| Comparison | Compares multiple products for data completeness and structure. | Use for comparative LCA setup and to check consistency across products. |
The framework concept behind the DEISO LCA data collection system
The DEISO LCA Data Collection System is built on a structured, logic-driven framework that changes how Life Cycle Assessment 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 those issues with a predefined structure that holds clarity, consistency, and traceability across all life cycle stages.
Core structure: cradle, use phase, grave
The framework separates life cycle stages so 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 represents a specific function within the LCA workflow. That separation means:
- 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
Data must be placed where it occurs
Each dataset must be recorded in the sheet corresponding to the actual life cycle stage in which it occurs. This removes ambiguity and improves both model accuracy and review readiness.
Product-centric data integration
The system is built around a Product ID logic, giving consistent data linkage across all sheets. This supports:
- Data that connects cleanly across cradle, use, and grave stages
- Both single-product and comparative LCA studies
- Stronger traceability and validation across datasets
Embedded intelligence layer
Beyond structure, the framework integrates a logic layer that strengthens 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
Built for real-world LCA workflows
This framework is not theoretical. It is built to operate in real consulting, industrial, and research environments where data quality, consistency, and time efficiency are critical. By combining structural clarity with an embedded logic layer, the DEISO LCA Data Collection System turns data collection into a controlled, scalable, professional process.
