# AI for Taxonomy and Unit Harmonization in LCA: Clean Messy Data in Minutes

> A practical playbook to standardize names, map processes, and fix units with AI so your sustainability data stays consistent, traceable, and auditable.

Messy spreadsheets can quietly break sustainability accuracy. “SS 18/8”, “stainless304”, and “steel austenitic” might mean the same thing; kWh and MJ get swapped; distances appear in miles.\
**AI can clean and standardize this chaos in minutes** — harmonizing names, mapping to the right datasets, and fixing units automatically so teams can focus on insight, not cleanup.

<Info>
  **Sustainly’s transparent AI copilot** makes taxonomy and unit harmonization fast, auditable, and scalable — keeping your sustainability data consistent across projects and teams.

## What To Standardize

* **Taxonomy:** unify material and process names into canonical terms (e.g., “stainless steel 18/8”).
* **Units:** convert and align measurement systems (g→kg, miles→km, BTU→MJ, L→m³).
* **Metadata:** ensure regional, temporal, and technology qualifiers are properly defined.
* **Sources:** differentiate between primary, secondary, reported, or inferred data.

***

## 5-Step Harmonization Flow

1. **Collect datasets** — from BOMs, utilities, transport, and packaging data.
2. **Detect conflicts** — find duplicates, mixed units, or missing regional data.
3. **Suggest canonical terms** — AI proposes matches, and you review or approve.
4. **Map to background datasets** — ensure regional and technological alignment.
5. **Lock a dictionary** — create a reusable “golden mapping” applied to future imports.

**In Sustainly:** AI-assisted mapping and automated unit harmonization run instantly; you simply review exceptions to maintain full transparency and control.

***

## Canonical Dictionary (Starter)

* `stainless 18/8` → `Stainless steel, austenitic 18/8 (EU, 2024)`
* `cardboard` → `Paperboard, recycled content 80% (EU)`
* `truck med` → `Transport, freight, 16–32 t, EURO6 (EU)`

Keep this canonical dictionary versioned (JSON/YAML) and reuse it across projects for consistency.

***

## Validation Checks To Enable

* **Unit guardrails:** reject unknown unit strings; enforce SI base units.
* **Range checks:** ensure plausible energy or material intensity (e.g., 0.1–20 kWh/unit).
* **Region gates:** restrict or flag datasets outside the target geography.
* **Completeness:** confirm all modules or stages are represented before assessment.

***

## Handling Edge Cases

* **No exact dataset match:** select the nearest technology and document uncertainty.
* **Mixed-year data:** normalize to the study year or flag sensitivity.
* **Supplier synonyms:** maintain an alias list so future imports map automatically.

***

## Audit & Traceability

* Save a **mapping report** — detailing old vs. new names, reasoning, and reviewer notes.
* Store **unit conversion factors** and their data sources.
* Maintain an **exceptions log** for verifier or auditor review.

> ✅ Sustainly’s centralized data system ensures every mapping, conversion, and revision stays transparent and reusable across your organization.

## FAQ

**Will AI ever map incorrectly?**\
Occasionally — review regional and technological context before finalizing.

**Do I need to manage databases manually?**\
No. Sustainly’s AI harmonization works across standardized datasets, letting you focus on results rather than configuration.

**How do I keep mappings updated?**\
Version your dictionary and review quarterly — updates apply automatically across imports.
