Methodology

AI on a leash, by design.

Looper treats AI as a junior assistant, not an oracle. Every assessment runs inside a deterministic workflow — engineered gates, mandatory checkpoints, source-tagged data, full audit trail.

Six guardrails

Engineered guardrails the model can't talk its way out of.

  • Phase gates

    Mandatory STOP points where the user reviews and confirms before the assistant proceeds. The agent cannot skip ahead.

  • Quality thresholds

    Numeric guardrails (e.g. ≥80% confirmed material mapping before impacts are calculated) are written into the calculation engine, not just the prompt.

  • Anti-double-counting

    Cumulative LCIA vectors and dataset tracking prevent the most common LCA error — adding upstream impacts twice.

  • Unit safety

    Eight dimensional groups prevent nonsense conversions. You cannot accidentally convert kilograms into kilowatt-hours.

  • Audit trail by default

    Every mapping, assumption, and parameter change is recorded with a source label (user, ai_generated, assumption, web search) so a reviewer can always tell who decided what.

  • Defence-in-depth scope

    Supplier-scoped sessions are guarded at three independent layers — JWT, database row-level security, and the agent's tool-input validator. No single failure unlocks data.

Six method packages

The right standard, picked for you.

Each package bundles system boundary, allocation, biogenic carbon mode, and indicator set. The agent picks the package from your industry and goal — not from your manual config.

The standards aren't referenced in the report — they shape it.

Responsible AI

The compute side, engineered with the same care as the methodology.

  • Cost & turn caps

    Every session has a hard compute budget and a maximum number of turns. The agent cannot quietly run away or rack up unbounded cost.

  • Audit hooks

    Every tool call is validated before execution and logged after. Conversation history is append-only — turns can't be rewritten retroactively.

  • Multi-tenant isolation

    Customer data is row-locked at the database level. Session storage is scoped per user and per session, with time-limited access URLs.

  • Reproducibility

    Every assessment carries a stable identifier of the configuration that produced it. Re-running the same configuration produces identical numbers — meeting ISO 14040 reproducibility.

Six report formats

Every assessment ends in a downloadable PDF.

Server-rendered from structured calculation results, persisted with metadata for retrieval, exportable as native PDFs (and CSV/Excel extracts of the underlying tables).

ISO 14040/14044 + EN 15804 full study. Goal/scope/inventory/impact/interpretation. 11-column LCIA tables in scientific notation.
