# Whether a confirmed baseline has drifted from the ledger

`GET /net-zero/baselines/{baselineId}/recalculation`

Compares each scope of the baseline's snapshot with the ledger's figures for the same period today. required is true when any scope has moved by 5% or more (the SBTi recalculation trigger). Scopes the baseline replaced by hand are not compared. Requires org.view_dashboard.

## Path parameters

- `baselineId` string, uuid, required

## Response `200`

Drift per scope

- NetZeroRecalculationResponse
  - `data` object, required
    - `baselineId` string, uuid, required
    - `required` boolean, required
    - `scopes` NetZeroRecalculationScope[], required
      - `baselineKgCo2e` number, double, nullable, required
      - `currentKgCo2e` number, double, nullable, required
      - `driftPct` number, double, nullable, required — Current minus baseline over baseline (0.1 = +10%); 1 when a scope with no base-year figure now has one.
      - `notComparable` boolean, required — Scope 2 confirmed before dual reporting summed both methods, so it is not compared with today's location-based figure.
      - `replaced` boolean, required — The baseline replaced this scope by hand, so the ledger is not compared.
      - `scope` integer, required
    - `threshold` number, double, required
