GRI 102 Scope 3 Reporting: Categories, Data Hierarchy and Supplier Estimates

GRI 102: Climate Change 2025 requires gross Scope 3 emissions to be reported by each of the 15 GHG Protocol categories, together with the consolidation approach, methods, assumptions, emission-factor sources and relevant base-year information. A first-year reporter should therefore screen every category, calculate material or high-priority categories with the best available data, use transparent estimates for the rest, and record a time-bound improvement plan.

How an LRA guide is built

Every answer follows the same discipline.

You should be able to stop reading after the first paragraph and still have what you came for. Everything below it exists so you can defend the answer to a reviewer.

  1. 01
    Answer

    The question is stated as a reporting team would ask it, and settled in the opening lines.

  2. 02
    Basis

    The official source and edition are named, and kept clearly apart from our reading of them.

  3. 03
    Judgement

    The points the standard leaves open are marked, with what a defensible position looks like.

  4. 04
    Action

    The answer links to the disclosures and evidence it affects, so a decision turns into fields to fill.

  • Practitioner-written, then technically reviewed
  • A named reviewer, with a date
  • Requirements kept separate from practice and interpretation
  • Stated update triggers for re-reading each answer

Coverage

Which frameworks have answers yet.

The guides tier is written framework by framework rather than thinly across all of them, so this says where the writing has actually reached. Disclosure cards, which cover the requirements themselves, run ahead of it.

Found the answer?

Turn the decision into a disclosure.

An answer settles what to do. The disclosure card is where it becomes data to collect, owners to name, evidence to retain and wording to draft — and when the whole reporting cycle is the problem, the programme walks it with a mentor on your own data.

Available as Guided Flex, Live Cohort, 1:1 Expert Mentorship or Corporate Programme.
