CERs Index Methodology

    Four perspectives on corporate carbon reduction

    CERs Index uses public climate, financial, governance, and assurance information to assess corporate carbon-reduction performance.

    What we assess

    We assess actual emissions reduction, target delivery, capital allocation, and data credibility together.

    How the index is structured

    The four KPIs contribute equally to the final CERs Index.

    KPI 1

    Actual carbon reduction

    Did emissions actually fall?

    • E1 · Scope 1 & 2 performance
    • E2 · Scope 3 performance
    KPI 2

    Targets and delivery

    Are targets sound and being delivered?

    • T1 · Target design
    • T2 · Delivery progress
    KPI 3

    Capital allocation

    Are resources aligned with transition?

    • C1 · Green CAPEX
    • C2 · Low-carbon revenue
    • C3 · Internal carbon price
    • C4 · Climate-linked pay
    • C5 · Carbon-credit use
    KPI 4

    Data credibility

    Can the evidence and results be trusted?

    • R1 · Information completeness
