    Renewable energy share

    Formula

    Renewable energy share

    Renewable Energy Share (%) = Energy from renewable sources ÷ Total energy consumed × 100

    Variables

    Energy from renewable sourcesRenewable electricity, fuel and other renewable energy consumed, in gigajoules
    Total energy consumedAll energy consumed from renewable and non-renewable sources, in gigajoules

    Finding the inputs

    BRSR Principle 6 splits energy into renewable and non-renewable sources (a BRSR Core indicator). Some companies also report the renewable share of electricity alone.

    Reading the number

    Separate two figures: the renewable share of total energy, and the renewable share of electricity. Many industrial companies use far more energy as fuel than as electricity, so a high renewable electricity share can still mean a low renewable share of total energy. Also check how renewable electricity was obtained: own plants and direct contracts are stronger evidence than unbundled certificates.
