Supplier low-carbon electricity share against the local grid

A renewable percentage means little without the grid behind it. Sixty per cent low-carbon electricity is strong on a coal-heavy grid and ordinary on a hydro-heavy one, so a single threshold for every supplier rewards geography.

The grid comparison removes that. The Energy Map colours every country in five bands by its grid's low-carbon share, and each supplier row carries a marker for ahead, at or behind. The drawer gives it in one line: the organisation's share, the grid's share and the result.

Low-carbon here means renewable plus nuclear. Where an organisation discloses only a renewable share, that figure stands in and is flagged as assumed, so a supplier is never credited with more than it has published.

The marker also decides what happens next. A supplier ahead of its grid is a candidate to showcase, and one behind it with full disclosure is a candidate for renewable procurement. On the organisation's profile, the same grid line runs across the yearly electricity chart.
