The gap between the business carbon performance and its sector median, as a ratio. The lower, the better.
Why this indicator
Carbon performance is both a normative constraint issue and a long-term productivity issue: in the immediate term, large emitters must pay taxes on their externalities, and over the long term they contribute to the degradation of everyone's working environment.
The gap is calculated against the sector medians declared in public references.
Where to find the figure
