Interpretation

Energy readiness scoring weighs policy clarity, building efficiency, and grid resilience. London's depth in policy is a strength; the building stock is the main lever. Across the indexed cities the energy average is 82/100, so London is close to the median for this dimension. Data year 2025; last updated 2026-05-05. Drawn from 3 institutional references.
