Score breakdown

Resource efficiency

88

Resource efficiency is about grid build-out, operational footprint, and procurement discipline. The 2025 package is report-grade enough to support evidence-weighted scoring.

Impact on environment

93

Environmental performance is best judged through a stable disclosure surface. Iberdrola’s 2025 sustainability report is explicit enough to audit claims over time.

Social responsibility

87

Renewables social outcomes depend on communities, workforce, and governance for transition impacts. The report provides usable disclosure structure, with the normal limits of comparability across geographies.

Economic benefits

92

The economic signal is whether sustainability is embedded into long-run capital discipline and grid / renewable execution, not treated as a parallel CSR layer.
