Pending reviewMixed evidence· 10 src

Limited evidence. Published with 2 independent parties, below our full-confidence threshold of 3. Every source cited on this page passed the same quality checks as any other score: all live, none from data aggregators. There is simply less of it.

Telefónica has delivered substantial absolute emissions reductions—84.8% in operations, 31.3% in supply chain since baseline years—backed by SBTi validation and 11 consecutive CDP A-List recognitions. Weaknesses: Scope 3 still dominates the footprint at 91%, biodiversity strategy remains incomplete, and trade association memberships (BusinessEurope, CEOE) misalign with stated climate ambition.

Telefónica scores 54/100 (Making progress) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.

That places Telefónica joint 64th of 847 companies scored, and joint 2nd of 18 in Telecommunications.
