Sky has delivered measurable absolute emissions reductions (40% since 2018) backed by SBTi validation and third-party assurance on Scope 1&2 data. Strengths include RE100 membership, 92% renewable electricity, and a reduction-first approach. Weaknesses: Scope 3 lacks external verification, water impact unreported, and no executive compensation tied to sustainability targets.
