Vodafone Group Plc scores 9 points higher than BT Group plc on SINK.
Vodafone Group Plc is more sustainable according to SINK's scores, scoring 51/100 vs BT Group plc's 42/100, a difference of 9 points.
BT Group plc scores 42/100 on SINK (Below expectations). BT Group discloses operational emissions comprehensively with third-party assurance and has achieved 52% absolute Scope 1+2 reduction. But renewable energy coverage dropped to 53% after ditching dubious certificates, Scope 3 progress lags targets at 25% of 42%, and biodiversity—material given its vast UK infrastructure—remains unmeasured and below materiality threshold.
Vodafone Group Plc scores 51/100 on SINK (Making progress). Vodafone reports absolute Scope 1+2 cuts and SBTi-validated net-zero targets, but relies heavily on renewable energy certificates rather than physical PPAs. Scope 3 is modelled, off trajectory, and falling mainly through divestment. Nature, water, and circular economy disclosure remain minimal.
Both companies are rated on the same 10-question SINK rubric: Scope 1/2/3 carbon footprint, energy source, nature and biodiversity, resource use, water, emissions trajectory, science-based targets, transparency, and controversies. Scores are 0–100, based on public data, and fully reproducible.
