BT Group plc scores 2 points higher than Vodafone Group Plc on SINK's sustainability index.
BT Group plc is more sustainable according to SINK's open sustainability index, scoring 55/100 vs Vodafone Group Plc's 53/100 — a difference of 2 points.
BT Group plc scores 55/100 on the SINK sustainability index (Making progress). BT Group demonstrates industry-leading climate ambition with SBTi-validated 1.5°C targets and verified operational emissions cuts of 55% since 2017. Scope 3 reporting is comprehensive but reductions lag targets. Critical weakness: nature and biodiversity impact remains largely unquantified with no formal TNFD disclosure or deforestation commitments.
Vodafone Group Plc scores 53/100 on the SINK sustainability index (Making progress). Vodafone has built credible near-term climate targets validated by SBTi and achieved major operational emissions cuts (84% below FY20). Its Scope 3 reporting is granular but inconsistent—declining in FY25 partly through asset sales, not decarbonisation. Nature disclosure remains skeletal; trade association climate alignment is unreviewed.
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.
