Nestlé scores 5 points higher than Unilever on SINK's sustainability index.
Nestlé is more sustainable according to SINK's open sustainability index, scoring 35/100 vs Unilever's 30/100 — a difference of 5 points.
Nestlé scores 35/100 on the SINK sustainability index (Below expectations). Nestlé discloses comprehensive climate data with SBTi validation and 18.6% gross emissions reduction, but relies on eightfold scaling of uncertain nature-based removals to hit 2030 targets. Packaging recyclability commitments were quietly weakened in 2022 to 'designed for recycling'; greenwashing lawsuits are pending. Supply chain water and regenerative sourcing remain materially underdeveloped.
Unilever scores 30/100 on the SINK sustainability index (Significant gaps). Unilever reports granular climate data with third-party verification, yet total emissions rose 3% in 2024 while Scope 3 dominates at 99% of the footprint. Trajectory misses SBTi targets by 45%. Multiple greenwashing investigations and weakened targets (plastics, biodiversity) undermine credibility despite renewable energy progress and deforestation commitments.
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.
