H&M scores 5 points higher than Primark on SINK's sustainability index.
H&M is more sustainable according to SINK's open sustainability index, scoring 40/100 vs Primark's 35/100 — a difference of 5 points.
H&M scores 40/100 on the SINK sustainability index (Below expectations). H&M has cut operational emissions 41% since 2019 and secured strong renewable energy commitments, but total supply chain emissions rose 3% year-on-year in 2024 despite headline 24% reduction claims. The fundamental fast-fashion model—1.5 billion items annually—remains linear. Multiple credible investigations link H&M to deforestation and greenwashing.
Primark scores 35/100 on the SINK sustainability index (Below expectations). Primark has built credible operational emissions reporting with 71% Scope 1&2 reductions, but total value chain emissions fell only 5.7% against a 50% 2030 target—pace is inadequate. Supply chain measurement is comprehensive but reduction lags. A Dutch court found its sustainability claims misleading. Fast fashion fundamentals remain unaddressed.
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.
