Apple Inc. scores 12 points higher than Samsung Electronics on SINK's sustainability index.
Apple Inc. is more sustainable according to SINK's open sustainability index, scoring 40/100 vs Samsung Electronics's 28/100, a difference of 12 points.
Apple Inc. scores 40/100 on the SINK sustainability index (Below expectations). Apple's total emissions fell from 23.2 Mt in FY2021 to 15.3 Mt in FY2025 but were flat from FY2024 to FY2025, and product-related Scope 3 rose in FY2025. Product manufacturing is the largest source at 8.15 Mt. A Frankfurt court barred 'CO2-neutral' Apple Watch advertising in 2025, and its carbon-neutral claims rely partly on avoidance credits.
Samsung Electronics scores 28/100 on the SINK sustainability index (Significant gaps). Samsung discloses emissions comprehensively but is failing to reduce them. Operational emissions rose 7.8% in 2024; total emissions including supply chain increased despite net-zero rhetoric. The company's 2050 net-zero target covers only 16% of emissions and lacks SBTi validation. Unvalidated targets, late Scope 3 disclosure, and planned massive semiconductor expansion undermine credibility.
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.
