Meta Platforms scores 3 points higher than Alphabet Inc. (Google) on SINK's sustainability index.
Meta Platforms is more sustainable according to SINK's open sustainability index, scoring 46/100 vs Alphabet Inc. (Google)'s 43/100, a difference of 3 points.
Meta Platforms scores 46/100 on the SINK sustainability index (Making progress). Meta matches its electricity with renewable power purchases, but its location-based Scope 2 has risen nearly 150% since 2019 and it left RE100 in 2026 over new gas power for AI data centres. Its Scope 3 target is a cap at the 2021 level rather than a cut, and as an advertising platform it is exposed to fossil-fuel advertising, a point flagged for review.
Alphabet Inc. (Google) scores 43/100 on the SINK sustainability index (Below expectations). Alphabet's emissions rose 18% in 2025 to 18.8 Mt CO2e, driven by data-centre growth, and Scope 3 rose 25% year on year. Its near-term target is a 50% absolute cut by 2030, which Google's own report says the SBTi validated in 2025, but emissions on its own ambition basis are 81% above 2019 and the plan leans on carbon removals and certificates.
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.
