Microsoft scores 1 point higher than Alphabet Inc. (Google) on SINK's sustainability index.
Microsoft is more sustainable according to SINK's open sustainability index, scoring 43/100 vs Alphabet Inc. (Google)'s 42/100 — a difference of 1 points.
Microsoft scores 43/100 on the SINK sustainability index (Below expectations). Microsoft reports comprehensive emissions data with third-party verification, but absolute emissions rose 23.4% since 2020 despite renewable energy claims. The company relies heavily on carbon removal credits to offset rising Scope 3 emissions, faces greenwashing accusations for marketing AI to fossil fuel companies while sponsoring climate events, and maintains trade association memberships actively opposing climate policy.
Alphabet Inc. (Google) scores 42/100 on the SINK sustainability index (Below expectations). Alphabet's emissions have risen 51% since 2019 despite renewable energy PPAs, driven by explosive data center expansion for AI. The net-zero 2030 target is implausible: absolute emissions climb, Scope 3 surges 22% annually, and the company has reframed targets as 'moonshots.' Greenwashing concerns are credible.
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.
