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 baseline despite 71% revenue growth. Heavy reliance on carbon removal credits, annual renewable matching that masks hourly grid reality, and membership in climate-obstructing trade associations undermine net-zero credibility.
Alphabet Inc. (Google) scores 42/100 on the SINK sustainability index (Below expectations). Alphabet's emissions are rising 51% above 2019 baseline despite renewable energy matching, with Scope 3 surging 22% annually. The company's 2030 net-zero target is unachievable on current trajectory. Reframing targets as 'moonshots' and adjusting Scope 3 boundaries signal weakening commitment, while AI infrastructure expansion drives water and material consumption higher.
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.
