Duolingo, Inc. (DUOL) — ESG & Values Scores

Environment story

Duolingo discloses minimal environmental data. No Scope 1, 2, or 3 emissions reporting identified in 10-K. No net-zero target disclosed. The company operates primarily as a software/SaaS business with cloud infrastructure hosted by AWS and Google Cloud; direct operational emissions are likely modest relative to typical industrial firms, but absence of disclosed metrics and targets limits full assessment. No material environmental controversies (toxic waste, water, habitat) detected in available documents. Scoring reflects lack of verified decarbonization commitments and absence of emissions transparency rather than evidence of poor environmental practice.

Disclosed initiatives

Cloud Infrastructure Reliance

Significant portion of product traffic, data storage, and processing hosted by AWS and Google Cloud; third-party providers' renewable energy usage not explicitly disclosed by Duolingo.

Social story

Duolingo discloses limited social responsibility metrics. No CEO-to-median-worker pay ratio, workforce turnover rate, or diversity percentages provided in 10-K. No documented union-suppression activities or major strikes reported in 24-month period. Company emphasizes mission-based commitment to free language learning access and global education equity. Headcount growth cited as ongoing priority, but specific labor practices, supply-chain audits, and labor union standing not addressed in available filings. Human-capital-related activism mentioned as emerging concern but no specific controversies disclosed. Lack of comprehensive social disclosure limits full scoring.
