Our verdict

Reddit is a $2.2B public company with zero environmental commitments, no emissions reporting, and complete non-disclosure across sustainability metrics. As a rapidly scaling digital platform (69% revenue growth, 46% user growth), its energy consumption is rising unmeasured. No climate targets, no renewable energy strategy, no supply chain oversight—only silence.

Reddit scores 35/100 (Below expectations) on SINK's independent climate assessment, scored from public data only. Scores are free. Companies can never pay for anything about their own score. Last verified May 2026.

That places Reddit joint 540th of 934 companies scored, and joint 43rd of 73 in SaaS / Digital Services.

Limited evidence. This score rests on 4 sources, 25% of them published by the company itself. Every source cited here passed the same quality checks as any other score: all live, none from data aggregators. There is simply less of it.

The ten questions

What is Reddit doing well, and where does it fall short?

Strongest on Controversies & Red Flags and Nature & Biodiversity Impact (8/10, 3/10). Weakest on Targets & Commitments and Transparency & Accountability (0/10, 0/10).
