Reddit scores 35/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified May 2026.

That places Reddit joint 466th of 809 companies scored, and joint 48th of 75 in SaaS / Digital Services.

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.
