Rightmove has built a clean environmental record with SBTi-validated net-zero targets and comprehensive Scope 1, 2, and 3 emissions reporting. As a pure digital platform, its operational footprint is negligible. Weaknesses: no confirmed year-on-year absolute reduction delivery yet, minimal supply-chain engagement detail, and absent renewable energy percentage disclosure.
Rightmove scores 62/100 (Leading practice) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified May 2026.
That places Rightmove joint 10th of 847 companies scored, and 5th of 76 in SaaS / Digital Services.
