Mitie has cut operational emissions over two years but weakened its climate targets after the Marlowe acquisition, switching from absolute to intensity-based goals and cutting Scope 3 reduction from 80% to 50%. Fleet electrification is substantial at 76%, offset by reliance on REGOs and carbon credits. Supply chain mapping remains patchy; nature and water disclosure are minimal.
Mitie scores 53/100 (Making progress) on SINK's independent climate assessment, scored from public data only. Fees pay for the review, never the result. Last verified October 2026.
