St Mary's has cut operational emissions 52% since 2005 and recycles 97.9% of waste—genuinely strong numbers for a small campus university. But renewable energy sourcing is absent entirely, Scope 3 reporting has lapsed, and science-based targets are missing. The university acts where it counts operationally but lacks the supply chain rigour and ambition required for a higher band.
