York St John University scores 56/100 (Making progress) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified September 2026.

That places York St John University joint 31st of 780 companies scored, and joint 4th of 66 in Higher Education / Universities.

York St John has cut Scope 1+2 emissions 67.5% since 2005 and publishes statutory data via HESA. Scope 3 reporting is skeletal—only commuting quantified, no supplier engagement. Energy comes from named PPAs and on-site solar, but renewable percentages lack HESA confirmation. Biodiversity outcomes are credible; nature supply-chain risk unmapped.
