Edinburgh Napier University scores 52/100 (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 Edinburgh Napier University joint 96th of 780 companies scored, and joint 27th of 66 in Higher Education / Universities.

Edinburgh Napier has achieved substantial operational emissions reductions (49% absolute since 2018/19) and maintains transparent public reporting via HESA. However, Scope 3 emissions lack quantified year-on-year tracking, renewable energy covers only 28% of grid supply, and science-based target validation is absent. No fossil fuel controversies, but sustainability ambition is constrained by incomplete supply chain accountability.
