Tritax Big Box REIT scores 32/100 (Below expectations) on SINK's independent climate assessment — scored from public data only, no company payment can change a number. Last verified October 2026.

That places Tritax Big Box REIT joint 533rd of 809 companies scored, and 15th of 20 in Construction / Real Estate.

Tritax Big Box discloses landlord emissions rigorously but excludes the material occupier footprint—material supply-chain carbon remains unmeasured. Intensity improvements mask flat absolute reductions. Solar expansion is real; full Scope 3 disclosure deferred to June 2025. Targets lack SBTi validation. Clean governance and no controversies.
