Stranding risk — CRREM pathway
Year each building's flat-to-current trajectory crosses the CRREM 1.5°C UK office pathway
What the chart shows
At 33.6 kgCO₂e/m² the building is already at or past the CRREM 1.5°C anchor for 2025. The Old Exchange holds until ~2035; Riverside Court ~2042 — though that figure assumes the benchmark-estimated tenant energy is correct, which the data-coverage flag warns against.
Portfolio-weighted by floor area: ~27.5 kgCO₂e/m². Pawston House dominates the weighting and is already at or past the 2025 anchor of the CRREM 1.5°C UK office pathway.
Pathway vs asset trajectories
Stranding year by building
| Building | Current kgCO₂e/m² | Stranding year | CI95 | Status |
|---|---|---|---|---|
| Pawston House | 33.6 | 2025 | 2024–2026 | Stranded now |
| The Old Exchange | 11.2 | 2035 | 2033–2037 | Strands before 2035 |
| Riverside Court | 5.2 | 2042 | 2039–2046 | Aligned through 2035 |
Stranding year = first year the flat-to-current trajectory crosses the CRREM 1.5°C pathway. CI95 reflects the σ band on current intensity (the same uncertainty engine that produces the headline footprint band). Riverside Court's wide CI is a symptom of its rung-5 benchmark data, not climate uncertainty.
