Where the uncertainty lives
Small category, briefly: the largest σ contribution is pawston event-day staff commute to venue at ± 85 kgCO₂e (14.5% σ). With only 14 staff the activity data is essentially complete; the band you see is the employee-commute mode mix — DEFRA's UK-average rail+metro factor blends modes whose intensities differ by ~3× and that blend is where the σ sits, not in the headcount.
