Data completeness: 91% of boundary items evidencedFactor Sets: DESNZ 2026 (UK) & SEAI 2026 (Ireland)

Avoided Travel Emissions (Virtual Attendance Counterfactual)

~1.24 t CO₂e avoided

Invariant BR-062 Enforced: Calculated based on 115 registered virtual delegates who did not travel. In strict accordance with GHG Protocol and EU anti-greenwashing standards, avoided emissions are reported separately as a positive counterfactual and are NEVER subtracted or netted from the event's gross footprint.
