Why It Matters: Rethinking Scope 3 for Travel
Still Using DEFRA? It’s Time to Upgrade.
Many organizations still rely on DEFRA emission factors for calculating business travel emissions, but these generalized averages often overestimate actual impacts — especially in aviation. DEFRA factors apply broad assumptions that don’t account for the most important of variables like aircraft type. This can lead to inflated and skewed Scope 3 figures and unnecessary mitigation costs.
Our aircraft-specific method uses real-world emissions curves tied to flight details (e.g., date, ticket number), offering up to 20–25% lower emissions estimates. This approach has been validated through a third-party GHG audit conducted for major consulting firms, ensuring credibility and compliance with evolving sustainability standards.
