Verify the footprint periodically and independently because a CO2 baseline is only useful when it remains reliable over time. Emission factors, project data, procurement choices and organisational boundaries can change, so the footprint needs maintenance and review.
In the Dura Vermeer CSRD context, verification supports both credibility and learning. It helps prevent one-off reporting and turns the footprint into a management instrument. Periodic checks make assumptions explicit, improve data quality and show whether reduction measures are actually moving the organisation in the right direction.
