CO2e is carbon-dioxide equivalent, a unit used to express the warming effect of different greenhouse gases on a comparable basis.
What it means in a workplace context
Carbon footprints may present results in kilograms or tonnes of CO2e using recognised conversion factors.
Why it matters
The unit enables aggregation but does not remove the need for a defined boundary and method.
Questions to ask
- What decision or requirement does CO2e support?
- Which evidence or record is required?
- Who owns the information and keeps it current?
- How does it affect furniture selection, service or future change?
Applying the concept
When CO2e is used in reporting or supplier communication, state the boundary, period, methodology and source. Keep original evidence and distinguish verified facts from estimates or commitments.

Using the term in procurement
When CO2e appears in a procurement document, explain what suppliers must provide and how the response will affect evaluation. Avoid requesting evidence that is not used in the award decision, and distinguish mandatory requirements from preferred information.
After delivery, verify that promised documents, services or product information were supplied. A controlled handover and clear ownership make the term operational instead of leaving it as wording in the original quotation.
