Grey Fleet
Employee-owned vehicles used for business travel
What is Grey Fleet?
The grey fleet consists of vehicles owned by employees but used for business purposes, for which the employee claims mileage expenses. Grey fleet emissions fall under Scope 3 (optional) for SECR purposes.
Why It Matters for SECR
Grey fleet can represent a significant emissions source and cost for organisations with mobile workforces. While voluntary under SECR, many companies choose to report it.
Examples
- 1
Sales representatives claiming mileage for client visits
- 2
Care workers driving between appointments
- 3
Home-to-work travel is not business travel
SECR Reporting Requirements
Not mandatory under SECR but commonly reported as part of Scope 3. Requires mileage data and appropriate conversion factors.
