Grey-Fleet Cost & Carbon Calculator

Put a number on what staff using their own cars really costs (reimbursement, admin and CO2) and see what a shared pool, owned or leased, would save.

What's inside

  • Work out your true grey-fleet cost per mile, including hidden admin
  • Estimate the CO2 attached to grey-fleet mileage for net-zero reporting
  • Model the saving from shifting miles onto a shared pool
  • A one-page summary you can put in front of finance or committee
