You only need to include data on transport that your company operates, e.g: Fuel used in company cars on business use Fuel used in fleet vehicles which you operate on business use Fuel used in personal/hire cars on business use Fuel used in private jets, fleet aircraft, trains, ships, or drilling platforms which your organisation operates. If your employees take trains, flights or taxis for business use, that are not operated by the company, then you don’t need to report on these. You also don’t need to report on fuel used by subcontractors in transporting goods. For advice on how to start gathering transport data, read our guide.
