By using the Fuel Carbon Calculator, HMRC will establish the number of litres of fuel used to transport its mail and then calculate how it could reduce CO2 emissions by using HVO rather than diesel. Both parties benefit from the initiative as they can both reduce their carbon emissions: Whistl through using HVO reduces the CO2 it generates; and HMRC by reducing its CO2 impact under Scope 3* reporting.

The Fuel Carbon Calculator was launched in August 2024 and is the first of its kind in the Downstream Access Bulk Mail sector.

Nick Wells, Executive Chairman, Whistl, said: “Through using our innovative tool, large volume mailers such as HMRC can reduce the CO2 emissions in their supply chain. We are delighted that they have joined us on this important journey of reducing our impact on the environment and helping us both make progress on reaching our individual net zero goals.”

*Scope 3 encompasses emissions that are not produced by the company itself and are not the result of activities from assets owned or controlled by them, but by those that it's indirectly responsible for up and down its value chain.

Whistl is a £770+ revenue, delivery management company that provides mail, parcels, leaflet advertising, fulfilment and contact centre services in the UK and internationally. Headquartered in Marlow, the Whistl group of companies operate across the UK, and handles in excess of 3.6bn items a year.
