How do we count diesel used by a concrete pump on site?
A truck-mounted or stationary concrete pump burns diesel at 2.68 kg CO2 per litre. If you own or run it, it is Scope 1. If a contractor brings and fuels it, it is their Scope 1 and your Scope 3. Divide litres by cubic metres pumped for a per-pour figure.
Records
- Litres filled per pump per day.
- Cubic metres poured, from delivery challans.
- Who supplied the fuel.
With ready-mix
Ready-mix suppliers often pump as part of the order. Ask whether their per cubic metre figure includes pumping, so it is not counted twice.
What Senseible does here
Senseible reads bills, fuel invoices and production records into dated, fingerprinted records, so the figure you send a buyer can be traced to its documents.
