Our factory's diesel tank also fuels our trucks. How do I report that in the Higg Facility Environmental Module (FEM) without counting it twice?
Report each litre once. The Higg FEM asks first for factory energy sources excluding company owned and controlled vehicles, then separately for those vehicles. Fuel for vehicles refuelled onsite goes in the vehicle section only if you track it separately and have subtracted it from the factory total for that fuel.
What counts as a company vehicle
The guide says owned or controlled means any vehicle the facility owns or has operational control over, for example a leased vehicle the facility uses. It covers vehicles that carry employees, contractors, customers, raw materials or product.
The rule against counting twice
The same note appears under the question that asks for quantities: do not report onsite vehicle fuel there unless it has been subtracted from the facility total.
- For fuel put into vehicles at your site, select it only if its use is tracked separately and is not already in the factory total for that fuel.
- Electric vehicles charged onsite from purchased electricity: do not select electricity for vehicles unless that use is tracked separately and subtracted from the factory electricity total.
- Gas or propane vehicles refuelled onsite and not tracked separately: do not select them as vehicle sources either.
Fuel blends
If you select diesel, biodiesel, ethanol or petrol for vehicles, the module asks for the blend. If petrol is 90% petrol and 10% ethanol, enter 10 for the ethanol share. The guide says to get this from your fuel provider, and names B10 (10% biodiesel in diesel) and E85 (up to 85% ethanol in petrol). The guide also writes E10, E15 and E20 as examples of petrol blends, meaning 10, 15 and 20% ethanol in petrol.
How you are scored
The question that asks whether you track every vehicle fuel gives full points for Yes and partial points if you track at least one. For each fuel you give the quantity, the unit, how you tracked it and any comments. Annual totals in a spreadsheet are fine if the detailed records are available when asked.
One diesel tank, example numbers
- Diesel bought in the year for the site: 30,000 litres
- Fuel dispensed to two company trucks, from the pump log: 12,000 litres
- Vehicle section: 12,000 litres. Factory section: 30,000 minus 12,000 = 18,000 litres, for the generator and boiler
- Together: 18,000 + 12,000 = 30,000, the same as bought, so no litre is counted twice
Numbers are examples. The pump log is what lets you subtract; without a separate log, leave all 30,000 litres in the factory section and do not select diesel for vehicles.
What Senseible does here
Senseible reads fuel invoices and electricity bills into monthly records, so the diesel purchased is easy to see. The split between trucks and the generator needs your own pump log.
