# Which energy line does the Higg Facility Environmental Module (Higg FEM) want for pet coke, furnace oil and kerosene?

Canonical: https://senseible.earth/answers/higg-fem-petcoke-furnace-oil-which-energy-line

Report pet coke under coal, and furnace oil or kerosene under the blended fuel oil line. The Higg FEM guide says so in its energy notes. Enter tonnes or litres as billed. The form turns them into energy and emissions itself, so do not convert them first.

## The two lines the guide names

- Coal, commercial mix: the guide says it includes all types of traditional coal, for example anthracite and bituminous. It also says petroleum coke should be reported under coal, because on an energy basis pet coke and coal are very similar, with pet coke having a slightly higher emission factor.
- Fuel Oil, Blended: the guide says it includes all types of fuel oils, for example furnace oil, bunker fuel and kerosene.

## Our reading, not the guide's

Because the guide says pet coke has a slightly higher emission factor, the coal line probably gives a slightly lower figure than pet coke's own factor would.

## What the form does with your tonnes

An emission factor is a conversion number, like a market rate per kilo that turns weight into rupees. The form first turns your quantity into megajoules (MJ) of heat. Think of it as asking how much heat a kilo of that fuel gives. It then multiplies by its own factor.

In Cascale's FEM 2024 calculations paper, coal is 24.8766 MJ a kilogram at 0.0950 kilograms of carbon dioxide equivalent (CO2e) per MJ. Fuel oil is 46.1209 MJ a kilogram, or 38.7416 MJ a litre, at 0.0778 kilograms of CO2e per MJ. Check that the 2026 form has not changed these.

## What to keep for the verifier

- Purchase invoices with the quantity and unit, and any meter or weighment records. The guide lists energy purchasing and use records, for example invoices and metering records.
- A stock register that ties opening stock plus purchases, less closing stock, to the quantity used. This is our suggestion, not a Cascale requirement.

## 300 tonnes of pet coke and 100 tonnes of furnace oil in a year

- Pet coke, entered as coal: 300,000 kilograms x 24.8766 = 7,462,980 MJ; x 0.0950 = 708,983 kilograms, about 709.0 tonnes of CO2e
- Furnace oil, entered as fuel oil: 100,000 kilograms x 46.1209 = 4,612,090 MJ; x 0.0778 = 358,821 kilograms, about 358.8 tonnes of CO2e
- Together: 709.0 + 358.8 = 1,067.8 tonnes of CO2e

Tonnages are an example. Energy and emission figures are the FEM 2024 paper's own; the form's current table may differ.

## What Senseible does here

Senseible reads fuel invoices and electricity bills into monthly records, so coal and furnace oil bought each month are totalled; pet coke bills are kept as records. The self-serve product does not enter anything into the Higg FEM; you fill it in on Worldly.
