QUICK ANSWER

What is the simplest way for a small steel mill to track its carbon emissions?

The simplest way for a small steel mill to track its carbon emissions is software built to work out Scope 1 and 2 from monthly energy records. Arc furnace and rolling mill power, reheating gas and mobile equipment diesel are set up once, then you add monthly quantities. GHG Metric keeps it plain on a GHG Protocol basis, with specialist help for electrode carbon.

Add the mill and pick grid electricity, reheating furnace gas, cranes and loaders, and any cooling equipment.

Enter each month's power in kWh, gas in m³ and diesel in liters from invoices and logs.

GHG Metric converts every quantity with a GHG Protocol factor and assigns it to Scope 1 or Scope 2.

Check which furnace or line ranks first and plan your next efficiency step around it.

Why Steel Production Carbon Emissions Are Hard to Count

Carbon in a steel mill arrives in power, gas and raw materials, and each melt shop uses them differently.

Carbon that enters as material, not fuel

Graphite electrodes, charge carbon, injected coal and carbonate fluxes release CO2 in the furnace even though they never appear on a fuel bill. Counting them needs your own consumption figures.

One power bill for melt shop and mill

The arc furnace, ladle furnace, rolling mill and fume extraction share a single grid connection. Without separate items, you can't tell whether melting or rolling deserves the next investment.

Heat logs, fuel logs and spreadsheets

Reheating furnace gas, forklift LPG and crane diesel are logged by different teams in different files. Closing the year means chasing months that were never entered.

Automotive and construction buyers ask for data

Car parts makers, rebar distributors and export customers ask steel suppliers for their direct and electricity emissions before renewing contracts, often with a short deadline.

How It Works

How to Calculate Steel Production Carbon Emissions in Your Mill

Describe the mill in the words your melt shop uses. Our specialists join for the process carbon part, and GHG Metric files every activity in its category.

Add the mill or rolling site

Create each melt shop, rerolling mill or finishing plant as a facility. Further sites can be added whenever the business grows.

Choose cards for furnaces and fleet

Select power and gas, LPG or fuel oil for preheating, cooling equipment, and mobile plant like forklifts, scrap handlers and slag carriers. Electrodes and charge carbon are configured with our team.

Name each furnace and meter once

Set up items such as "EAF electricity" in kWh, "Reheating furnace gas" in m³ or "Scrap handler diesel" in liters, and star them so they return each month.

Enter figures and read the ranking

Add the month's quantities from invoices, meter readings and fuel logs. The mill total, stacked chart and source ranking change the moment you save.

Platform Features

Calculate, Track and Reduce Steel Production Carbon Emissions

Shaped around arc furnaces, reheating furnaces and rolling lines, with specialist support where carbon enters as material.

Calculate Steel Mill Emissions From Power, Gas and Melt Shop Carbon

Your team enters the energy side directly: grid electricity for the arc furnace, ladle furnace and rolling mill, natural gas for reheating and ladle preheating, and diesel or LPG for cranes, forklifts and scrap handlers. Carbon from graphite electrodes, charge carbon and fluxes depends on your melt practice, so GHG Metric's specialists help set up those process items for your mill.

Track Melt Shop and Rolling Mill Use With Easy Data Collection

Name each meter or fuel the first time, such as "EAF electricity" in kWh, and GHG Metric brings back the name and unit next month so only the new figure is needed. The status grid marks each item completed, in progress, pending or overdue, and with every furnace kept separate you can compare its consumption and emissions across months.

Reduce Steel Mill Emissions by Seeing Which Furnace Leads

Six activities are ranked by tCO₂e with their share of the mill total and an arrow against the previous period. If arc furnace power leads, scrap preheating, foamy slag practice or better furnace sealing come first; if reheating gas is close behind, hot charging and burner upgrades may pay off. The arrows confirm whether each step moved the figure.

Use Cases

When Steel Mills Need Plant Emission Figures

Requests like these push minimills and rerolling plants to put their emissions on a firm footing.

Environmental manager

An EAF mill answers an automotive supplier

A car parts maker asks its steel supplier for Scope 1 and 2 emissions per ton of steel. The environmental manager enters a year of furnace power and reheating gas, works with GHG Metric's specialists on electrode and charge carbon, and shares the breakdown.

Owner

A rerolling mill owner learns what to track

A small mill that only reheats and rolls bought-in billets has no melt shop. The owner sets up reheating furnace gas, mill electricity and forklift fuel without specialist help and finds that reheating gas makes up most of the total.

Finance director

A finance director compares two sites before a capex decision

A group running a melt shop and a rerolling mill needs one total and a fair split. With each site as its own location, the finance director sees results per site and combined, and sets a reduction target for the melt shop first.

FAQ

Steel Production Carbon Emissions FAQ

Why should a steel mill track its carbon emissions?

Steel buyers in automotive, construction and machinery now ask suppliers for Scope 1 and 2 emissions, and many compare mills on those figures. Tracking also links CO2 to the two largest cost lines in most mills, arc furnace power and reheating gas. GHG Metric lets a mill handle the energy side itself and get specialist help with melt shop carbon.
