This data point covers direct greenhouse gas (GHG) emissions from Corgon 18%, a shielding gas mixture commonly used in welding (typically 82% argon + 18% CO₂). The CO₂ portion contributes directly to Scope 1 emissions, while argon is inert but still tracked for completeness.
You should report the total volume of Corgon 18% consumed, converted into tonnes (t), during the reporting year.
What to include:
All Corgon 18% shielding gas consumed during welding operations.
Both production and maintenance-related welding activities.
Report in tonnes (t).
What not to include:
Other shielding gas mixtures (report separately if relevant).
Stored but unused gas.
CO₂ emissions from combustion processes (covered elsewhere).
Estimation Methodology:
Preferred: Use supplier invoices or delivery logs.
If unavailable, estimate using:
Cylinder capacity × number of cylinders consumed.
Welding machine operation hours × typical gas consumption rate.
Convert all volumes to tonnes (t) before reporting.
