Argon: Emissions

How you split the power bill changes its footprint

What this tab covers The greenhouse-gas footprint per tonne, split by lifecycle phase (feedstock, production, movement, use, end of life), the global total, other environmental impacts, levers and low-carbon routes, India's position, and where the investment opportunity lies. Emission intensity 0.25 t CO2e per t range about 0.05-0.5 · allocated ASU power of about 0.3-0.6 MWh per t at a 0.45-0.5 kg CO2 per kWh grid; allocation method changes the result

Per t of liquid argon, cradle-to-gate. Intensity: indicative (basis: energy use x grid intensity). Global total: not published.

Feedstock	zero (air)	0%	none	air is free	not applicable
Production / process	about 0.2 t CO2e per t	85%	allocated ASU electricity	allocation by mass or value moves the figure	indicative

Use	not applicable	–	inert, returns to air	argon is not a greenhouse gas	not applicable
End of life	not applicable	–	vented	argon is seldom recycled in large-volume uses (USGS); some fabs and crystal pullers recycle it	USGS MCS 2026

Other environmental impacts

None material beyond power use.

Levers to cut emissions

Renewable power for ASUs
Argon recovery and recycling in crystal pullers and fabs
Higher argon recovery in new ASUs

India

No India-specific data; footprint follows the coal-heavy grid.

Emission figures are indicative global averages from the life-cycle studies named; actual footprints vary widely by site, energy mix and method.

Low-carbon routes

ASU argon on renewable power	near zero	little or none	gas majors' renewable PPAs (indicative)	indicative

For a climate investor Argon is a small emitter. The angle is supply security for solar ingot and wafer plants that India is building under its PLI scheme, which need reliable UHP argon, and argon recycling systems for crystal pullers. Indian argon prices above Chinese export levels suggest room for new argon-capable ASUs near solar and steel clusters.
