Audit-Ready Carbon Reporting for Semiconductor Manufacturers
Track fab facility energy, process gas emissions, cleanroom systems, and chip lifecycle carbon for semiconductor operations.
The Industry Hotspot: Fab Energy and Process Gas Emissions
Fab energy and process gases dominateSemiconductor manufacturing emissions concentrate in fab electricity consumption and process gases. Cleanroom HVAC systems operate continuously maintaining temperature, humidity, and air quality. Lithography, deposition, and etching equipment consume substantial electricity. Process gases including fluorinated compounds have very high global warming potential. Small mass emissions create large CO2-equivalent impact. Abatement systems capture and destroy process gases reducing emissions. NetNada tracks fab facility energy per wafer, monitors process gas consumption and abatement, calculates cleanroom HVAC overhead, and reports product carbon intensity.
SASB Industry Definition
The Semiconductors industry designs and manufactures integrated circuits, memory chips, processors, and fabrication equipment. Semiconductor fabs are energy-intensive facilities requiring cleanroom environments, high-purity chemicals, and precise process control. Emissions include electricity for fab equipment, process gases with high global warming potential, and facility HVAC. Product use-phase efficiency gains often offset manufacturing footprint.
