As the steel industry faces growing pressure to decarbonize, climate disclosure frameworks such as the CDP Climate Change Rating, and ResponsibleSteel™, to mention some, are playing a bigger role in how companies are assessed. A strong CDP score reflects meaningful progress in managing climate-related risks, cutting emissions, and improving transparency — all of which are increasingly important to investors, regulators, and the public alike. While strategy and reporting are essential, operational technology plays a crucial role in unlocking the actual emissions reductions that drive better scores. One emerging solution is Luxmet’s ArcSpec system for EAFs, which leverages real-time optical emission spectroscopy to improve process control and efficiency.
Operational technology plays a crucial role in unlocking the actual emissions reductions that drive better scores.
How ArcSpec contributes to climate goals
ArcSpec offers measurable improvements across several operational metrics that tie directly into CDP scoring categories, particularly around Scope 1 and Scope 2 emissions, resource efficiency, and energy use.
Reduce indirect CO₂ emissions
By typically improving energy efficiency by 3–6%, ArcSpec directly lowers electricity consumption, a major contributor to Scope 2 emissions. This results in immediate, quantifiable emissions reductions without requiring changes to external energy sources.
Boost process efficiency
With up to 7% faster tap-to-tap times and more precise timing of scrap charging, facilities can reduce overall furnace power-on time. Less time with the power on means lower energy use per heat.
Cut consumable waste
ArcSpec enables smarter control of electrode power, typically resulting in 5–10% less electrode consumption and reduced refractory wear. This not only saves costs but also supports better resource management — an increasingly important focus area in climate disclosures.
A strategic tool for climate ratings and beyond
The climate disclosure frameworks reward not just long-term pledges, but the implementation of concrete, emissions-reducing actions. Technologies like ArcSpec represent a practical step manufacturers can take today to align operations with science-based targets and demonstrate credible progress.
As investors, customers, and regulators continue to raise expectations, the ability to point to smart, measurable technology adoption can help set leaders apart.
