The steel industry accounts for approximately 7–9% of global carbon dioxide emissions, making it one of the largest industrial contributors to climate change. As the world moves towards carbon neutrality, green steel is emerging as a revolutionary approach to reduce the environmental footprint of steel production.

Green steel refers to steel produced using processes that significantly cut or eliminate carbon emissions. This shift is driven by technologies such as hydrogen-based direct reduced iron (H₂-DRI), electric arc furnaces powered by renewable energy, and carbon capture, utilization, and storage (CCUS).

Hydrogen-based steel production replaces traditional carbon-intensive coke with hydrogen gas to remove oxygen from iron ore, releasing only water vapor instead of carbon dioxide. Pilot projects like Sweden’s HYBRIT initiative have successfully demonstrated fossil-free steelmaking at a commercial scale.

Electric arc furnaces, which recycle scrap steel, are increasingly powered by renewable electricity, further reducing emissions. Additionally, carbon capture technologies are being integrated into ...
... existing steel plants to trap and repurpose CO₂ emissions before they reach the atmosphere.

Governments worldwide are supporting this transformation through incentives and stricter environmental regulations. Major steel manufacturers and buyers in industries such as automotive and construction are demanding low-carbon steel to meet sustainability goals.

While challenges such as scaling hydrogen production and achieving economic competitiveness remain, the global push for sustainable steel production continues to accelerate. Green steel technologies represent a critical pathway for decarbonizing one of the world’s most essential industrial sectors.
