Turkey's steel industry is accelerating its green transformation in response to the European Union's Carbon Border Adjustment Mechanism and rising global demand for low-carbon steel. The sector produces over thirty-five million metric tons annually, with seventy percent coming from electric arc furnaces, giving it a natural carbon advantage. Producers are now investing in renewable energy, scrap optimization, and hydrogen readiness. Analysts estimate the sector needs between three and five billion dollars in green investment over the next decade to stay competitive.
