Özet

The steel industry, which has entered many value chains closely, affecting strategic sectors globally, is responsible for 7-9% of global greenhouse gas emissions. Therefore, the steel industry is among the key sectors in reducing carbon emissions. Providing inputs to many strategically important sectors, the iron and steel industry needs change and transformation in the context of combating climate change. Green steel production is a concept that has become increasingly common in recent times in this regard. The concept involves implementing technologies that generate minimal waste to the environment through technical, economic, and commercial evaluations for green steel production. This approach emphasizes the effective and efficient use of raw materials to preserve our natural resources, contributing to the concept of sustainability. This concept holds critical importance for the sector's long-term success and competitiveness. A sustainable iron and steel industry will not only benefit the environment but also provide significant advantages for the economy and society. This transformation will create new job opportunities, improve energy security and public health, and contribute to building a more livable world.

The journey towards sustainability in the iron and steel sector will not be easy. The transition to a sustainable iron and steel industry can only be achieved through the collective efforts of all stakeholders (such as producers, suppliers, customers, governments, and civil society organizations). Urgent steps are required to be taken for the necessary financial investments, technological innovations, and the development of public policies for this transformation. The steel industry is striving to develop new and sustainable methods to make steel production more environmentally friendly. One of these methods is hydrogen-based green steel technology, which can reduce carbon emissions by up to 95%. By using renewable energy sources such as wind and solar to produce hydrogen fuel and separating oxygen from iron ore, it is possible to achieve "zero" carbon emissions. Steel production using clean energy sources like hydrogen instead of coal or natural gas is referred to as green steel. Hydrogen-based steel production holds significant potential for reducing carbon emissions, making it a critical element in the fight against climate change. The industry is actively exploring and implementing these innovative approaches to pave the way for a more sustainable and environmentally friendly future.

The World Steel Association has set the goal of achieving net-zero emissions by the year 2050. Many companies are investing in low-carbon production technologies to meet this target. ArcelorMittal, the world's largest steel producer, is making various investments to increase energy efficiency and reduce emissions. The company has significantly reduced energy consumption by implementing waste heat recovery systems in its European facilities. Swedish steel company SSAB has set the target of reaching net-zero emissions by 2045. To achieve this goal, the company is investing in new technologies such as hydrogen-based iron production. As the seventh-largest steel producer globally, Turkey urgently needs to take measures to reduce carbon emissions in production to maintain competitiveness in steel exports to the EU. Otherwise, it may face additional taxes ranging from 8% to 19% under the carbon border adjustment mechanism, depending on the existing conditions. In conclusion, the concerted efforts of all stakeholders in the industry are crucial for significant steps towards sustainable green steel production, making it a necessity from environmental, economic, and social perspectives.
