Düşük karbonlu ekonomilere geçiş, yenilenebilir enerji teknolojileri, elektrikli araçlar ve enerji depolama sistemlerinde hayati öneme sahip kritik metallere olan talebi artırmıştır. Bu metaller, küresel karbon nötrlüğü hedeflerine ulaşmak için gerekli yeşil teknolojilerin etkinleştirilmesinde temel bir rol oynamaktadır. Ancak, bu metallerin çıkarılması, işlenmesi ve tedarik zincirleri çevresel, ekonomik ve jeopolitik zorluklar ortaya çıkarmaktadır. Bu çalışma, çevresel etki, ekonomik uygulanabilirlik, kaynak mevcudiyeti ve teknik performans gibi birden fazla kriteri dikkate alarak kritik metalleri sistematik bir şekilde değerlendirmek ve önceliklendirmek için Analitik Hiyerarşi Süreci (AHP) yöntemini kullanmaktadır. Uzman görüşlerini ve güvenilir verileri içeren AHP çerçevesi, sürdürülebilir kaynak yönetimi bağlamında kapsamlı ve yapılandırılmış bir karar alma yaklaşımı sunmaktadır. Bulgular, lityumun hem çevresel hem de teknik açıdan avantajlı özellikleri nedeniyle en kritik metal olduğunu, etik kaygılara rağmen stratejik önemi dolayısıyla kobaltın ikinci sırada yer aldığını, ardından enerji yoğunluğu nedeniyle nikelin ve kalıcı mıknatıs uygulamaları açısından neodimyumun geldiğini ortaya koymaktadır. Bu analiz, politika yapıcılara, sanayiye ve paydaşlara sürdürülebilir kalkınma hedefleriyle uyumlu kararlar almalarında rehberlik etmeyi ve düşük karbonlu bir geleceğe geçişi desteklemeyi amaçlamaktadır.

CRITICAL METAL SELECTION FOR LOW CARBON EMISSION USING THE ANALYTIC HIERARCHY PROCESS

Öz

The transition to low-carbon economies has heightened the demand for critical metals essential in renewable energy technologies, electric vehicles, and energy storage systems. These metals play a fundamental role in enabling the green technologies required to meet global carbon neutrality targets. However, their extraction, processing, and supply chains introduce environmental, economic, and geopolitical challenges. This study employs the Analytical Hierarchy Process (AHP) to systematically evaluate and prioritize critical metals by considering multiple criteria, including environmental impact, economic viability, resource availability, and technical performance. By integrating expert insights and robust data, the AHP framework provides a comprehensive and structured approach to decision-making in sustainable resource management. The results underscore lithium’s critical role, driven by its favourable environmental and technical properties, followed by cobalt for its strategic relevance despite ethical concerns, nickel for its high energy density, and neodymium for its role in permanent magnet applications. These findings aim to inform policymakers, industry leaders, and stakeholders in making well-grounded decisions that align with sustainable development objectives and facilitate the transition to a low-carbon future.
