In the context of a circular and climate-neutral economy, organizations face growing pressure to embed sustainability within their core business models. This chapter explores the strategic role of Green Human Resource Management (GHRM) in cultivating a strong employer brand, positioning it as a critical intangible asset through the lens of the Resource-Based View (RBV). Drawing on RBV theory, we argue that green employer branding not only strengthens organizational reputation but also attracts and retains environmentally conscious talent, ultimately supporting long-term sustainable competitive advantage. The chapter introduces a conceptual model linking GHRM practices to employer branding outcomes, supported by empirical insights and examples from sustainability-leading organizations. By highlighting the synergies between HRM, sustainability, and strategic branding, we offer practical pathways for business leaders and policymakers to align human capital strategies with the imperatives of a climate-neutral and circular economy.
