Historically, sustainability in real estate has centered on green buildings and environmentally friendly structures. However, these efforts have often been confined to individual buildings, overlooking the broader ecosystem. This research paper expands the focus, investigating how various stakeholders in the real estate sector, including developers, financiers, suppliers, and advisors, are addressing environmental challenges. Utilizing the Global Reporting Initiative (GRI) as a framework, the paper analyzes publicly available company disclosures. The results highlight a strong emphasis on emission and energy-related indicators, while other vital aspects such as biodiversity, supplier assessment, and materials are often neglected. The paper also explores regional variations and alignment with global standards, providing insights into the current state of sustainability reporting within the industry. By identifying areas for improvement and underscoring the importance of a multi-stakeholder approach, this study contributes valuable perspectives to the ongoing dialogue on environmental stewardship in real estate and offers actionable recommendations for enhancing transparency and sustainability practices.
