Sustainability reporting is the practice of measuring, disclosing and being accountable for an organization's economic, environmental and social impacts. It allows companies to benchmark performance, demonstrate transparency and compare themselves to others. The Global Reporting Initiative developed a sustainability reporting framework to standardize reporting and provide guidance on strategy, management approach and performance indicators. Effective sustainability reporting can help companies access new markets, attract investment and improve relationships with stakeholders. However, barriers include unclear standards, resource constraints and lack of management support.
