Sustainability performance is measured through key performance indicators (KPIs) such as carbon emissions, water usage, waste management, and energy efficiency. Social factors, including employee well-being and diversity, are also considered. Governance-related metrics like board diversity and ethical business practices play a crucial role in sustainability assessment. Investors and businesses rely on standardized frameworks to evaluate these metrics. Companies that focus on improving these KPIs can enhance their ESG ratings and attract impact-driven investors.
