ESG (Environmental, Social, and Governance) criteria assess companies based on their environmental, social, and governance practices. Environmental factors relate to a company's impact on the environment, such as greenhouse gas emissions, resource usage, and waste management. Social factors focus on a company's relationships with employees, customers, and communities, including labor conditions, equality, and diversity support. Governance factors concern the way a company is managed, including ethics, transparency, risk management, and leadership. Investors and companies increasingly consider ESG criteria when making investment decisions, as these factors can impact a company's long-term sustainability and performance.
