Sustainable investing emphasizes financial investments in businesses or projects that yield long-term positive impacts on environmental, social, and governance (ESG) aspects, aligning financial goals with ethical principles. The triple bottom line—people, planet, and profit—serves as a crucial framework for assessing investments, while integrating ESG criteria enables better risk management and can enhance financial performance. Despite challenges like inconsistent ESG reporting standards, the future of sustainable investing appears promising, with growing investor interest and supportive policies aimed at fostering responsible investment practices.
