Definition of ESG Investing

Environmental, Social, and Governance (ESG) investing refers to the practice of considering these three factors when making investment decisions. ESG investing aims to create a more sustainable and responsible financial system by incorporating non-financial factors into investment processes.

ESG investing has gained significant attention in recent years as investors recognize the potential risks and opportunities associated with environmental, social, and governance factors. ESG investing allows investors to align their investments with their values and contribute to a more sustainable future.

The growth of ESG investing is attributed to increased awareness of sustainability issues, evolving regulatory frameworks, and a shift in investor preferences. In response, companies have improved their ESG practices, and the number of ESG investment products has expanded rapidly.
