ESG stands for Environmental, Social, and Governance, and it has revolutionized the way investors think about portfolio construction. Traditionally, investors would focus solely on financial returns, often ignoring the impact their investments had on the world around them. However, in recent years, there has been a shift towards a more sustainable and responsible approach to investing.\n\nESG investing considers the environmental impact of companies and industries, such as greenhouse gas emissions, water usage, and waste management. It also looks at the social impact, including employee relations, diversity and inclusion, and community engagement. Lastly, it focuses on governance issues, such as board independence, executive compensation, and shareholder rights.\n\nThe rise of ESG investing can be attributed to a number of factors.

This correlation between ESG performance and financial performance has caught the attention of investors, who are now seeking to capitalize on these potential benefits.\n\nFinally, regulatory frameworks and reporting standards have also played a role in the rise of ESG investing.
