Introduction
The financial world is undergoing a profound shift. No longer is success measured solely by quarterly earnings or stock performance. Today, investors are increasingly evaluating businesses through the lens of environmental, social, and governance (ESG) criteria. This movement—often called ESG investing or sustainable finance—reflects the growing awareness that profitability and responsibility must go hand in hand.
As climate change intensifies, social justice movements gain momentum, and corporate accountability becomes non-negotiable, sustainable finance has emerged as a powerful tool to align capital with long-term global well-being. Let’s explore how ESG investing is transforming markets, the rise of green bonds and impact investing, and what the future of finance looks like when profits meet purpose.
What is ESG Investing?
- Definition

- Companies with strong ESG practices are more resilient to risks.
- Studies suggest ESG-focused portfolios often outperform traditional ones in the long run.
