What is ESG Investing?
ESG investing evaluates companies based on environmental impact (carbon emissions, resource usage), social responsibility (labor practices, community relations), and governance quality (board independence, executive compensation). Global ESG assets under management surpassed $30 trillion by 2025, representing roughly one-third of total professionally managed assets worldwide.
ESG Integration in Practice
ESG strategies range from negative screening (excluding tobacco, weapons, fossil fuels) to positive selection (overweighting companies with strong ESG scores). Rating agencies like MSCI and Sustainalytics assign ESG scores on scales of 0-100 or AAA to CCC. Research from multiple studies suggests that companies with strong ESG profiles tend to exhibit lower volatility and comparable or slightly higher long-term returns than peers.
Key Considerations
ESG ratings lack standardization across providers, and the same company can receive vastly different scores depending on the methodology. Greenwashing, where companies overstate their sustainability credentials, remains a persistent challenge. Investors should examine the specific criteria and weighting used by any ESG fund rather than relying solely on the label.
