What is ESG?

Environmental, social, and governance (ESG) is a lens that can be applied to any form of investing to consider non-financial factors that are not traditionally reported to assess an investment’s overall worthiness.

In recent years, firms increasingly add ESG metrics to their investment processes to provide for more complete analyses and support better investment decision-making. Discussion of ESG activities is also being added to annual reports and, in some cases, being built into standalone ESG reports.

Environmental (E)

Covers themes that impact the Earth, both positively and negatively. Includes climate change, natural resources scarcity, pollution and waste, permitting, and environmental opportunities.

Social (S)

Consists of people-related elements both within the firm and society as a whole. Includes labor issues, human rights, customer satisfaction, data protection and privacy, and diversity and inclusion.

Governance (G)

Encompasses items relating to the firm’s leadership and board as well as the firm's implementation of ESG policies. Includes board composition, diversity of the board, ethical business practices, lobbying, political contributions, account and tax transparency, and relationships with the SEC and other regulatory bodies.
