ESG in finance can refer to, among other things, financing tools such as Green, Social, and Sustainability Bonds and similar ESG-related debt instruments, as well as the separate discipline of ESG Investing. ESG stands for Environmental, Social, and Governance. Investors are increasingly applying these non-financial factors as part of their analysis to identify ESG-related risks and opportunities in particular investments. ESG metrics have not historically been included in financial reporting, though companies are increasingly making disclosures in their annual report or in a standalone sustainability report, and regulatory requirements for such disclosures, including from the SEC, are expanding.

Greenwashing is the act of making false, misleading, or exaggerated claims about an entity’s environmental or sustainability record or practices, including the environmental impact of operations, products, or services. Greenwashing reflects a gap between the symbolic and substantive action taken by a company or product in order to gain an environmentally friendly image. For example, greenwashing occurs when a company spends time and money advertising goods or services as environmentally friendly, closer to nature, or otherwise “green,” when the impact on the environment is not materially distinct from other comparable goods or services.
