What is ESG? Environmental, Social, and Governance are a set of criteria used by responsible investors and customers to assess a company’s overall health and resiliency. Environmental criteria communicate a company’s impact on the environment and how it plans to address pressing issues such as climate risk, waste management, and energy transition. Social criteria examine a company’s relationship with its employees, clients, and the communities in which it operates. Governance criteria deal with a company’s leadership and how it operates.
Stakeholders are increasingly demanding compelling and actionable ESG strategies. Disclosing and improving performance on ESG metrics is correlated to financial performance and long-term value creation.
