The term, ESG, which stands for environmental, social, and corporate governance, first appeared in a report in the United Nations Global Compact signed in 2004. It is an analytical framework that serves as a guideline for stakeholders to comprehend the ways in which corporate organizations handle risks and opportunities concerning "environmental, social and corporate governance." It is considered as a criterion that market investors should abide by in order to assess whether enterprises or company operations have been on the right track. Listing the essential tasks needed to be implemented in order to fulfill the goals of sustainability, ESG is the principle of practicing CSR (Corporate Social Responsibility). As initiated in 1999 by the United Nations, CSR denotes the concept of sustainability in a more encompassing manner. Moving into 2015, the United Nations made more concrete and detailed measures by proposing and setting the 17 goals of sustainable development(SDGs) that should be achieved by the year 2030. The first aspect of ESG entails environmental protection which informs companies of heeding to the environmental sustainability issues to decrease damage to the environment. The companies should be responsible for tackling matters related to climate change as well as other environmental and ecological issues. Such kinds of things could include reducing carbon emission, dealing with sewage management, and instigating environmental pollution prevention and control, etc. The second respect of ESG contains social responsibility that requires companies to accomplish their social responsibilities by putting on their social performances. These comprise paying special attention to employees' wages and benefits, the working environment, and schemes to give back to society and communities. As for the last part of ESG, corporate governance, it is referred to the operational performance of a company to sustain the company's own reputation and development, including business ethics, shareholder rights, information transparency, and risk management, etc. Nowadays not only the concept of sustainability but also its governing principles and practices have become prevalent among governmental and cooperate organizations. Its significance is without dispute and requires dedications from governments and societies alike.
