According to an article published by Harvard Business School (HBS), this concept refers to practising business “…without negatively impacting the environment, community, or society as a whole”1. To achieve this, companies have to identify how and whom they are affecting in every step of their business processes to make decisions and measure their impact. Nowadays, sustainability is not only a matter of ethics or responsibility, it is also a concept used by investors to assess business through metrics like ESG (environmental, social, and governance). According to the HBS, companies with high ESG ratings tend to have more financial returns and a lower cost of debt and equity. This means that companies can benefit from practising business sustainability after COVID-19.
