This report discusses the benefits of implementing a formal externally audited Environmental Management System (EMS) for organisations. It explores how an EMS can help manage regulatory compliances, utilise resources effectively, promote brand image, increase financing opportunities, raise sales and revenues, enhance credibility, and encourage workforce. The report also analyzes the external (PESTLE) factors that can impact the company's operations and identifies risks and opportunities that can be best managed with the implementation of an EMS. It further discusses how the organisation can integrate its legal and other requirements in the implementation of the EMS. The social, political, and economic trends affecting the company and/or its sector are also examined and their incorporation into the EMS is discussed.
