Environmental management became a crucial part of societal life and a dominant issue for every sector of economies in the developed world. However, the previous relative absence of advanced EMS in the Libyan petroleum industry made the companies not able to compete in the international petroleum sector. Since decades ago, the Oil and Gas industry in Libya has been trying to transform by aligning itself according to the requirements and expectations of the industrial nations of the world. This work aims to know the Application prospects of the environmental management standard ISO 14001: 2015 in the oil and gas industry sector in Libya and the extent of its impact in raising the level of environmental awareness among employers, interested parties, and employees.
