The document aims to integrate existing environmental laws, and policies through a meta-synthesis approach. Priority is given to identifying driving forces, pressures, states, impacts, and responses concerning the company's environmental responsibilities, using expert panels and the DPSIR framework. Based on the outputs of these methods, input data for the PolicyMaker software were utilized to formulate comprehensive environmental strategies, policies, and impacts relevant to the Railway company as a key policymaking actor. The foundational values, vision, goals, methods, and national actions, have been defined and organized to ensure the company can leverage the environmental policy document as an opportunity to promote the welfare, comfort, and tranquility of current and future generations within its operational scope and ultimately contributing to sustainable development. The analysis of the research results highlights key features, including value orientation, ethical emphasis, holistic perspectives, community focus, institutional integrity, knowledge-based approaches, and forward-thinking in managing, supervising, and strategically monitoring scientific, research, operational, and technological activities related to environmental sustainability in the railways. The findings indicate that the policymaking needs in the company are at a primary and foundational level, largely due to the absence of independent environmental institution building by experts.
