All the proposed metro rail stations being built under Corridor I (Danapur to Khemnichak) and Corridor II (Patna Junction to Patliputra Bus Terminal) will be green buildings with provisions to conserve energy and rainwater and enable a sustainable environment. Delhi Metro Rail Corporation (DMRC), the nodal agency for the Patna metro rail project, is taking measures to curb air pollution during the construction works across the city and design the stations as eco-friendly structures by following green norms in order to utilise natural resources and local products more effectively.
