Explanation:

Recently, the Indian Navy took steps to reduce its environmental footprint through energy conservation, minimising marine pollution and use of alternative sources of energy. The Indian Navy Environment Conservation Roadmap’ (INECR) has been the guiding document and key enabler for progressively achieving this vision of the Indian Navy to add a Green Footprint to its Blue Water operations.

• In efforts to reduce carbon footprint, measures have been brought in force for a steady increase in utilisation of e-vehicles such as e-cycles, e-trolley and e-scooters. 
• To promote the same, units observe ‘No Vehicle Days’ regularly and the concept of a ‘Vehicle Free Base’ is also being introduced in some Naval establishments.
• Indian Navy has voluntarily implemented all six schedules of the International Convention for the Prevention of Pollution from Ships (MARPOL) regulations. Hence both statements are correct.
