We refer to Mr How Ti-Hwei's letter ("Ingrain sustainability culture during national service") on 21 January and thank him for his suggestions.

The Singapore Armed Forces (SAF) has incorporated environmental sustainability as a key consideration within the organisation while ensuring that its core mission and operational readiness to defend Singapore are not compromised. Recycling measures such as food waste segregation and recycling at cookhouses as well as recycling bin provision have been adopted in some SAF camps, and these efforts will be progressively widened to more locations. Collection points have also been set up at other premises including SAFRA clubhouses for national servicemen to recycle their old uniforms, boots and other equipment. To improve energy efficiency, the SAF has embarked on initiatives such as the development of energy-efficient buildings, installation of solar panels on buildings and replacement of administrative vehicles with hybrid models.

The Ministry of Defence and the SAF will continue to encourage and support sustainability behaviour among our national servicemen and contribute to a sustainable future for Singapore.
