The Meteorological Service Singapore (MSS) provides weather information to support public health and socio-economic activities.

NEA adopts a multi-pronged approach – which includes surveillance and enforcement, community outreach and education, and research, to tackle vector-borne diseases such as dengue fever.

During these visits, the officers will highlight all potential mosquito breeding grounds in that particular home and the corrective measures the resident needs to undertake.

This approach has yielded good results, with Singapore successfully avoiding a serious dengue outbreak, as experienced in 2005 when 14,209 people were infected with the fever.

NEA maintain an effective system of public cleansing to keep Singapore clean and prevent environment-related diseases.

The NEA works closely with their "3P Partners" (the people, public and private sectors) to promote anti-littering practices and to encourage members of the community to take ownership of their litter and keep their surroundings clean.

Regular checks on food establishments, swimming pools and public toilets are carried out to ensure that a high standard of hygiene is maintained.

On 11 September 2009, NEA signed a landmark Voluntary Agreement with 16 major retailers and suppliers, to provide more energy efficient appliances and encourage more Singapore households to purchase them.
