National Environment Agency

The Environmental Public Health Division conducts comprehensive ground surveillance and takes preventive measures to ensure a high standard of public health and hygiene. It is responsible for the overall cleanliness in Singapore and imposes a high standard of hygiene requirements on the food retail industry. It also implements the Hawker Centres Upgrading Programme (HUP) and the Clean Public Toilets Programme. It enforces smoking ban in places such as hawker centres, food shops, shopping centres, factories and offices; and conducts vector control against mosquitoes and rats.

The Environmental Protection Division is responsible for implementing programmes to monitor, reduce and prevent environmental pollution. It is also responsible for providing refuse disposal services through four waste-to-energy incineration plants and an off-shore sanitary landfill. To conserve energy resources and landfill space, the division implements programmes to minimise waste generation, and maximise recycling and energy conservation.

The Meteorological Service Singapore (MSS) provides weather information to support public health and socio-economic activities. It also issues haze alerts and provides vital meteorological services to the aviation and maritime communities and the military. MSS is also on tsunami watch as part of a regional network set up after several coastal areas in Asia were devastated by the 2004 Indian Ocean earthquake and tsunami.

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. Most recently, it rolled out educational home visits, where NEA officers visit homes in areas where there are less than 10 dengue cases, to educate residents on how to prevent mosquitoes from breeding in their homes. 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. No enforcement action will be taken against the resident for any mosquito breeding found on such visits.

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. From 2007 to 2011, the number of dengue cases were 8,826; 7,031; 4,497; 5,363; and 5,330 respectively.

NEA plays an important role in overseeing the cleansing of public areas in Singapore. NEA takes a three-pronged approach to keeping our environment clean, which includes: Public Cleansing; Public Education and Enforcement. NEA maintain an effective system of public cleansing to keep Singapore clean and prevent environment-related diseases. The cleansing of public roads and pavements is largely carried out by contractors engaged by the NEA.

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.

In April 2006, Singapore announced accession to the Kyoto Protocol. As a non-Annex I country, Singapore does not have targets set under KP, but it is eligible to participate in carbon credit exchanges arising from approved Clean Development Mechanism projects conducted in the country. The National Environment Agency is the designated authority coordinating CDMs. It is also spearheading ongoing measures to encourage energy efficiency and lower carbon emissions.

In April 2008, NEA launched the 10% Energy Challenge to get households to cut their electricity consumption by at least 10%. As part of this campaign, NEA collaborated with grassroots organizations and charities to train volunteers to conduct energy audits and identify wasteful energy consumption habits.

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.

Under the Voluntary Agreement, participating retailers and suppliers will voluntarily commit to achieving targets set out by the NEA, including retiring stock of energy inefficient models and introducing more 3- and 4-tick models, so that energy efficient models form at least 50% of their model range after six months, and 60% of their model range after one year. Signatories also voluntarily commit to promote energy efficient appliances, as well as improve the availability and affordability of energy efficient appliances available in their stores.

Since independence, Singapore's growing population and economy have resulted in a large increase in solid waste. In 1970, about 1,300 tonnes per day of solid waste were disposed of. This increased to 7,000 tonnes per day by 2006, a six-fold increase from 1970.

To address the solid waste problem, Singapore has put in place an integrated solid waste management system that ensures that all waste that are not recycled, are collected and disposed of safely at waste-to-energy incineration plants or at the offshore sanitary landfill (Semakau Landfill) in the case of non-incinerable waste.

As a result, overall recycling rate has increased from 40% in 2000 to 56% in 2008. Waste growth has also been curtailed. The total waste (domestic and non-domestic) disposed of in 2008 was 7,179 tonnes per day, a 6% reduction as compared to 2000. As a result, the lifespan of Semakau Landfill has increased from 25–30 years to 35–40 years.
