The North West CDC (NWCDC) and National Environment Agency (NEA) jointly launched the district-wide, 10-year Eco Plan, in support of the National Sustainable Development Blueprint.

Known as Green Living at North West, the plan aims to strengthen efforts to galvanise and empower the community to take on greater environmental ownership.

The Green Living at North West Eco Plan was launched by Dr Teo Ho Pin, Mayor of North West District, Mr Andrew Tan, former Chief Executive Officer of NEA together with Minister Lim Swee Say, Minister K Shanmugam and four other Advisers of North West District.

Green Living @ North West encompasses five pillars namely CLEAN Everyday, LEADengue, Fight Against Climate Change, 3Rs (Reduce, Reuse and Recycle) and CLEAN Toilets. Each pillar will have specific programmes to help residents in the North West District to take ownership of the environment.

Programmes in “Green Living @ North West”

  • CLEAN Everyday is to keep the North West District clean and hygienic. Such programmes include Anti-littering and social graciousness projects. Two projects from this pillar include the Waterways Clean-Up @ North West and HABIT Skit.
  • LEADengue is to ensure that the North West District is kept dengue-free. Each year, a specific theme will be developed to address the dengue situation. Do the Mozzie Wipeout and Mozzie-Free Homes @ North West are two projects from this pillar.
  • Fight Against Climate Change is to focus mainly on educating residents to conserve natural resources such as water and electricity. The measureable outcome for the resident is the cost-savings from their utility bills. In the long-run, it helps Singapore saves on resources. Other key events in this pillar include international events such as Earth Hour and Reduce @ North West are two projects from this pillar.
  • The 3Rs (Reduce, Reuse and Recycle) is to reduce Singapore’s landfill needs and to educate residents on what can be recycled and what cannot. Recycle @ North West is a core project from this pillar.
  • CLEAN Toilets is the final pillar that focuses on keeping public toilets clean. Such programmes include STAR @ North West.

North West CDC believes it only takes a small effort from each individual to adopt a green living lifestyle that would contribute to the district’s 10-year eco-plan. Residents are encouraged to start picking up good habits towards Green Living as it is important for us to take ownership of enhancing our environment now and for future generations to come.

Our Focus on a Green Living Culture

The North West District aims to create environmental awareness for all our residents. Our core programmes include the Recycle @ North West, in which we work closely with our 3P partners to implement ‘active’ recycling through sorting and segregation, so that 100% of the recyclables collected are recyclable. Active recycling breaks away from the current recycling practices. Focusing on environmental sustainability, this form of recycling requires active commitment in regular recycling, acquisition of green knowledge and sharing of information to the community.

North West CDC aims to support this initiative by working with partners and grassroots volunteers to set up recycling points. Each supported by a community green club, these recycling points serve as platforms for residents to better understand the importance of resource conservation through experiential learning and sharing with volunteers. For instance, when residents gather to sort the collected items, they learn in the process the types of items which are recyclable. They can then share this information with their families, friends and neighbours.

In the long run, residents can become active volunteers or even trainers to help promote the message of resource conservation to others in the community. North West CDC recognises the importance of individual and community effort in making a difference to the environment and with this in mind, North West CDC is targeting to form the largest district-level network of community green clubs and residents will better understand and commit to the concepts of reduce, reuse and recycle, leading to resource conservation in the long run.

Currently, North West CDC has 11 community green clubs contributing 150,000 kg of pure recyclable items for the past two years. In total the North West CDC has 400 recycling volunteers and outreach and education has expanded to 5,000 households on resource conservation. Proceeds from the sale of the sorted and non-contaminated recyclables will go towards helping needy students towards their school-based needs.

Another focus programme is the Reduce @ North West, in which the CDC intends to educate residents about the importance of energy conservation in order to battle climate change and to save money and resources for the household. The programme sees student volunteers engaging households in the North West District on climate change and energy conservation issues. Households are encouraged to participate in the energy audit, where their electricity bills are tracked over a four-month period.

Reduce @ North West has reached out to 88,000 households, with 7,300 student volunteers committed to the cause over the past two years. Total energy saved for this programme is 103,000 kWh.

A recent focus programme for the District includes the Green Homes @ North West initiative. The three-year initiative will see agency representatives, grassroots and student volunteers reaching out to new Build-to-Order (BTO) home owners in the North West District to promote energy conservation, water conservation and recycling. New and existing home owners will be able to access an online resource guide containing tips on the use and selection of energy efficient electrical appliances and green habits they can adopt as part of their lifestyle. Using the knowledge gained, home owners minimise their total household energy usage, reduce their electricity bills and contribute to a greener environment.

To qualify as a ‘Green Home’, homes need to meet the five criteria listed below. The first four criteria were chosen based on the prevalent use of appliances in an average household with the highest energy consumption. The fifth criterion aims to encourage residents to practise the 3Rs (Reduce, Reuse, Recycle) at home.

  1. An air-conditioner with a four-tick energy efficiency rating,
  2. A refrigerator with a four-tick energy efficiency rating,
  3. An instantaneous water heater,
  4. A washing machine with a three-tick water efficiency rating and
  5. A recyclables collection area in their home.

Home owners will have their homes certified as a ‘Green Home’ upon passing an audit of the five criteria. The North West CDC and NEA aim to reach out to some 12,000 new home units within three years.

Green for Good Causes

Eco Quest @ North West is an online e-learning portal to encourage environmental education for students and residents in North West District. The CDC wanted to use new media to drive a good cause to raise funds towards the North West Student Support Fund (NWSSF) for the needy students in the North West District. For every successful completion of each e-learning module by a participant, a corporate company will make a donation of $3 towards the NWSSF. The North West Student Support Fund is a fully sponsored fund by members of the public, community and corporate organisations set up by the North West CDC to provide educational-related assistance and support to needy students.

11,000 students from 60 schools raised $150,000 for needy students and the common purpose of advocating greater environmental ownership and active participation in the community.

Our Outreach

The CDC’s programmes intends to outreach to all residents in the District through a myriad of programmes which includes anti-littering, social graciousness, Dengue-prevention, recycling, energy and water conservation and clean toilets. North West District continues to place a strong emphasis on Green Living and its values.

Since the launch of the Green Living @ North West 10-year Eco Plan in 2009, the North West District has rolled out over 110 programmes to reach out to more than 700,000 residents under the five pillars of the Eco Plan over the past two years.

Our Partnership

North West District is keen to work with different partners, to create 3P partnerships.

The District relies on its strong and dedicated network of grassroots organisations, partner agencies, community green clubs, schools, green champions and volunteers to inculcate these green values in its residents. With further support from Grassroots Organisations, Town Councils and respective NGOs and Corporate Organisations, the North West CDC works with about 40 partners annually for the past two years in its Green Living programmes.

Chiang Rai – Thailand

Chiang Rai city is located at the northernmost of Thailand which is the gateway to the Mekong sub-region. The area of the city is 60.85 square kilometers. Registered population is 70,201 and non-registered is 80,000 – 100,000.

Chiang Rai’s clean and green land programmes are operated in accordance with the national policy which emphasizes on integrated management and waste minimization by 3R. For green areas, the existing ratio of green area is 5.65 square meters per capita which is according to the national criteria.

Solid Waste Management:

Solid waste management of Chiang Rai city consists of upstream, middle-stream, and downstream parts. In the upstream part, waste separation is emphasised. A cooperative network was created among private waste collectors, city’s waste collectors and private recyclers. Recycling banks such as community and school solid waste recycling banks are citywide. The philosophy of “3Rs” reduce, reuse and recycle, is widely taught and several activities were organized in transforming solid waste to useful materials such as souvenirs made of plant parts , plant pots from dry leaves etc. The city helps setting up a marketplace for selling such products in walking streets. On the middle-stream part, the city has full coverage of solid waste collection through a carefully organized fleet of collection trucks. Volunteers monitor and report any uncollected solid waste. Downstream, a five-pit sanitary landfill is used. Waste is dumped, compressed and covered with soil. Three wastewater treatment ponds are operated for controlling leachates. The first pond is an anaerobic treatment, the second and third ponds are aerobic treatment with 6 aerators. There are 7 groundwater monitoring wells around the site. The wastewater is therefore treated appropriately before discharging into the environment. Trees are planted around the wastewater ponds, and buffer strips and green areas surround the landfill.

Green Area Management:

Chiang Rai is committed to improving the city’s environment by increasing green space and bio-diversity, maintain water balance, and improve air quality. There are 41,462,100 square meters of green area and 17 public parks which occupy 393,000 square meters or 5.59 square meters per capita. Activity of large trees conservation is organized by recording a database of large plant species. Another activity is the bio-diversity conservation activity that involves 4 ecosystem management concepts as follow; 1) City Ecosystem; 2) Agricultural Ecosystem; 3) Wetland Ecosystem and 4) Mixed Deciduous Forest Ecosystem. This mission includes various government agencies and non-government sectors, universities, private sector as well as local people to participate in environment activities

Hue City – Viet Nam

Located in central Vietnam, Hue is a city blessed by rivers, mountains, forests, and surrounding lagoons .Full of vast areas of grass, water, forest landscapes, and urban trees, the density of trees in hue reaches 20 m2 to each of people, ranking it among the highest in the country basde on these metrics.

With more than 800 famous garden houses, a series of monuments, temples, tombs, and hundreds of temples covered with luscious grass and enchanting flowers, Hue is a green city with a dramatic sky filled with fresh and pure air.

The whole city has more than 62,000 trees. Every year, Hue also plants ten thousand more trees of various kinds. This number is increasing because the city plans to implement a project planting 18,000 trees in the extended defy snared area, creating a green belt in the city.”

With more than 170 species belonging to 45 different plant families, Hue exhibits a rich and diverse scene of nature. Each season in Hue brings a different characteristic of green life to the city. People of Hue love their city, and name the streets of Hue after the names of tree leaves, such as Hang Me Street, Hang Doac Street, and Phuong Bay Street.

To keep the air clean, Hue relocated several industrial zones out of the city. The year 2015 will mark the final relocation. Limiting emissions from mobile sources, Hue has developed a tram system and encourages people to use energy units and clean fuel. Since 2012, Hue has implemented the program “No Smoke City”

With the availability of natural strength, infrastructure capable of rational usage of resources and effective response to climate change, environmental protection awareness of people is advanced. Hue is the first city in Viet Nam that supported constructing its urban area in 3 levels: urban ecology, urban sustainable development and urban intelligence. Hue is a safe city environment that reflects the name that Asian Development Bank named for Hue, “Green City: Sustainable Future of Southeast Asia”.

Originating in the majestic Truong Son range, Perfume River is an important source of surface water, providing water for 75 % of all urban activities in Hue. Surface water quality at Huong river reached A level (according to Vietnam Standard Terms 08:2008 / Ministry of Natural Resources and Environment). In 2008, Hue city was the first region in the country that announced safe water supply and drinking water in the taps, the World Health Organization (WHO) selected Hue as a pilot model of “safe water” in Vietnam. Nearly 100 % of the population of Hue city reaches to the clean water. The percentage of people suffering from diseases of the digestive tract has decreased 10 times in the last 10 years.

Protecting the water sources of the city, Hue has cleared more than 1,000 households’ sampan from Huong river and resettled within the existing infrastructure. The project to improve the water resources using an investment of nearly U.S. $ 220 million loaned from the Japanese government will benefit more than half of city residents. The waste water is well managed. Medical waste water is treated before being released into the river.

Each day the city collects 200 tons of garbage. The waste is deposited at a garbage treatment factory, where modern technology processes it. Hue City has implemented a number of programs to provide waste classification training and educate the public about the dangerous environmental effects plastic bags have. Hue citizens have also been bringing about positive results with their own environmental protection activities and building Hue city as always be green and clean.
