About the entity

PUB Singapore's National Water Agency
PUB is a statutory board under the Ministry of the Environment and Water Resources. It is the national water agency that manages Singapore’s water supply, water catchment and used water in an integrated way.

PUB, Singapore’s National Water Agency, has established a Green Financing Framework to fund planned and future green projects that support PUB’s sustainability efforts. As part of a new S$10 billion Multicurrency Medium Term Note Programme*, PUB also plans to launch its inaugural green bonds later this month. This will mark another milestone in PUB’s journey to advance sustainable development and climate action.

The establishment of PUB’s Green Financing Framework will contribute towards Singapore Green Plan 2030, a whole-of-nation movement to build a sustainable future for Singapore. It is also a boost to PUB’s continuing efforts and innovation to ensure a resilient and sustainable water supply for Singapore, which remains critical amidst the challenges of climate change.​

Our Commitment towards Environment Sustainability​​

As the nation’s water agency, sustainability has always been central to PUB’s mission. Over the years, we have closed the water loop and built new sources of water through NEWater and desalination. We now operate the water system as an integrated whole to strengthen Singapore’s water security.​

Looking ahead, climate change will result in more extreme weather events that can impact our water resources. At the same time, water demand is projected to almost double by 2060 in tandem with economic and population growth. The need to tap increasingly on NEWater and desalination will also increase our energy needs to meet growing water demand.​​​

PUB’s challenge is to ensure our water system remain resilient and sustainable, while mitigating our impact to the environment. Since 2021, PUB has established a Sustainability Framework ​to guide and codify our approach, so as to realise our vision for a greener water system for Singapore. We seek to deliver our mission effectively and responsibly amidst the challenges of climate change, and support the national agenda for a sustainable future.

PUB's Gr​​een Financing Framework

The establishment of PUB’s Green Financing Framework is an important step in our endeavour. The framework will ensure that the green bonds issued adhere to market best practices, including strong governance and clear eligibility criteria to evaluate and identify green projects that have a positive impact on the environment.​​​​​

PUB’s Green Financing Framework is aligned to the International Capital Market Association (ICMA) Green Bond Principles 2021 and the ASEAN Capital Market Forum (ACMF) ASEAN Green Bond Standards 2018. Our projects will advance goals in sustainable water and wastewater management, and renewable energy. Projects must achieve reduction in greenhouse gas emissions and contribute to decarbonisation, or show improvements to the environment to qualify as green projects.​​​​​​

Potential projects eligible to be financed with proceeds from green bonds, subject to further evaluation, include:

  • Promoting Energy Self-Sufficiency - Tuas Water Reclamation Plant:​ the plant is currently under construction and will be co-located with National Environment Agency’s (NEA) Integrated Waste Management Facility (IWMF) to collectively form Tuas Nexus. It marks Singapore’s first initiative to harness potential synergies of the water-energy-waste nexus by integrating used water and solid waste treatment processes to be energy self-sufficient. This is expected to result in carbon savings of more than 200,000 tonnes of CO2 annually, equivalent to taking 42,500 cars off Singapore’s roads.​
  • Producing Clean Water from Clean Energy - Floating Solar PV Projects: PUB has installed both land-based and floating solar photovoltaic (PV) systems on reservoirs, which has offset 8% of our total energy needs. The clean energy generated at PUB’s first large scale floating solar farm project at Tengeh Reservoir is sufficient to power all our local treatment plants for drinking water, equivalent to removing 7,000 cars from the roads. We will continue to assess suitable sites to deploy floating solar systems in an environmentally sensitive manner. Feasibility studies are being planned for two other large-scale floating solar PV systems at Lower Seletar and Pandan Reservoir.​

​*Net proceeds from the issuance of Notes under the Programme will be used for general corporate purposes, including refinancing of borrowings, financing general working capital and capital expenditure requirements of PUB.
