Green Government

Introduced in 2006, the Public Sector Taking the Lead in Environmental Sustainability (PSTLES) initiative was aimed at improving resource efficiency within the public sector. In 2014, PSTLES 2.0 was enhanced to focus on sustainability outcomes and put in place organisational processes to manage resource use.

This year, in line with the objectives of the Green Plan, PSTLES has been refreshed and renamed as GreenGov.SG. The name “GreenGov.SG” reflects the cross-cutting role of the Government in supporting the national sustainability agenda mapped out in the Green Plan.

Under GreenGov.SG, the public sector will strive to attain ambitious sustainability targets in carbon abatement and resource efficiency, and be a positive influence and enabler of green efforts. Every public officer will be encouraged and supported to embrace sustainable practices.

GreenGov.SG has three pillars:
  • Excel with new and more ambitious targets:

    The public sector aims to peak its carbon emissions around 2025, ahead of the national target.

    By 2030, the public sector aims to reduce energy¹ and water² use by 10 percent from the average of 2018 - 2020 levels, and to reduce the amount of waste disposed³ by 30 per cent from 2022 levels.⁴

    The public sector will set targets for buildings, information technology, transport, and solar deployment that are more ambitious than the national targets.

    For all the above, the scope of GreenGov.SG will be expanded to include public sector infrastructure and operations, such as public transport infrastructure and healthcare facilities.

  • Enable a sustainable economy and green citizenry, by embedding sustainability in our core business:

    We will require Government agencies to purchase products that meet high efficiency or sustainability standards. This will apply to electrical appliances, as well as water fittings, building materials for interior use, and electric vehicles.

    We will factor in companies’ sustainability-related policies and practices when evaluating government tenders, starting with event venue and accommodation, and public waste collection contracts. We will work towards incorporating sustainability as a consideration in our procurement decisions.

    We will incorporate sustainability features at public spaces such as hawker centres and community clubs to raise public awareness. We will also educate our community on sustainability issues through our school curriculum and community programmes.

  • Excite public officers to contribute actively to sustainability in Singapore:

    There will be regular sharing sessions organised within the public sector to promote the exchange of ideas, best practices, and the latest technological solutions, so as to inspire and support public officers to champion ground-up initiatives.

    We will organise campaigns to raise awareness and encourage public officers to take simple steps to lead a more sustainable lifestyle.

As we embark on GreenGov.SG, the public sector will look to private sector leaders in the sustainability space, for innovations, best practices, and partnerships. Please refer to our media release for more details and view our infographic here

While the public sector is taking the lead, realising our goal of sustainable development is a whole-of-nation exercise. With the refreshed GreenGov.SG initiative, we hope to inspire our people and partners to embrace green practices and in turn, make sustainability a way of life, for the future and beyond.

As part of the Green Plan, GreenGov.SG will be a living plan. We will continue to refresh our targets, strategies and initiatives over time, as new opportunities are discovered. More details on GreenGov.SG will be released over the course of the year.

Together, we can chart our way towards a low-carbon and sustainable future for Singapore.

1 Energy used per unit area.

2 Water used per person per day.

3 Waste disposed of per person per day.

4 The baseline for energy and water takes into account operations under pandemic circumstances, while the baseline for waste is aligned with the timeline to implement standardised waste measurement for all public waste collection contracts.

GreenGov.SG Key Targets

Peak the public sector’s carbon emissions around 2025
  • All premises will deploy solar photovoltaics where feasible, and the public sector will increase solar deployment to 1.5GWp by 2030.
  • All cars newly procured and registered by the public sector will be clean energy vehicles with zero tailpipe emissions from 2023 onwards, and all public sector cars will run on cleaner energy by 2035.
  • All agencies will pursue efficiency improvements in their operations and buildings.
Improve the Energy Utilisation Index1 by 10 per cent by 2030 from average of 2018 to 2020 levels
  • All new and existing buildings (upon major retrofit) are to achieve Green Mark Platinum Super Low Energy (SLE) standards or equivalent, where feasible.
  • Government data centres will achieve the Green Mark Platinum standard by 2025
  • Existing public sector buildings will adopt the Guaranteed Energy Savings Performance (GESP) contracting model when embarking on chilled-water plant (including air distribution system) retrofits.
Improve the Water Efficiency Index2 by 10 per cent by 2030 from average of 2018 to 2020 levels
  • All premises will install 3-ticks Water Efficiency Labelling Scheme (WELS) fittings upon replacement.
  • All premises that are undergoing Addition and Alteration (A&A) are to achieve a minimum number of Cycles of Concentration (COC) for their cooling towers3.
  • All premises will adopt SS ISO 46001: 2019 Water efficiency management systems, if the water consumption is at least 36,000 m3/year.
Improve the Waste Disposal Index4 by 30 per cent by 2030 from 2022 levels
  • Public sector buildings with food and beverage (F&B) establishments will segregate the food waste for either on-site or off-site treatment from 2024.
  • F&B outlets at public sector buildings will not use disposables for dine-in. This will apply to new tenancy agreements signed from 2022 onwards.
  • Agencies will not provide bottled water for meetings organised within public sector premises.

1 Energy Utilisation Index is defined as the annual energy consumption per unit area.

2 Water Efficiency Index is defined as the amount of water used per person per day.

3 The requirements are 7 and 10 Cycles of Concentration for cooling towers using potable water and NEWater respectively.

4 Waste Disposal Index is defined as the amount of waste disposed of per person per day.
