GreenGov.SG Report FY2024
6 October 2025
Singapore, 6 October 2025 — The Ministry of Sustainability and the Environment (MSE) has published the GreenGov.SG report FY2024, which details the public sector’s environmental sustainability performance from 1 April 2024 to 31 March 2025.
2 The public sector is making steady progress towards achieving its energy, water, waste, and solar deployment targets. It is also taking steps to maximise resource efficiency and reduce emissions from its infrastructure and operations, even as essential public services continue to grow to serve the needs of our population and economy.
Carbon Emissions
3 In FY2024, the public sector emitted around 3.6 million tonnes of carbon dioxide equivalent, a decrease of 1.9% from FY2023 and 9.5% from the FY2020 baseline. Scope 1 emissions[1] in FY2024 were 27.9% lower than the baseline due to the decommissioning of Tuas Waste-To-Energy (WTE) Plant in 2022. Scope 1 emissions decreased by 8.4% from FY2023 to FY2024 due to the operation and maintenance schedule of the remaining Tuas South Waste-to-Energy (WTE) plant, which resulted in reduced waste processing capacity, as well as variations in the composition of waste incinerated. We expect our Scope 1 emissions to rise again when our new WTE plant, the Integrated Waste Management Facility, becomes operational in 2027.
4 Scope 2 emissions[2] increased by 2.0% from FY2023 due to the expansion of public infrastructure in the transport and healthcare sectors. The Thomson-East Coast Line (TEL) Stage 4 opened in June 2024, adding seven new stations and 10.8 kilometres to the rail network. Woodlands Health Campus began operations in July 2024, and will eventually provide 1,000 more acute and community hospital beds to serve residents in the north. Tan Tock Seng Hospital Integrated Care Hub also saw a first full year of operations since it officially opened in March 2024. More growth is expected as Singapore’s public infrastructure expands to serve our people better. We are taking deliberate steps to maximise resource efficiency in both new and existing facilities, whilst accelerating renewable energy deployment and imports.
Energy Utilisation and Water Efficiency Index
5 The public sector’s total electricity use in FY2024 was 5,623 GWh, which was a 2.0% increase from FY2023 and 1.1% increase from the average FY2018-FY2020 baseline. The public sector’s electricity used per unit area, or Energy Utilisation Index (EUI), in FY2024 was 112.5 kWh/m2, which was a 0.4% decrease from FY2023 and a 3.0% decrease from the FY2018-FY2020 baseline. This is due to systematic efforts to retrofit older buildings to Green Mark Platinum standards, adopt better designs, as well as deploy solar and smart building technologies.
6 The public sector’s water use in FY2024 was 32.9 billion litres, which was a 3.3% decrease from FY2023, and a 3.7% decrease from the FY2018-FY2020 baseline. The public sector’s Water Efficiency Index (WEI) in FY2024 was 55.9 litres of water used per person per day, which was an 8.1% decrease from FY2023, and a 13.5% decrease from the FY2018-FY2020 baseline. This improvement was due to efforts from proactive leak detection using smart monitoring and user reporting systems, rethinking water-intensive processes, and innovative water reuse initiatives.
Waste Data
7 The public sector’s waste disposed of in FY2024 was 210.1 million kilograms, which was a 2.2% decrease from FY2023 and a 2.6% decrease from the FY2022 baseline. The public sector’s Waste Disposal Index (WDI) in FY2024 was 0.349 kilograms of waste disposed of per person per day, which was a 4.8% decrease from FY2023, and a 13.1% decrease from the FY2022 baseline. The decrease is due to comprehensive waste management strategies across the 3R framework, such as reducing unnecessary packaging, reusing decommissioned assets, and recycling food waste across public sector facilities.
GreenGov.SG Reporting a Continuous Work in Progress
8 The GreenGov.SG report is released annually to provide an update of the public sector’s performance on greenhouse gas emissions, energy consumption, water use, and waste disposed. It covers the public sector’s assets in Singapore, including office buildings, healthcare facilities, schools, public utilities installations, public transport infrastructure, and vehicles. The report also sets out the public sector’s key strategies and initiatives to enhance environmental sustainability.
9 GreenGov.SG was introduced in 2021 as a key enabler of the Singapore Green Plan 2030. Under GreenGov.SG, the public sector has set targets to achieve net zero emissions around 2045, five years ahead of Singapore’s national target of net zero by 2050. The public sector has also committed to reducing energy and water use by 10%, and waste disposal by 30% by 2030. Through GreenGov.SG, the public sector also aims to inspire businesses and communities to contribute towards advancing Singapore’s long-term sustainability.
10 The public sector recognises that reporting is an evolving process that benefits from shared learning and continuous refinement. The GreenGov.SG report shares both the challenges and innovative sustainability solutions implemented across public sector agencies. These real-world examples and lessons learnt will support organisations and businesses in developing their sustainability strategies and overcoming similar implementation challenges.
