Singapore's public sector emitted 3.6 million tonnes of carbon dioxide equivalent for the fiscal year (FY) 2023, a 0.2-percent decrease from FY2022, according to an official report issued Monday.

The "Greengovsg Report" released by the Ministry of Sustainability and the Environment detailed the public sector's environmental sustainability performance from April 1, 2023, to March 31 this year.

The public sector's total electricity use in FY2023 was 5,449 GWh, up 1.5 percent from FY2022. Meanwhile, the water use dropped 0.4 percent to 33.4 billion liters.

Singapore's public sector produced 218.7 million kg of waste in FY2023, a 1.3-percent increase from the previous fiscal year, due to more activities and higher footfall at public sector facilities after COVID-19.

The public sector sets a net-zero target around 2045, five years ahead of Singapore's national target by 2050.
