Public sector carbon emissions decline in 2023

It slipped by 0.2% from 2022.

The public sector emitted 3.6 million tonnes of carbon dioxide in 2023, a 0.2% decrease from 2022, according to GreenGov.SG report.

This was driven by a decrease in Scope 1 emissions from the Tuas South Waste-to-Energy Plant, which offset the increase in diesel consumption as bus service mileage increased from improved bus frequencies and coverage.

The report, however, found that Scope 2 emissions increased by 0.3% mainly due to a full year of operation of the Stage 3 of the Thomson-East Coast Line and newly-opened healthcare facilities. Still, the public sector’s 2023 emissions remained 6.8% lower than the 2020 baseline.

The total electricity use in 2023 was 5,449 gigawatts per hour, a 1.5% increase. The Energy Utilisation Index increased by 1% to 112.6 kilowatt-hours per square metre, due to increased electricity use across public sector premises.

As for water, the public used 3.4 billion litres, which was a 0.4% decrease. The sector’s water use per person per day was 60.7 litres, reflecting a 4% decrease due to improved water management.

Moreover, the public disposed of 218.7 million kilograms of waste last year, a 1.3% growth due to increased levels of activity and higher footfall at public facilities. Waste disposed per person per day increased by 9.1% to 0.380 kilograms driven by collective efforts to reduce waste across public premises.

Reaching the people who run Asia's businesses is harder than it used to be.

Inboxes are crowded. Attention is short. The executives you most want to reach — the founders, CFOs, and operators who actually move budgets — are the hardest to find through the usual channels. If you're building a company, a category, or a reputation, you already know this.

We've spent twenty years building the room they read. Singapore Business Review is where senior decision makers in Singapore and across Southeast Asia come for business coverage they can't get elsewhere — in print, online, and in person at the summits and roundtables we host across seven markets.

If you have something these readers should know about — a point of view worth publishing, a product worth their attention, an event worth their time — we'd like to hear what you're trying to do.
