Singapore aims for 2028 peak emissions

??This week: Singapore has set 2028 as the year when its greenhouse gas emissions are expected to peak, making the next three years a critical period for setting up the country’s coming energy transition.

Singapore released two progress reports on its emissions over the past week. The first is a Biennial Transparency Report , which provides updates on Singapore’s whole-of-country performance on its climate targets under the Paris Agreement. The second is the GreenGov.SG report , which covers emissions by the Singapore public sector.

Here are some takeaways.

Greater transparency

The new reports contain new information that provide greater insight into the decarbonisation metrics and strategies that the Singapore government is using.

For example, the GreenGov.SG report includes waste data for the first time, showing that total waste disposed at government facilities increased 1.3 per cent to 218.7 million kilogrammes in the year ended March 2024 as activity levels at tenanted industrial areas and some public-facing locations returned to normal. The reporting period is referred to by government convention as fiscal year 2023.

However, when averaged out, the amount of disposed waste worked out to 0.38kg per person per day, which was 9.1 per cent lower than the year before. The public-sector target is to reduce the average to 0.29kg per person per day by 2030.

Perhaps of greater significance are projections in the Biennial Transparency Report that Singapore will hit peak net emissions of 61.92 million tonnes of carbon dioxide equivalent (MtCO2e) in calendar year 2028. This the first time that Singapore has specified 2028 as the year in which it expects peak emissions. Previous disclosures have put the peak between 2025 and 2028.

Peak emissions include offsetting 2.51 MtCO2e of emissions per year through carbon credits, without which emissions in 2028 could reach 64.43 MtCO2e.

Past 2028, national emissions are expected to begin declining to around 60 MtCO2e with offsets in 2030, en route to a goal of net zero by 2050. It means that, on average, Singapore will have to cut emissions by about 3 MtCO2e per year for 20 years after 2030, or about 5 per cent of 2030 emissions each year, all while presumably growing the economy.

For 2025, Singapore expects to report 59.7 MtCO2e of emissions with offsets, and 62.21 MtCO2e without.

Energy priority

Emissions from energy-related activities are the largest source of national emissions for Singapore, accounting for 84 per cent of the total in 2022, excluding offsets. That is the latest year with actual reported emissions numbers.

With only three years to peak emissions, steps to decarbonise the energy segment is likely to be a top priority for Singapore in the next few years. Past 2028, the energy landscape could undergo major changes as Singapore’s energy mix changes.

For the purpose of the Paris Agreement commitments, the energy segment covers a broad range of activities, including energy industries, manufacturing industries and construction and transport. Waste-to-energy incineration is also included in the energy segment where the waste is fossil-based. Biomass incineration for energy is excluded.

A key pillar of the energy transition is importing low-carbon electricity, with six Gigawatts of imports targeted by 2035. Singapore has started entering into import agreements, with 10 projects granted conditional approvals, of which five have progressed to conditional licences. The setting up of infrastructure to enable imports, such as a regional grid, remains an ongoing challenge.

Singapore is also investing in and exploring other fossil fuel alternatives, including a deal with the United States to study nuclear technology, and research and tests into hydrogen-based fuels.

One aspect of the energy transition that has not received much discussion is the phasing out of fossil fuel-based energy facilities. In order to bring emissions down, Singapore cannot merely add low-carbon sources to its energy mix; it must also stop burning fossil fuels for energy.

The waste-to-energy sector could be especially challenging. Waste incineration in Singapore not only produces energy, but also reduces the need for landfills in a land-starved country. Carbon capture could potentially mitigate emissions from this sector, but the efficacy of carbon capture and sequestration is still uncertain. Getting to net zero means that Singapore must also pursue a robust waste reduction strategy.

Whole-of-country effort

While the Singapore government holds significant influence over some of the largest emitting segments of the economy, its leverage can only go so far.

The choices of individuals and the private sector, in particular, are particularly important. For example, the government could invest in cleaner waste treatment solutions, but the cost of doing so is greatly mitigated if individuals and businesses make more responsible consumption choices.

The GreenGov.SG report takes great lengths to highlight actual solutions taken by the public service to mitigate emissions and waste. An interesting case study discusses how the Energy Market Authority fit two workstations instead of one into each cubicle in order to fit an expanding department. The move led to 70 per cent savings, the report says. It would be interesting to know how the department’s staff feel about the sardine-fication of their office.

All the same, it’s clear that the report is intended to not only provide a progress report, but also to serve as an educational resource for organisations looking to embark on the same journey.

Indeed, in a foreword, Minister for Sustainability and the Environment Grace Fu writes: “We have shared some of the challenges we faced and our experiences, which we hope are useful to organisations or groups looking to implement sustainability strategies”.

1. The climate finance fund being negotiated at COP29 will probably fall short of the US$1 trillion needed to support developing countries’ climate action, says political research outfit BMI.
2. Paris-based asset manager Mirova plans to hire staff in Singapore for its blended finance, green bonds and multi-thematic strategies.
3. A few carbon projects could test the newly approved Article 6.4 carbon credit methodologies in the next six to 12 months, says Sharad Somani, head of infrastructure advisory in the Asia-Pacific at KPMG in Singapore.
4. Singapore and Zambia have signed a preliminary deal on carbon credit trading between the two countries.
5. Battery energy storage systems can complement renewable energy sources to ensure reliable and flexible power supply, says Rodrigo Hernandez, ENGIE South East Asia’s head of solar for commercial and industrial projects.
