In March 2020, Singapore updated its NDC by changing its intensity target to an absolute target of 65 MtCO₂e/yr by 2030, or a 24% increase above 2015 levels., The update did not result in a stronger target despite the country being on track to overachieve its NDC by implementing current policies. Singapore is currently reviewing its NDC.
A 1.5°C compatible pathway would require domestic GHG emissions to peak immediately, and reach 18-22 MtCO₂e/yr by 2030, or a 56-63% reduction below 2015 levels. A fair share contribution to reduce global greenhouse gas emissions compatible with the Paris Agreement would require Singapore to go further than its domestic target, and provide substantial support for emission reductions to poor countries on top of its domestic reductions.
Singapore aims to achieve net zero emissions in the second half of the century, and halving its GHG emissions to 32 MtCO₂e/yr by 2050.,
A 1.5°C compatible pathway would require Singapore to reach zero GHG emissions or a 100% reduction below 2015 levels by 2050. Decarbonising the energy sector will drive down CO₂ levels, particularly energy combustion, as it accounts for 87% of total GHG emissions (mainly CO₂).
Policy measures that could support the transformation could include accelerating the shift in the transport sector to electric mobility, upgrading and electrifying the building and industry sectors, improving material efficiency, and significant scaling up of renewable energy including exploring options for imports, and use or export of zero emission fuels such as green hydrogen.
