Plans for Singapore to Reach Net Zero Emissions

Ms Anthea Ong asked the Prime Minister following the SG Climate Rally where our youths called for peak emissions by 2020, halved emissions by 2030 and net zero emissions by 2050, whether the Government is (i) including carbon emission reductions and economic decarbonisation targets in its Nationally Determined Contribution (NDC) to be updated by 2020; (ii) enhancing our upcoming NDC to reflect its highest possible ambition; (iii) declaring a climate emergency to highlight the severity of the climate crisis and (iv) setting a timeline for Singapore to reach net zero emissions.

Singapore recognises that climate change is a global and national existential issue and there is urgency for all countries to take climate action. Singapore’s Emissions Intensity (EI), that is, greenhouse gas emissions per dollar of GDP, is currently one of the lowest in the world. This is the result of choosing environmentally responsible policies as we developed, for example our vehicle control and use measures; and converting almost completely to the use of natural gas for electricity generation instead of fuel oil since the early 2000s. In comparison, many developed and developing countries are still using significant amounts of coal for electricity generation, and motor-vehicle fuel is still subsidised in several countries in our region.

We are continuing to do our part to address greenhouse gas emissions. We have pledged in our Nationally Determined Contribution (NDC) that by 2030, we will further reduce our EI by 36% from 2005 levels. We also aim to peak our emissions at 65 million tonne of CO2 equivalent around 2030. This commitment was made after carefully assessing our circumstances, and what we are able to do.

Singapore's NDC is ambitious, given our circumstances. We are a small, highly urbanised city-state, and our small land area, lack of great rivers and low and variable wind speeds limit our ability to deploy nuclear and renewable energy sources such as hydro, wind and solar energy. Nonetheless, we seek to push the bounds of innovation such as deploying floating solar photovoltaic systems on our reservoirs and offshore to make up for shortage of land area to deploy them. Such innovations have given us confidence to raise our level of ambition, to double our solar deployment target from 1 Gigawatt peak (GWp) beyond 2020 to at least 2 GWp by 2030. At this level, solar power will be able to meet around 4% of our current annual electricity needs.

Achieving our NDC will require significant whole-of-nation effort. We constantly encourage businesses and individuals to be more energy efficient. We amended the Energy Conservation Act in 2017 to require large industrial emitters to implement good energy management practices. Our policies aim to help our industries, such as petro-chemicals and electronics, be among the best-in-class globally so that we can be a responsible supplier of such products. This year, we implemented an enhanced set of Industry Energy Efficiency schemes. The Government is also making major investments to enhance public transport and active mobility infrastructure so that, by 2040, nine in 10 of all peak period journeys will be made on "walk, cycle and ride" transport modes, where "ride" refers to public and shared transport. We were the first to implement an economy-wide carbon tax in our region and did so without exemptions.

We are studying how further advances in technology can help Singapore transit earlier to a lower carbon future, and exploring the feasibility of working towards net zero emissions. For example, the Government has commissioned studies to evaluate the opportunities and challenges of carbon capture, utilisation and storage (CCUS), and "green" hydrogen, and recommend next steps for Singapore. We will also work with industry and our research community to explore pilot projects and implement research and development initiatives to improve their feasibility, and to develop the necessary frameworks to support adoption when these solutions become economically viable.

Climate change is a global issue that requires a global response, and we are committed to work with the international community to address this urgent challenge. For Singapore to do our full part, the Government cannot do it alone. We are heartened that Singaporeans, especially our youth, care deeply about this issue. A recent survey by the National Climate Change Secretariat also showed that most Singaporeans understand the importance of the issue and are prepared to take climate-friendly actions in their daily lives to address the issue. Saving electricity, using public transport and reducing waste are practical ways for Singaporeans to cut carbon emissions. We will continue to work closely with businesses, the community and individuals to do more to tackle climate change together.
