Singapore Targets Significant Emission Reductions by 2035, Emphasizes Technological Innovation

Singapore has committed to reducing its greenhouse gas emissions to between 45 and 50 million tonnes of carbon dioxide equivalent by 2035, a notable decrease from the projected 60 MtCO₂e in 2030. This pledge, submitted to the United Nations Framework Convention on Climate Change on 10 February 2025, aligns with the nation’s broader strategy to achieve net-zero emissions by 2050.

Achieving these ambitious targets will necessitate the development and deployment of advanced technologies. The Energy Market Authority has announced plans to co-fund feasibility studies on carbon capture and storage for power generation. These studies will explore both post-combustion carbon capture for combined-cycle gas turbines and pre-combustion carbon capture to produce hydrogen. Such initiatives are crucial for mitigating emissions from natural gas, which currently accounts for over 95% of Singapore’s electricity generation.

In addition to CCS, Singapore is investing in low-carbon energy imports. The nation aims to import up to 6 gigawatts of low-carbon electricity by 2035, potentially supplying around 30% of its energy needs. Conditional approvals have been granted for projects in Australia, Cambodia, Indonesia, and Vietnam. To support these ventures, Singapore is prepared to offer 30-year import licences, providing companies with the long-term security needed to justify substantial investments in infrastructure.

The government is also focusing on enhancing energy efficiency across various sectors. Initiatives include the Genco Energy Efficiency Grant Call, which encourages power generation companies to adopt energy-efficient technologies by co-funding up to 50% of their projects. In the transportation sector, efforts are underway to transition to cleaner energy sources. All new public bus purchases are now cleaner energy buses, including electric or hybrid models, with a target to replace all existing diesel buses by 2040. Additionally, the cycling path network is set to expand to 1,300 km island-wide by 2030, promoting sustainable urban mobility.

However, the path to these goals is fraught with challenges. The success of these initiatives hinges on the successful development and implementation of new technologies, as well as sustained global cooperation. The high upfront costs associated with infrastructure development, such as large-scale solar farms, battery storage systems, and extensive power cables for energy imports, present significant financial hurdles. The government acknowledges these challenges and is taking steps to mitigate them, including offering long-term import licences and co-funding feasibility studies.
