Singapore faces disproportionate climate risks despite minimal global emissions, driving innovative solutions like solar energy expansion and hydrogen investment. The country’s pragmatic approach includes domestic renewable energy growth, international carbon market participation, and adaptation strategies to address irreversible climate impacts.
Singapore, a densely populated and low-lying island nation, faces significant climate challenges despite contributing only 0.1 per cent of global greenhouse gas emissions. The country is highly vulnerable to climate change impacts, including volatile rainfall, heavier downpours, and rising flood risks.
These pressures threaten infrastructure, public health, and economic stability. Singapore’s location near the equator ensures strong sunlight year-round, but limited land availability restricts large-scale solar deployment. To overcome this, the country has focused on maximizing available surfaces by installing solar systems on rooftops, reservoirs, and industrial spaces. Solar energy remains Singapore’s most viable domestic renewable energy source, with capacity growing steadily.
The nation has already surpassed its initial deployment target of 2 gigawatt-peak (GWp) and continues to expand, with projects like the Tengeh Reservoir installation showcasing innovative use of water bodies. The Tengeh system, spanning about 45 hectares with over 120,000 solar panels, generates enough energy to support water treatment operations and reduces carbon emissions by around 32 kilotonnes annually, equivalent to removing 7,000 cars from the road.
However, even with widespread solar deployment, Singapore’s electricity demand remains partially unmet, necessitating exploration of alternative energy sources. The government is investing in hydrogen as a potential energy carrier, along with technologies like carbon capture, utilisation, and storage. Transitioning to lower emissions comes with challenges, particularly for energy-intensive sectors that must upgrade equipment, adapt processes, and comply with stricter reporting requirements while maintaining competitiveness. To support businesses, Singapore offers schemes to improve energy efficiency and adopt sustainable practices.
Beyond domestic efforts, companies can leverage global carbon markets under Singapore’s carbon tax framework, offsetting up to 5 per cent of taxable emissions after reducing their own operational emissions. The country collaborates with international partners through the Coalition to Grow Carbon Markets and has signed bilateral agreements to ensure robust standards, fostering confidence in global carbon markets. Despite emission reductions, some climate effects are irreversible, necessitating adaptation strategies.
Singapore’s climate challenge is complex, driven by limited energy options, rising physical risks, and an open economy. Progress is being made across multiple fronts, including solar expansion, research into future energy sources, business support, and climate adaptation investments. The approach is pragmatic, forward-looking, and long-term, recognizing that sustained efforts from government, businesses, and society are essential to manage climate change effectively
