Responding to climate change
Singapore is a small, alternative-energy disadvantaged country with no natural resources. This makes addressing climate change challenging as we have to think and work harder to decarbonise our energy sector.
We took early action to switch to natural gas, the cleanest fossil fuel, for our electricity needs. We are also maximising our solar deployment. To overcome our land constraints, we are investing in innovative solar technologies such as floating solar PV systems on our reservoirs and at sea. These will number among the world’s largest when completed.
Although Singapore contributes only 0.11% of global emissions, we are committed to fulfil our ambitious climate pledge so that we can contribute meaningfully to the global fight against climate change. To mitigate climate change, we have a comprehensive suite of measures to reduce emissions across all sectors, for example by greening our energy, our transport, and our towns.
We are also protecting Singapore from the impacts of climate change. Since 2011, we have spent around S$1.8 billion on drainage improvement works to bolster our flood resilience. We will spend another S$400 million to upgrade our drains over the next two years. To protect against rising sea levels, we have raised minimum land reclamation levels, and require new buildings and developments to be built at least 4 metres above mean sea level. At the national level, we will embark on long-term plans to strengthen our coastal defences. We are studying innovative solutions, such as the use of polders and reclaiming a series of islands offshore. This will be a costly undertaking, perhaps requiring S$100 billion or more over the next 50 to 100 years. But it is necessary for our island nation’s survival.
