At the United Nations Climate Change Conference in Durban in 2011, all countries agreed to start negotiations on a new climate change framework beyond 2020. As a responsible global citizen, Singapore will do our part to reduce emissions, while ensuring that we continue to grow and prosper. Singapore will do our part... The Inter-Ministerial Committee on Climate Change (IMCCC) will study how Singapore can stabilise our long-term emissions. Its work will build on Singapore’s past and ongoing efforts in sustainable development. The clean and green Climate change affects us all, including Singapore... living environment we enjoy today is the result of the high priority we have placed on protecting The global climate is changing.

For instance, temperature and sea levels are expected to rise if we generate about 80% of our electricity from carbon emissions from human activities continue natural gas—the cleanest form of fossil fuel. to grow unchecked, and extreme weather events are likely to become more intense and frequent. Efforts to reduce our long-term emissions will be challenging. Our small size limits our ability What does this mean for Singapore? Extreme to draw on alternative energy such as solar, weather events can lead to changes in rainfall wind or nuclear. Nonetheless, we will enhance patterns, resulting in more intense rainfall or energy efficiency efforts and develop low carbon drier periods. Flood and water management technologies to overcome current constraints. will be of even greater importance for Singapore. In addition, more frequent extreme weather events may lead to volatile global food prices and disruptions to business supply chains. This will affect business activities in Singapore and our food imports. 4 FOREWORD—THE CLIMATE CHANGE IMPERATIVE Preparing Singapore for climate change... A home that is flourishing and enduring… Apart from reducing emissions, we need to adapt To achieve our goal of a home that is to the impact of climate change. We will invest flourishing and enduring, the people, private in new capabilities in climate science to achieve and public sectors need to work in close a deeper understanding of our vulnerabilities, partnership. The Government will play its part and develop appropriate adaptation solutions by setting the policy framework, putting in place to protect Singapore against the risks posed by appropriate incentives, facilitating capability climate change. development efforts, and easing the transition. The implementation of policies will be paced so At the same time, Singapore is well positioned that our economy and our people can adapt to to tap the economic opportunities arising from the new circumstances. climate change.

The IMCCC will drive Singapore’s efforts to realise our vision of a climate resilient global city poised To rise to the challenge, we need to be pragmatic for green growth.

What does it mean for Singapore, now and in the future? What have we been doing about it, and what can be done going forward? This National Climate Change Strategy document seeks to address these vital questions. It outlines current thinking about climate change and its implications for Singapore. It also highlights the initiatives and strategies we are pursuing to prepare for the challenges that climate change poses. 6 OVERVIEW—GLOBAL MISSION, NATIONAL VISION, LoCAL ACTION Impact of Climate Change Scientists and experts around the world have intense storms and tropical cyclones, flooding and yet to fully agree on how quickly climate- prolonged droughts in recent years.
