Singapore has achieved impressive economic growth over the last half-century. This chapter provides an overview of the major sustainability challenges Singapore has experienced and the policies that have been adopted to address them, particularly in the areas of land use, transportation, waste management, water, and energy. It argues that Singapore has been successful in addressing these challenges owing to sound long-term vision and planning as well as flexibility in the implementation of the policies to tackle them. The chapter provides some discussion on policy options, challenges, and opportunities for making Singapore more sustainable and liveable. Leaders of Singapore have recognised land scarcity as one of Singapore’s most serious challenges since its independence. Therefore, efficient land use with sound planning has been among the most important policy objectives to enable sustainable growth in Singapore.

The resounding victory of the People's Action Party (PAP) in the 2015 Singapore general elections surprised many observers. Several observers had considered the previous election, held in 2011, to be the new normal in Singapore politics, with the Workers' Party being the first opposition party to win a Group Representative Constituency (GRC). Instead of its popular vote sliding from 60% in 2011, the PAP secured almost a 10% increase in its fortunes. Analysts have spoken about PAP's hard work and the opposition's failures when commenting on the ruling party's success; this article, however, points out how Singapore's electoral system, especially the GRC, continues to favour the ruling party and why it should be rethought. Introduced in 1988, the scheme ensures minority candidates (non-Chinese) are voted into parliament. Candidates contesting in a GRC form a team of Members of Parliament (MPs) with at least one minority candidate in each team. This article argues that the 2015 election results proves that Singaporeans no longer vote along ethnic lines, and non-Chinese MPs have comfortably led the GRCs and won in Single Member Constituencies. To be sure, the GRC scheme does new PAP candidates a disfavour: it weakens their legitimacy with voters, since they remain under the shadows of senior PAP candidates and cannot win elections on their own accord.
