The aim of this chapter is to provide an overview of the UN Sustainable Development Goals and their relevance for good health and well-being. Sustainable development is defined and then presented within three pillars: social, environmental and economic. The chapter examines these pillars and how they intersect with health. In 2000, out of the eight Millennium goals launched, six were directed at improving peoples’ health whilst the other two focused on environmental sustainability and partnership for development. The 17 SDGs launched in 2015 had 169 targets for 2030: often organised in the so-called Wedding Cake Model, which is examined in this chapter. Environmental issues are basic elements in this model, represented by the SDGs 6, 13, 14 and 15. Social issues are tackled through SDGs 1, 2, 3, 4 and 5. All these represent health issues as they relate to goals for “no hunger, education, healthy bodies and gender equality”. They are grouped together with SDGs 7, 11 and 16 with focus on access to clean energy, good housing, and strong institutions. The rest of the SDGs (SDGs 8, 9, 10 and 12) are defined as important for the economy (decent work, innovation and infrastructure, equity, responsible consumption and production). Partnership, SDG 17, is the overarching most important SDG, with its main focus on collaboration as a means for achieving a sustainable future. The chapter explores the SDGs for eradicating poverty, combatting inequality and stopping climate change by 2030, all of which impact sustainable good health and well-being. In conclusion, it addresses the need to take a transdiciplinary approach and forge cross-sectoral and institutional collaboration in order to achieve these SDGs.
