This article addresses the continuing quest for effective sustainable development laws, policies and other measures, in the context of the international objective of achieving the UN Sustainable Development Goals by 2030. It addresses these issues both in general and in the specific context of climate policy. It focuses on exploring the results presented by other authors that discuss these matters in depth, with particular attention to the five problem areas: uncertainties in dealing with concerns of precaution and possible future impacts; the role of nature in society; international treaties; interlinkages among the SDGs; and the challenges of evaluation and feedback.
