Regrettably, the triple global catastrophe of pollution, natural loss, and climate change coexists with the global socioeconomic problems of poverty and inequality. Temperatures are increasing at an unprecedented rate; biodiversity is disappearing swiftly, with potentially dire consequences for all of us; and pollution is becoming a global issue, killing millions of people annually and continuing to worsen. There is no normative vacuum in which the 169 targets and 17 Sustainable Development Goals (SDGs) were born or placed. They are based on international law and designed to be compliant with the commitments made in a number of soft law instruments and international agreements. There is, of course, a connection between international law and the SDGs. What kind of relationship do they have? How much and how may the SDGs and international law complement one another to improve systems integration .In an effort to leverage the relationship for global sustainability, this paper investigates these issues from two angles. First, do the SDGs play a key role in bringing together different international organizations to work toward the ultimate goal of sustainable development? Most international institutions function in relative isolation and may pursue conflicting interests since they are engrossed in their respective mandates and goals. Goal-setting, as a governance technique to prioritize, motivate, and provide direction, has been proposed by some observers as a way to improve the overall performance of current institutions in fostering sustainable development. Insofar as providing consistency to an otherwise divergent and even inconsistent set of institutional arrangements, how effective are the SDGs likely to be? Second, is it conceivable that international law will aid in the integrated implementation of the SDGs? The SDGs themselves have come under fire for lacking consistency, even though they pride themselves on being “integrated and indivisible. This is a problem since the Millennium Development Goals (MDGs) experience has demonstrated that achieving these governance goals on their own could have unforeseen consequences. While certain MDG targets were achieved, the MDGs’ spirit was not. Then, despite its fragmented structure, how and to what degree may international law integrate the SDGs and aims and aid in the achievement of long-term sustainable development.
