“…Aggregation for SDGs proceeds in two steps in this paper. First, based on the UN's interpretation of SDGs and other relevant studies referred to SDGs classification [21,[27][28][29][58][59][60], the 17 SDGs were aggregated into three general dimensions, i.e., economy, including SDG 8 (promote sustained, inclusive and sustainable economic growth, full and productive employment and decent work for all), SDG 9 (build resilient infrastructure, promote inclusive and sustainable industrialization and foster innovation), SDG 10 (reduce inequality within and among countries) and SDG 17 (strengthen the means of implementation and revitalize the global partnership for sustainable development); society, including SDG 1 (end poverty in all its forms everywhere), SDG 2 (end hunger, achieve food security and improved nutrition and promote sustainable agriculture), SDG 3 (ensure healthy lives and promote well-being for all at all ages), SDG 4 (ensure inclusive and equitable quality education and promote lifelong opportunities for all), SDG 5 (achieve gender equality and empower all women and girls) and SDG 16 (promote peaceful and inclusive societies for sustainable development, provide access to justice for all and build effective, accountable and inclusive institutions at all levels); and environment, including SDG 6 (ensure availability and sustainable management of water and sanitation for all), SDG 7 (ensure access to affordable, reliable, sustainable and modern energy for all), SDG 11 (make cities and human settlements inclusive, safe, resilient and sustainable), SDG 12 (ensure sustainable consumption and production patterns), SDG 13 (take urgent action to combat climate change and its impacts), SDG 14 (conserve and sustainably use the oceans, seas and marine resources for sustainable development) and SDG 15 (protract, restore and promote sustainable use of terrestrial ecosystems, sustainably manage forests, combat desertification, and halt and reverse land degradation and halt biodiversity loss). Because the three dimensions are clearly interdependent and interconnected, it could therefore be argued that some social SDGs should be categorized into the dimensions of economy and environment, and vice versa.…”
