The Sixth Assessment Report of Inter-Governmental Panel on Climate Change (IPCC) has highlighted the urgency of accelerated climate actions harnessing synergies and minimizing trade-offs with various SDG. This calls for a clear understanding of linkages between climate goals and other SDGs at national level for formulating synergistic policies and strategies and developing different sectoral programs and coherent cross-sectoral policies. This is even more important for least developed countries such as Nepal where these linkages are less understood and development challenges are multifaceted. In this context, this paper aims to evaluate potential synergies and trade-offs among selected SDGs and their associated targets in Nepal in a linear pairwise comparison. Synergies and trade-offs related to climate action (SDG 13), access to energy (SDG 7), sustainable consumption and production (SDG 12), and life on land (SDG 15) have been evaluated using historical data for the period from 1990 to 2018 employing a mixed methods approach. Network analysis to map the conceptual linkages between the SDGs and their targets was combined with the advance sustainability analysis (ASA) to quantitatively evaluate the synergy and trade-offs between SDGs. The results illustrate the presences of a continual trade-off between emission reductions targets of SDG 13 with per capita energy consumption and share of renewable energy of SDG 7, land use for agricultural production target of SDG 12, and forest area target of SDG 15. This indicates that climate action is strongly interlinked with GHG emissions from economic activities and energy consumption. The results of the study represent a valuable input for the policy makers, supporting coherent and sustainable development planning as Nepal plans to graduate to a middle-income country.

This paper develops an Index of Sustainable Economic Welfare for Spain from 1970 to 2012 and seeks to update valuation approaches to a number of items. Two approaches have proven particularly controversial over recent decades; the costs of energy depletion and of climate change. The valuation implications in measuring present welfare have proven problematic, as both include future sustainability consequences arising from resource depletion and environmental impacts. This study includes a ‘ transition cost ’ approach to energy depletion, a modified approach to costs of climate change and water pollution, and removes the cost of ozone depletion. The results illustrate that while GDP per capita increased significantly, the ISEW per capita shows a widening gap. Household labour contributes strongly, but income distribution, energy depletion and costs of climate change limit improvement. Sensitivity analysis shows that accumulating climate change costs and escalating energy depletion costs have significant effects. Nevertheless, the new valuation approaches do not alter conclusions that welfare has shown little improvement. The ISEW provides a useful alternative to current indicators such as GDP subject to awareness of limitations. It is a measure of welfare that uses sustainability accounting methods when estimating costs, but is not an indicator of whether welfare is actually sustainable. [ABSTRACT FROM AUTHOR]
