In 2015, the United Nations established 17 Sustainable Development Goals (SDGs) to create a socially inclusive and environmentally sustainable future for all. However, progress toward these goals has been severely hindered by economic crises, driven by both internal and external factors, including the debt crisis and the COVID-19 pandemic. With SDG progress falling short of expectations, it is crucial to assess the extent to which each SDG has been impacted to propose targeted corrective measures. Additionally, immediate solutions are needed to address financial constraints and ensure the realisation of the SDGs by 2030. There is a lack of studies exploring pathways for the concurrent achievement of SDGs and Sri Lanka is no exception. Quantitative goal-seeking scenarios can help identify enabling conditions while accounting for the synergies and trade-offs between the SDGs. In such a context, this study will examine various scenarios for SDG achievement in Sri Lanka and explore potential financing instruments and options to bridge the funding gap.
