With the introduction of the Sustainable Development Goals (SDGs) in 2015 by the United Nations Development Programme (UNDP), Sri Lanka has given priority to the SDGs in its main development agenda and attempting to achieve them by working towards the fulfilment of the basic needs and improving the living standards of the people, progressively alleviating poverty, eliminating all forms of discrimination and inequalities and establishing a society based on social justice and human security. In this regard, Sri Lanka has both prospects and obstacles in the achievement of SDGs. This paper has paid attention to explore the available opportunities and challenges in the journey of achieving SDGs by adopting the Blue-Green economic provisions in Sri Lanka. Additionally, it has also been attempted to present some effective recommendations to overcome those impediments since identifying effective solutions is equally important in finding ways to overcome those impediments. Using the existing secondary literature available in the forms of literary books, journal articles and reports, this study has found that it is a timely requirement of the Government of Sri Lanka (GoSL) to adopt the Blue-Green economic provisions to get back the current unsustainable development of Sri Lanka on the right track and achieve the SDGs by 2030.

Blue-Green economic principles are considered an important parameter to achieve sustainable development. The United Nations' mandated Sustainable Development Goals (SDGs) also emphasize the importance of adopting Blue-Green economic principles in national development policies to ensure the sustainability of socio-economic development. This paper has paid attention to examine the conceptual nexus between sustainable development and the Blue-Green economy as a condition for achieving Sustainable Development Goals. Using the existing secondary literature available in the forms of literary books, journal articles and reports, this study has found that focusing and adopting conceptual bases of the Blue-Green economy is an unavoidable aspect of achieving many of the important Sustainable Development Goals which are fundamental for achieving other goals.
