St. Lucia has been a leader among vulnerable Caribbean states in prioritizing a response to climate change, both nationally and in international fora. Its Nationally Determined Contribution (NDC) outlines a balanced mitigation strategy backed by costed investment plans, and a qualitative adaptation strategy with identified priority sectors. This paper takes stock of St. Lucia’s plans to manage climate change, from the perspective of their macroeconomic implications. It suggests macro-relevant reforms that could strengthen the likelihood of success of the national strategy and identifies policy gaps and resource needs.
