The Eastern Caribbean Central Bank convened a side-event on greening the financial system at the 3rd Annual OECS Nationally Determined Contribution Finance Initiative Investment Forum in Grenada, bringing together regional governments and financial and non-financial stakeholders to deepen understanding of climate action and green finance. Discussions covered the role of green finance in sustainable development and the economic opportunity of sustainability, the role of public and private financial institutions in channelling climate finance in Caribbean small island developing states, and how development partners, central banks, financial institutions and supervisors are incorporating climate risks and opportunities into regulatory and supervisory practices. Contributors included representatives from the NDC Partnership Support Unit, Agence Francais de Development, CIBC Caribbean, the GFANZ Caribbean Chapter, the Caribbean Development Bank and the ECCB, and the wider forum ran from 31 March to 2 April under the theme 'Investing in Climate Action for a Resilient Future' with more than 200 delegates.
