Small Island Developing States (SIDS) stand on the frontline of the global climate crisis, facing a convergence of environmental, economic and institutional challenges that disproportionately threaten their sustainable development pathways. Despite contributing minimally to global greenhouse gas emissions, SIDS have demonstrated strong climate ambition through their Nationally Determined Contributions (NDCs).

The Caribbean is one of the most climate-vulnerable and disaster-prone regions. The region’s vulnerability stems from its geography, topography and several socio-economic factors. Despite these challenges, Small Island Developing States (SIDS) in the Caribbean have committed to ambitious Nationally Determined Contributions (NDCs) under the Paris Agreement, covering renewable energy transitions, ecosystem protection, coastal resilience, and climate-resilient infrastructure.

For International Women’s Day 2026, the United Nations calls for urgent action on “Rights. Justice. Action. For ALL Women and Girls,” reminding the world that gender equality remains unfinished business. This year’s theme is a rallying cry to dismantle entrenched barriers, accelerate justice for women and girls, and anchor all climate, development, and governance efforts in human rights and gender equity.

At COP30 in Belém, Brazil, the global climate finance architecture and the need to accelerate the flow of both public and private capital to climate-vulnerable nations was high on the agenda for Commonwealth member countries. This is particularly critical for Small Island Developing States (SIDS), Least Developed Countries (LDCs), and other vulnerable countries which continue to face persistent barriers to accessing finance at scale.

As COP30 in Belém, Brazil, wound down, the Commonwealth Youth Climate Change Network (CYCN) demonstrated that young people are not passive observers, but active drivers of policy innovation, justice, and climate ambition. In their statement to COP30, they called upon Commonwealth member countries to not only mainstream youth participation in national climate governance but also equip young people with the skills needed for climate negotiations at international forums.

Climate finance is not aid. It is the smart thing to do to protect people and planet. Not only must the world change the ways of production, consumption, trade and investment to reduce greenhouse gas emissions and strengthen adaptation; it must also change the ways in which climate finance is designed and delivered to foster inclusivity and gender-responsive climate action.

Young people are increasingly recognised as vital agents of change in advancing climate action. This means including them in climate-policy decision-making and implementation. However, many young people - particularly in Small Island Developing States (SIDS) and other climate-vulnerable countries - continue to face barriers such as limited access to climate finance, insufficient green skills, and exclusion from decision-making processes.
This framework describes how a National Data Hub for Gender and Climate Information – a centralised, policy-linked platform that collects, harmonises and disseminates gender-responsive climate data – could be implemented. This transformative initiative would enable the Government of Nigeria to design inclusive and effective responses to mounting climate risks, strengthen institutional accountability and ensure that Nigeria’s climate actions reflect the lived realities of all of its citizens.

Nationally Determined Contributions (NDCs) are the cornerstone of the Paris Agreement and the primary mechanism for communicating national climate ambitions and emission reduction targets. While not required, many countries have used the NDC to outline their adaptation goals and needs.

Operating in its tenth year, the “Hub” has deployed 40 climate advisers and trained over 3,400 government officials, climate change professionals and young people to navigate the complexities of climate finance.
