COP28 Must Address Trillion-Dollar Climate Finance Gap for Developing Nations

As global leaders convene at COP28 in Dubai, the UN's first global stocktake confirms current greenhouse gas emissions are incompatible with Paris Agreement pathways, while developing and least-developed countries face a widening climate finance gap estimated between US$194 billion and US$215 billion annually for adaptation alone. IEEFA analysis calls for a structural overhaul of international climate finance to prioritise grants, concessional loans and a genuine separation from official development assistance.

Developed countries claim they may have finally delivered the US$100 billion per annum climate finance commitment made at the 2010 Cancun Conference in 2022, twelve years after the pledge. However, only one-quarter of reported flows arrive as grants; the remainder is structured as loans, with a significant portion in non-concessional instruments. Between 25% and 30% of the reported climate finance in 2021 was counted as climate-specific rather than additional to ordinary development cooperation. Mitigation received 59% of public climate finance directed to developing countries in 2021, while adaptation received only one-third.

The IEA has identified tripling global renewable energy capacity and doubling energy efficiency as central pillars of achieving required emissions reductions this decade, requiring annual clean energy investment to reach US$4.3 trillion by 2030. Of this, emerging and developing economies need US$2.26 trillion annually. The combined GHG mitigation indicated by current national climate plans will deliver only a 2% reduction relative to 2019 levels by 2030, against the 43% required under the 1.5 degrees Celsius pathway. A climate-vulnerable country like Bangladesh incurs US$1 billion annually in cyclone-related losses and could see GDP contract 9% from severe flooding.

IEEFA calls on COP28 to fully resolve disagreements on the differentiation of climate finance from ODA, increase grant components, scale concessional lending and rebalance allocations between adaptation and mitigation. Operationalising the loss and damage fund — removing access complexities and ensuring it reaches the most vulnerable countries — is flagged as an urgent priority. IEEFA also highlights alternative financing mechanisms including fossil fuel taxation and debt cancellation for severely climate-affected nations. India, as both a developing economy and a growing clean energy market, has a direct stake in COP28 finance architecture outcomes, as domestic transition investment requirements climb toward the billions annually.
