OECD’s latest report confirms that developed nations surpassed the long-elusive USD 100 billion annual climate finance goal in 2022, 2023 and 2024. Yet beneath this headline figure lies a more fractured reality: one of structural imbalances, instrument distortions, and distributional inequities that complicate the narrative of progress.

Mitigation Finance: Volume Without Breadth

• Mitigation finance dominates, commanding nearly two-thirds of total climate flows, peaking at USD 87.3 billion in 2023.
• However, sectoral concentration is stark: the energy sector alone absorbed 41% of mitigation finance over 2016-2024.
• Delivery is predominantly loan-based, favouring middle-income countries where private capital can be more readily mobilised, leaving other critical sectors underleveraged.

Adaptation Finance: A Structurally Neglected Pillar

• Adaptation's thematic share has eroded from 34% in 2020 to just 25% in 2024, despite modest absolute growth.
• Meeting the 2021 Glasgow Climate Pact's doubling commitment requires substantial additional funding.
• With over 90% of adaptation finance sourced from public channels, private mobilisation has effectively stalled.

Summing Up

COP30 called for efforts to at least triple adaptation finance by 2035 in the context of the New Collective Quantified Goal on Climate Finance. Against this backdrop, correcting adaptation underfunding and reducing debt-instrument dependency – particularly for the most vulnerable nations – must define the next financing architecture.
