The bloc’s decision marks a departure from its recent trajectory, during which it funneled €32.3 billion into developing nations in 2025. Officials point to the high cost of managing domestic energy crises, where soaring fuel and gas prices have forced the EU to prioritize direct subsidies and tax cuts for its own refining sectors over international climate aid. Beyond domestic fiscal pressures, a growing frustration permeates Brussels regarding the lack of burden-sharing among other wealthy nations.

This refusal to open the coffers arrives as developing countries adopt an increasingly aggressive stance. A coalition of African nations has formally demanded that climate adaptation finance be tripled at the summit beginning November 9. These governments have issued an ultimatum to Western donors, essentially threatening to stall their transition away from hydrocarbons unless funding targets are met. With the EU unwilling to bridge the gap, the conference is poised for a significant diplomatic clash between donors and recipients over who should bear the cost of global decarbonization.
