Résumé : Available data show that Vietnam emerges as one of the first recipients of climate changeadaptation-related aid. In addition, reporting by OECD Development Assistance Committee (DAC)members based on the Rio marker methodology indicates that Vietnam attracted a significantly largestshare of “international adaptation finance” than of bilateral official development aid (ODA) while thiscountry is at the same time one of the first recipients of bilateral ODA in the world (third biggestrecipient in 2010-2013).Our screening of aid activities labelled by DAC donors as adaptation-related in Vietnam shows thatthese observations need to be qualified. The case of Vietnam illustrates some of the practicalchallenges of monitoring international climate finance and some of the weaknesses of currentreporting systems in this regard. Any estimates of international climate finance should therefore beconsidered with caution.This paper also highlights the limits of a strictly accounting approach to international climatefinance – an approach that is however particularly apparent in negotiations under the United NationsFramework Convention on Climate Change (UNFCCC). This approach could indeed provide adisincentive to use some types of aid (such as general budget support or debt relief) that are potentiallyhighly relevant to address intersectoral issues such as climate change adaptation and mitigation.
