A transparency framework has been enhanced under the Paris Agreement. Developing countries need to develop the capacity to regularly update national greenhouse gas (GHG) inventories, thereby tracking progress toward climate change mitigation goals under their nationally determined contributions (NDCs). Although much study in recent years has been focused on the challenges faced by developing countries in building the long-term institutional capabilities required for more frequent inventory reporting, little work has been done to analyze the institutional linkage between the national GHG inventories and NDCs in the respective countries. Against this backdrop, we examined the cases of Vietnam and the Philippines. Through desktop reviews and a series of interviews conducted in 2018, the present study characterized their institutional designs for the national GHG inventory. It also evaluated observed outcomes of institutional performance in the following dimensions: (1) the frequency and quality of national GHG inventory reporting and (2) the effectiveness of the national GHG inventory at informing the process to formulate mitigation actions under NDCs. The study found that there are differences in performance outcomes between the two countries, which may be linked to the differences in institutional designs. It also found potential trade-offs: A good performance outcome in one dimension may not necessarily translate into a similar result in the other. The findings have implications for transparency-related capacity building assistance: A sound understanding of institutional arrangements and their potential consequences is important for development partners to facilitate the interplay between the national GHG inventory and NDCs in developing countries.
