A new research project aims to improve the effectiveness of countries' plans to reduce greenhouse gas emissions, known as Nationally Determined Contributions (NDCs). Currently, many NDCs lack clear targets and indicators, making it difficult for countries to track their progress. To address this issue, researchers propose a framework that encourages experts in climate modeling to use open-source tools and share data openly. This approach is being tested in Costa Rica, with the goal of promoting more transparent and accountable climate action plans that can help countries meet their global emissions reduction targets.
