NAVIGATE aims to develop the Next generation of AdVanced InteGrated Assessment modelling to support climaTE policy making.
NAVIGATE will critically improve the capability of Integrated Assessment Models (IAMs) to inform the design and evaluation of climate policies by targeting major advancements in two areas: describing transformative change in the economy, in technology and in consumer goods and services, and describing distributional impacts of climate change and climate policy. By tackling existing weaknesses and lack of capabilities of the current generation of IAMs, NAVIGATE will provide new insight into how long-term climate goals can translate into short-term policy action, and how countries and sectors can work in concert to implement the Paris Agreement.
IIASA leads the work on energy demand in the NAVIGATE project and works on improving the representation of energy demand modeling for the buildings and transport sectors in the MESSAGEix-GLOBIOM framework. We also work to improve the modeling frameworks for energy-water-land nexus research and the tools to explore synergies and trade-offs between mitigation and the Sustainable Development Goals.
