Excite Emulator
Interactive Tools to Explore Climate and Economic Futures
Discover how emissions pathways shape global temperatures and regional economic impacts through scientifically grounded, user-friendly visualisations designed to support informed climate decision-making.
EXCITE (EDHEC Cross-Model Climate Institute Temperature Emulator) is a professionally developed, interactive web-based tool created by the EDHEC Climate Institute. It enables users—including scientists, policymakers, financial professionals, and the broader public—to
explore how global surface temperatures could evolve under a wide range of greenhouse gas emissions scenarios.
EXCITE integrates a comprehensive set of internationally recognised emissions pathways, such as those used by the IPCC (e.g., AR6 and NGFS climate scenarios), and also allows users to construct customised emissions trajectories—either by adjusting emissions parameters directly or by specifying a social cost of carbon. For each selected or user-defined pathway, EXCITE simulates future temperature outcomes using a climate emulator calibrated against leading CMIP5 and CMIP6 models, with configurable filters for "hot", "core", and "cold" model groups.
By combining accessibility with scientific rigour, EXCITE enhances our ability to understand how today’s emissions and policy choices may shape the climate of tomorrow—supporting informed decision-making across research, regulation, and investment.
