Weather, Climate and Energy Tracker, including two databases: i) IEA and CMCC (2026), Weather for Energy Tracker and ii) IEA and OECD (2026), Climate Hazard Exposure Tracker.

Weather for Energy Tracker: The IEA Weather for Energy Tracker is an online platform developed by the International Energy Agency and CMCC Foundation that provides high-resolution weather and climate data for energy analysis. It allows users to explore and download historical and near-real-time weather and climate variables (e.g. temperature, cooling degree days, precipitation, solar radiation) across global, national, and subnational levels. The tool supports energy modelling and analysis by linking weather and climate conditions to energy demand and system performance. Overall, it functions as a data and analytics platform for the energy–weather and climate interface, rather than a dedicated adaptation decision-support tool. Data are available at grid, country and sub-national levels, with a daily and monthly resolution from the year 1979 to the latest available month, and including monthly climatologies and anomalies. The Weather for Energy Tracker includes data for 51 variables at global gridded level and monthly resolution (including monthly climatologies and monthly anomalies); and data for 50 variables at nationally and sub-nationally averaged levels at daily and monthly resolution (including monthly climatologies and monthly anomalies). Climate Hazard Exposure Tracker: The IEA and OECD Climate Hazard Exposure Tracker and associated databases are a new free platform showcasing the impacts of climate-related hazards on people and infrastructures, including agriculture, the energy sector, forests and built-up areas. Data is available at national and subnational levels. The IEA and the OECD have launched the Climate Hazard Exposure Tracker to help analyse the impacts of various climate hazards on the energy sector, and more broadly on agriculture and other economic activities, as well as people’s quality of life. This unique user-friendly tool provides, for the first time, long-time-series national and sub-national indicators on climate hazards for the whole world, merging information from several high-resolution global gridded climate datasets. The indicators facilitate analysis of how populations, cropland, forests and built-up areas in each country are exposed to extreme temperature, precipitation, drought, wildfires, wind threats, river flooding and coastal flooding. The long duration of the series (1979-2023) allows potential effects of climate change to be assessed, highlighting trends in the occurrence of extreme weather events and their impacts on populations and resources across the globe.

Combines fine-grained global weather and climate information with consistently aggregated national and subnational indicators. The Weather for Energy Tracker supports energy-focused analysis, while the Climate Hazard Exposure Tracker broadens the view to populations, agriculture, forests and built-up areas. This makes the platform useful for identifying trends and screening exposure, although more detailed vulnerability and local impact information is needed for a complete risk assessment.

• Global energy-weather and climate analysis by the IEA and CMCC Foundation.
• National and subnational comparison of climate-hazard exposure through the IEA and OECD tracker.
• Analysis of populations, cropland, forests, built-up areas and energy systems.
• Use by authorities, researchers, businesses, consultants, NGOs and citizens.
• The Climate Hazard Exposure Tracker is online and updated; the Weather for Energy map was under revamp as of 28 August 2026.
