UN Carbon Footprint Indicators for Climate Action
Measuring a global carbon footprint is a multi-layered process that requires coordination across nearly every specialized agency within the United Nations. As of 2025, the UN Statistics Division (UNSD), in collaboration with the UNFCCC, has standardized this process through the Global Set of Climate Change Statistics and Indicators. This comprehensive framework of 75 indicators is designed to provide a unified "Carbon Ledger" for the planet, moving beyond simple emission totals to track the economic drivers, industrial sources, and environmental impacts of human activity. By categorizing the footprint into five distinct areas—Drivers, Emissions, Impacts, Mitigation, and Adaptation—these indicators allow agencies like the FAO, UNIDO, and the IEA to monitor everything from methane leaks in agriculture to the carbon intensity of global trade.
