The CEDS Sankey Visualization Tool leverages data from the Community Emissions Data System (CEDS), a comprehensive open-source framework for historical emission estimates. This allows users to explore emission trends, as CEDS provides consistent data for global air emissions species (BC, CO, CO2, NH3, NMVOC, NOx, OC, SO2) over the industrial era (1750 – present) along with CH4 and N2O over recent decades. With the Sankey tool, users can easily visualize emission flows across sectors and how different sectors contribute to global emissions, as well as track the impact of technologies on global emissions, ultimately gaining data-driven insights to support informed decision-making for a sustainable future.
