GEIA's Mission -- Quantification of chemical emissions into the air is a key step in explaining observed variability and trends in atmospheric composition and in attributing these observed changes to their causes on local to global scales. Accurate emissions data are necessary to identify feasible controls that reduce adverse impacts associated with air quality and climate, to track the success of implemented policies, and to estimate future impacts. GEIA is a community effort that builds bridges between environmental science and policy, by bringing together people, data, and tools to create and communicate the highest quality information about emissions. GEIA seeks to enhance access to emissions data, facilitate analysis to improve the scientific basis for emissions information, and strengthen the emissions community.

GEIA Scientific Steering Committee (SSC), guided by the SSC Mandate, manages GEIA.

GEIA History from 1990 - Present provides details about GEIA's evolution including past leadership, objectives, conferences and other activities and accomplishments.
