Accurate, timely, and accessible emissions information is critical for understanding and making predictions about the atmosphere. We present an overview of the Global Emissions InitiAtive (GEIA, http://www.geiacenter.org/), a community-driven, joint activity of the International Global Atmospheric Chemistry/integrated Land Ecosystem-Atmosphere Process Study/Analysis, Integration and Modeling of the Earth System within the International Geosphere-Biosphere Programme. Since 1990, GEIA has served as a forum for the exchange of expertise and information on anthropogenic and natural emissions of trace gases and aerosols. GEIA supports a worldwide network of about 1300 emissions data developers and users, providing a solid scientific foundation for atmospheric chemistry research. Moving forward, GEIA seeks to build bridges between the environmental science, regulatory, policy, and operational communities. GEIA’s core activities include: 1) facilitating analysis that improves the scientific basis for emissions data, 2) enhancing access to emissions information, and 3) strengthening linkages within the international emissions community. GEIA pursues these activities in collaboration with the Emissions of Atmospheric Compounds and Compilation of Ancillary Date (ECCAD) Project (http://pole-ether.fr/eccad) and as a member of the Group on Earth Observations Air Quality Community of Practice (http://wiki.esipfed.org/index.php/GEO_AQ_CoP). GEIA welcomes new partnerships that advance emissions knowledge for the future.
