Overview

GEIA, a joint IGAC/iLEAPS/AIMES initiative, seeks to build on the success of the past two decades as a forum for the exchange of expertise and information that unites the scientific, regulatory, and operational emissions communities.

GEIA was founded in 1990 with a mission to:

• Quantify anthropogenic emissions and natural exchanges of trace gases and aerosols that drive Earth system changes, and
• Facilitate use of this information by the research, assessment, and policy communities.

GEIA

• Provides access to various global and regional emission inventories in a consistent framework, in collaboration with ECCAD and CIERA
• Organizes workshops, conference sessions and schools that bring together inventory developers and users
• Facilitates emissions data evaluation and assessment
• Prepares state-of-the-science emissions summaries and provides these data to international scientific projects.

In its new phase initiated in 2011, GEIA aims to demonstrate the potential of improving emission inventories by promoting the interoperability of datasets and tools and by making use of near-real-time observations.

Please see our latest poster presentation for more details on the GEIA’s new directions.
