About GEIA

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 2015 Conference - Program and Summary


17th GEIA Conference

Influence of Urbanization on Emissions Worldwide

18-20 November 2015

Tsinghua University, Beijing, China

This 17th GEIA Conference explored the implications of urbanization on the characterization and analysis of anthropogenic and natural emissions and their environmental and societal impacts at local to global scales.  The Conference focused on understanding how recent measurement advancements, developments in emissions process understanding, and progress in interpreting past emissions trends and projecting future emissions are helping to inform critical societal issues, particularly those related to urbanization.
