The scientific capabilities of today's atmospheric observing and modeling systems, combined with better quantification of the controlling processes of different sources, are contributing to a transformation in how we account for and understand emissions of greenhouse gases and air pollutants. This shift is providing new approaches to derive, verify, and forecast emissions and to quantify their impacts on the environment.

GEIA's work to facilitate emissions analysis includes initiating active discussions about forefront emission challenges and contributing to a wide variety of projects aimed at increasing emissions understanding around the world.

GEIA members work together in Working Groups focused on key emission issues, on Overarching Activities, and through collaborations with other science and policy related groups.

GEIA members frequently publish new results which help continue to advance understanding.
