The Global Emissions Inventory Activity (GEIA)

International audienceThe objective of the GEIA project is to bring together people, analyses, data, and tools to quantify the anthropogenic emissions and natural exchanges of trace gases and aerosols that drive Earth system changes and to facilitate the use of this information by the research, assessment and policy communities. The presentation will provide an overview of the current activities of GEIA. We will present the GEIA network, which currently includes over 1000 people around the globe, and the plans to extend this network to different communities working on environmental changes issues. We will also present our plans to develop within the GEIA Center (www.geiacenter.org) a new database of scientific papers as well as national and international reports dealing with emissions issues. We will also present the main conclusion of the GEIA conference, which took place in October 2009. Given the differences often found among data sets, we will discuss the formation of a GEIA working group composed of emission developers and modelers who will compare data sets and implications for modeling. It has been recognized that consistent information on emissions at the global and regional scale is required, as well as an accurate quantification of emissions in the different megacities of the world. In order to develop these perspectives, GEIA will begin strengthening links with different key regions: we will discuss the plans for developing regional centers through corporation with other entities and individuals working in these regions
