过去、现在和未来的大气化学、空气质量和气候条件的模拟评估需要在适当的空间和时间尺度上建立适当化学物质的排放清单作为投入。国际全球大气化学项目（IGAC）的全球排放清单活动（GEIA）的任务是编制适合一系列研究应用的全球清单。目前的GEIA项目通常基于按物种解决排放问题；一个由感兴趣的参与者组成的国际工作组合作进行汇编每一份清单所需的工作。介绍了GEIA方案在编制全球挥发性有机化合物（VOCs）人为排放清单方面的工作，该清单以1{度}分辨率网格化。过去的研究是根据人类活动对全球挥发性有机化合物排放的贡献来确定人类活动的，根据这些初步研究的结果，选择了用于排放报告的活动和物种分组。讨论了委员会工作的现状。目前正在编制关于每个确定部门的现有活动率、排放因子和物种形态概况的详细资料。建立了与从事区域一级挥发性有机化合物排放汇编工作的调查人员的联系。
Modeling assessments of the atmospheric chemistry, air quality and climatic conditions of the past, present and future require as input inventories of emissions of the appropriate chemical species constructed on appropriate spatial and temporal scales. The task of the Global Emissions Inventories Activity (GEIA) of the International Global Atmospheric Chemistry Project (IGAC) is the production of global inventories suitable for a range of research applications. Current GEIA programs are generally based on addressing emissions by species; an international working group of interested participants cooperates in the work needed to compile each inventory. The work of the GEIA program addressing the compilation of a global inventory of anthropogenic emissions of Volatile Organic Compounds (VOCs) gridded with 1{degree} resolution is presented. Past studies were used to identify anthropogenic activities according to their contribution to global VOC emissions, based on results of these initial studies, activity and species groupings for emissions reporting have been selected. Current status of the work of the committee is discussed. Detailed information on available activity rates, emission factors, and speciation profiles for each defined sector is being compiled. Links to investigators working on the compilation of VOC emissions on a regional level have been established.
