Emissions of CO2 - from Transport Road (Model Estimations, RIVM-MNP)

A global emissions source database called EDGAR has been developed jointly by TNO and RIVM to meet the urgent need of atmospheric chemistry and climate modellers and the need of policy-makers. The EDGAR database was to estimate the annual emissions of direct and indirect greenhouse gases (CO2, CH4, N2O; CO, NOx, non-methane VOC; SO2), including ozone-depleting compounds (halocarbons) for 1990 on a regional and grid basis. To meet the aim of establishing the global emissions from both anthropogenic and biogenic sources, a complete set of data would be required to estimate the total source strength of the various gases with a 1x1 degree resolution (altitude resolution of 1 km), as agreed upon in the Global Emissions Inventory Activity (GEIA) of the International Atmospheric Chemistry Programme (IGAC) Emissions of co2 from transport road; corresponds to IPCC category 1A3b.

由荷兰应用科学研究组织（TNO）与荷兰国家公共卫生与环境研究所（RIVM）联合开发的全球排放源数据库EDGAR，旨在满足大气化学与气候建模研究者的迫切需求，同时契合政策制定者的实际应用诉求。该数据库可基于区域与网格尺度，估算1990年各类直接与间接温室气体（二氧化碳CO₂、甲烷CH₄、一氧化二氮N₂O；一氧化碳CO、氮氧化物NOₓ、非甲烷挥发性有机化合物VOC、二氧化硫SO₂）及消耗臭氧层物质（卤代烃）的年排放量。为实现摸清人为源与生物源全球排放总量的目标，需依托完整数据集，以1×1经纬度分辨率（垂直分辨率为1千米）估算各类气体的总源强，该标准由国际大气化学计划（International Atmospheric Chemistry Programme，IGAC）下属的全球排放清单活动（Global Emissions Inventory Activity，GEIA）所确立。其中道路运输产生的二氧化碳排放量，对应政府间气候变化专门委员会（Intergovernmental Panel on Climate Change，IPCC）分类中的1A3b类别。
