Comparing the Global Warming Impacts of Ireland and EU27

This repository provides the data needed to compare the relative global warming impact of the EU27 and Ireland in respective climate-neutral scenarios for these jurisdictions. The datasets eu_nzero_emissions_1850_2100 and eu_warming_nzero_ssp126_1850_2100 contain emissions and calculated warming impact in the EU27 climate neutral "NZero" scenario as defined by the European Advisory Board on Climate Change. The datasets ie_emissions_2050_300mt_l4_s2p2 and ie_warming_300mt_l4_s2p2_ssp126_1850_2100 contain emissions and warming impact of the IE scenario 300mt L4 S2_P2 as defined by Ireland's Climate Change Advisory Council (CCAC). Warming impacts are calculated in a constrained ensemble of FaIR2.2 model configurations, using a background SSP1-26 global emissions pathway and the standard "leave-one-out" method. The climate drivers used are CO2, CH4, N2O and SO2. Other short-lived pollutants and F-gases are omitted from the warming impact calculations. The dataset ie_emissions_2050_300mt_l4_s2p2 shows the projected IE 2050 emissions broken down by gas and sector for the 300mt L4 S2_P2 scenario. This was the most ambitious scenario considered feasible by CCAC. This scenario is temperature-neutral in ~2040, but still has significant CO2-equivalent agricultural gas emissions in 2050.本仓库提供了用于比较欧盟27国（EU27）与爱尔兰在各自气候中和场景下相对全球变暖影响所需的全部数据。 数据集eu_nzero_emissions_1850_2100与eu_warming_nzero_ssp126_1850_2100包含欧盟27国依据欧洲气候咨询委员会（European Advisory Board on Climate Change）定义的气候中立"NZero"场景中的排放量与测算得到的变暖影响。 数据集ie_emissions_2050_300mt_l4_s2p2与ie_warming_300mt_l4_s2p2_ssp126_1850_2100则包含爱尔兰气候咨询委员会（Climate Change Advisory Council, CCAC）定义的IE场景300mt L4 S2_P2的排放量与变暖影响。 变暖影响通过受约束的FaIR2.2模型集合配置进行测算，采用背景SSP1-26全球排放路径与标准"留一法（leave-one-out）"方法。所用气候驱动因子包括二氧化碳（CO₂）、甲烷（CH₄）、一氧化二氮（N₂O）与二氧化硫（SO₂），其他短寿命污染物及氟化气体（F-gases）未纳入变暖影响测算范围。 数据集ie_emissions_2050_300mt_l4_s2p2展示了300mt L4 S2_P2场景下爱尔兰2050年预计排放量按气体种类与行业门类的细分情况。该场景是CCAC认定的最具可行性的高雄心度场景，可在约2040年实现温度中性，但在2050年仍存在显著的二氧化碳当量农业气体排放。
