Anthropogenic emissions of carbon dioxide (CO), methane (CH) and nitrous oxide (NO) have made significant contributions to global warming since the pre-industrial period and are therefore targeted in international climate policy. There is substantial interest in tracking and apportioning national contributions to climate change and informing equitable commitments to decarbonisation. Here, we introduce a new dataset of national contributions to global warming caused by historical emissions of carbon dioxide, methane, and nitrous oxide during the years 1851-2021, which are consistent with the latest findings of the IPCC. We calculate the global mean surface temperature response to historical emissions of the three gases, including recent refinements which account for the short atmospheric lifetime of CH. We report national contributions to global warming resulting from emissions of each gas, including a disaggregation to fossil and land use sectors. This dataset will be updated annually as national emissions datasets are updated.
自工业化前时期以来，人为排放的二氧化碳（CO）、甲烷（CH）和氧化亚氮（NO）对全球变暖做出了重大贡献，因此成为国际气候政策的目标。人们非常关注跟踪和分配各国对气候变化的贡献，并为脱碳做出公平的承诺。在这里，我们引入了一个新的数据集，其中包含了 1851 年至 2021 年期间二氧化碳、甲烷和氧化亚氮历史排放对全球变暖的国家贡献，这些数据与 IPCC 的最新发现一致。我们计算了全球平均地表温度对这三种气体历史排放的响应，包括最近对 CH 短大气寿命的修正。我们报告了每种气体排放对全球变暖的贡献，包括对化石燃料和土地利用部门的细分。随着国家排放数据集的更新，该数据集将每年更新。
