 This paper presents a new data set of national contributions to global warming caused by historical emissions of carbon dioxide, methane, and nitrous oxide between 1851 and 2021. The data is based on the latest findings of the Intergovernmental Panel on Climate Change, IPCC. It includes a breakdown of the contribution of each gas to global warming, as well as a desegregated analysis of the impacts of emissions from different sources such as fossil fuels and land use. The authors also provide an annual update of the data set, making it easier to track changes in national contributions over time. This article was authored by Matthew W. Jones, Glenn P. Peters, Thomas Gasser, and others.
