Annual verified emissions and allowance transactions under the EU ETS are provided in the European Transaction Log (EUTL), which is the administrative backbone of the EU ETS. The EUTL, however, only provides greenhouse gas emission data and information on the transfer of emission allowances. This dataset links the EUTL with two other databases, the ENTSOE Transparency Platform and the Industrial Emissions Portal. Power producers are the largest emitters in the EU ETS and linking the EUTL to ENTSOE can provide granular data on their production decisions. Secondly, the EU ETS regulates and reports on specific greenhouse gases such as carbon dioxide or nitrous oxides. The Industrial Emissions Portal (IEP) complements the EUTL by reporting releases of a much broader set of pollutants to air, soil, and water, thereby providing a more nuanced picture of industrial activities in Europe.
