I propose to take Questions Nos. 243 to 246, inclusive, together.
The European Commission publishes an annual list of aircraft operators attributed to each EU Member State. The list for 2019 can be found here: https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32019R0226&from=EN
The European Commission also publishes a “Verified Emissions” report each year which details the aircraft operators registered in each Member State that fall and do not fall under the ETS. These annual "Verified Emissions" reports are listed at https://ec.europa.eu/clima/policies/ets/registry_en#tab-0-1. All aircraft operators are listed under the activity code “10”. Operators that are marked as “excluded” are not included under the ETS. The latest report gives annual CO2 emissions for each aircraft operator for the years 2012-2018. Aviation data for individual operators is available for 2012-2018 only.
All fuel used and associated emissions by aircraft (non-military) departing from an Irish aerodrome and arriving at the same or another Irish aerodrome are reported in Ireland’s GHG inventories under Domestic Aviation. All other fuel sold, and the associated emissions for international aviation, are reported in Ireland’s GHG inventory under "Memo items" and are not included in national totals under the UNFCCC or the EU Effort Sharing Decision commitments.
