The National Inventory Report 2014 (NIR 2014) gives a detailed and comprehensive description of the methodology applied in the Austrian air emissions inventory for the greenhouse gases of the “Kyoto basket” (carbon dioxide, methane, nitrous oxide, HFC, PFC and SF6). With this report, Austria complies with its reporting obligations under the UNFCCC and the Kyoto Protocol by providing transparent and verifiable documentation. It contains emissions data by sector as well as information on emission factors, activity data and other basic data for emission calculations. By submitting data for the years 1990 to 2012, it serves as the basis for final reporting and accounting under the first commitment period under the Kyoto Protocol. Moreover, the report provides documentation of the national inventory system and quality assurance as performed by the accredited inspection body (ISO/IEC 17020) on emission inventories.
