Austrian Air Emission Inventory (1)

Umweltbundesamt designated as single national entity responsible for inventory preparation (Environmental Control Act).

International reporting obligationso UNFCCC + EU (Kyoto, MM): Direct and indirect GHGo UNECE(CLRTAP) + EU (NEC): SO2, NOX, NMVOC, NH3, Heavy

metals and POPs Reporting format

o Harmonized formats (CRF, NFR) and methodologies (IPCC, CORINAIR)

o Reporting of „activity data“ (e.g fuel consumption) Quality management system according to ISO 17020

(accreditation 2005)

Austrian Air Emission Inventory (3)

Quality requirementso Accuracyo Consistencyo Transparencyo Completenesso Comparability

STATISTIK AUSTRIA is the most important data provider o Energy balance: covers 75% of GHG emissionso Agricultural data: covers 5% of GHG emissions

Data must be delivered on time to meet the reporting deadlines

Cooperation with STATISTIK AUSTRIA (1)

Informal cooperation between Umweltbundesamt and STATISTIK AUSTRIA since 2000

Joint study „Energy Data Harmonisation for CO2 Emissions Calculations” in 2002 (EUROSTAT)

QMS-Audit of data provider STATISTIK AUSTRIA (2007) Established working process - legal basis:

o Federal Statistics Act regulates the establishment of energy balance: not detailed enough

o Five year framework contract between Energy and Environment Ministry and STATISTIK AUSTRIA

Umweltbundesamt is invited to participate in planning and analysis of existing and new surveys.

o Environmental Control Act: specifies exchange of information between Umweltbundesamt and STATISTIK AUSTRIA

Cooperation with STATISTIK AUSTRIA (2)

STATISTIK AUSTRIA yearly submits to Umweltbundesamt:o National Energy Balance + 9 Regional energy balanceso IEA-JQ (End of November, Eurostat)o Time series (JQ-compatible) (same data but different format)o Additional information (e.g. time series of transformation input by

sector by detailed energy carrier) Umweltbundesamt yearly submits to STATISTIK AUSTRIA

o EU-ETS data (fuel consumption, NCV, share of biomass) (200 plants ≈ 30 Mio t CO2 )

Standardized exchange data formats (spreadsheets) Standardized fuel definitions (both direction) Umweltbundesamt validates energy balance data with other

information i.p.:o Large plant data (LCP, EU ETS). o Waste statistics: Waste incineration, industrial waste (share of

biomass, type of waste).

-> Feedback to STATISTIK AUSTRIA

19.04.23| Folie 9

Harmonisation/improvements Road Transport/off-road: Sectoral fuel consumption of

GLOBEMI transport model was different from energy balance i.p for industry and agriculture.o Harmonized approach is used: quality of off-road transport data

improved Aviation: National vs. international. Different

approaches were used.o Harmonized approach is used: Umweltbundesamt provides data to

STATISTIK AUSTRIA based on flight control data Non-energy use: Double counting with process

emissions -> Energy balance is not a carbon/material balance.

Consumption of biomass heatings (non-traded fuels; small district heatings): high uncertainty; Key source for non-GHG.
