………….AUSTRALIAN GREENHOUSE EMISSIONS INFORMATION SYSTEM…………

Inventory Management & Archiving

Australian Greenhouse Emissions Information System

(AGEIS)


AGEIS: Development objectives

• Inventory Data Management ……• National & set of 8 state & territory inventories • Raw input data: 6,500 data points per year –

90,000 per submission– Total input data/preliminary calcs: 50,000 per inventory

year - 600,000 per submission– Emissions data - ……..now in the millions– Notation keys……hundreds of thousands

• Problems for data management, and problems for accessibility/usability


AGEIS: Development objectives

• Data management……• Upgrade QC systems• Replace unwieldy excel spreadsheeting• Reduce reliance on sectoral experts• Enhance public access to the data• Documentation systems – for review and for

durability

AGEIS Development

• Significant time, resource and budgetary commitment

• Significant software maintenance commitment

• SQL

AGEIS Data Management Systems: key elements

• Separation of roles & responsibilities; user accounts & privileges

• Standardised templates for input data entry– System documents timing and author of data

inputs


Standardised input data entry


AGEIS Data Management Systems

• Separation of roles & responsibilities and accounts & privileges

• Standardised templates for input data entry• System allocation of data into libraries• Security of core input data

– Outer database workspace for analysts– Transfer to core database by ‘Database Manager’– Copied to external database for public access


AGEIS: Integrated QC systems

• AGEIS now at heart of QA/QC plan• System provides verification tools/tests for

input data & emissions outputs– Records history of QC assessment & provides

for independent assessments


AGEIS: QC systems (Manager)


AGEIS: public access: interactive web interface


AGEIS public access


AGEIS: integrated documentation systems

• Documentation of emissions estimation methodologies– Australian Methodology for the Estimation of Emissions

and Sinks 2002: series ….across 500 pages (2004)• Update each year

– Emissions equations/factors - rationales for selection• AGEIS links emissions data, method

documentation, SQL coding, input data


Source, method documentation & coding


Clinker: coding


Methodology, input data & tier


AGEIS: Integrated documentation systems

• Documentation of emissions estimation methodologies– Recreations feasible– Methodology for any year may be combined

with past input datasets– Necessary for system maintenance

• Documentation of metadata for data inputs


Archiving / storage

• Estimation methodologies / equations…• Input datasets• Emission estimate datasets for three

submissions at any time– emissions estimates can be recreated at any time

• Empirical research library (ongoing)• Past NIRs, CRF Tables etc


Next steps

• Development of broader national emission accounts

• Linkages with AGO programmes• Development of analytical tools• Integrated uncertainty analysis
