Cross-validation of waste statistics data Comparison with other reporting obligations Cross-validation of waste statistics data THE CONTRACTOR IS ACTING UNDER A FRAMEWORK CONTRACT CONCLUDED WITH THE COMMISSION

Overview Introduction Example: Generation of WEEE & ELV Example: PRTR Example: Generation of C&D-Waste (WFD)

Why to carry out cross-validation? Some other reporting obligations are partly overlapping with the obligations of the WStatR EU waste data from different sources should ideally be coherent / free of contradictions Cross-checking  mutual improvement of the data quality Explanations of inconsistencies (e.g. in the Quality Report) ease the validation, cross-country comparison and interpretation of waste statistics

Reporting obligations of special relevance for cross-validation Waste Electrical and Electronic Equipment (WEEE) End of life vehicles (ELV) Waste Shipment Packaging and packaging waste Waste Framework Directive - Recycling/recovery targets PRTR

Challenges related to cross-validation Differences in coverage and definitions Reporting responsibilities are shared with different administrative bodies The same reporting deadlines (end of June)  Data for some other reporting obligations is produced simultaneously with waste statistics

The approach in Austria Umweltbundesamt gathers all reports related to waste, including method descriptions Cooperation / discussions with other administrative bodies responsible for waste reporting For each waste statistics report, cross-validation is carried out covering all waste related reporting obligations.  Results are documented in a special quality report

Example: Generation of WEEE & ELV

Cross-check with WEEE-reporting: Comparability The total generation of the category “discarded equipment” (WStatR) can be compared with the collected amounts of WEEE (WEEE-Dir) Differences in the coverage: EWC-Stat category 08 Discarded equipment covers all LoW-codes that refer to WEEE with the exception of PCB-containing equipment and equipment containing free asbestos. In addition to the WEEE-related waste types, the category discarded equipment includes wastes / components from the dismantling of end-of-life vehicles. WStatR-data may include double-counted amounts due to pre-treatment steps

Cross-check with WEEE-reporting: Validation rule Validation rule: Discarded equipment generated (WStatR) > Discarded equipment collected (WEEE-Dir) Example: Austrian data Reference year Discarded equipment generated (WStatR) Discarded equipment collected (WEEE-Dir) 2012 82.419 77.402 2014 85.106 77.726

Cross-check with WEEE-reporting: WStatR and WEEE-Dir in 2014

Cross-check with ELV-data: Comparability The total generation of the category “discarded vehicles” (WStatR) can be compared with the total weight of end-of life vehicles (ELV- Dir). Differences in the coverage: End-of-life vehicles are covered by category EWC-Stat 08.1 Discarded vehicles. Covers end-of-life vehicles as defined by ELV-Directive (passenger cars, small trucks, ..) but also any other vehicles like heavy trucks and off-road machinery WStatR-data may include double-counted amounts due to pre-treatment steps Parts of ELV and materials from the treatment of ELV are reported either under the category EWC-Stat 08 Discarded equipment or under the respective materials

Cross-check with ELV-data: Validation rule Validation rule: Discarded vehicles generated (WStatR) > Total weight of end-of-life vehicles (ELV-Dir) Example: Austrian data

Cross-check with ELV-data: WStatR and ELV-Dir in 2014

Example: PRTR

Reporting on waste to the E-PRTR Facilities included in Annex I of Regulation 166/2006/EC 65 E-PRTR economic activities Total quantities of hazardous and non-hazardous waste per year Off-site transfers of more than 2000 tonnes non hazardous Off-site transfers of more than 2 tonnes hazardous waste The amounts are to be related to recovery and disposal Transboundary shipments of hazardous waste Off-site of more than 2 tonnes hazardous waste per year details of the waste receivers have to be provided.

Comparability of the E-PRTR data with Waste Statistics Total quantities of hazardous waste and of non-hazardous waste can be compared on the level of economic categories of Annex I of the WStatR Because of the reporting thresholds and because E-PRTR does not cover internal treatment, the E-PRTR data does not have full coverage  the E-PRTR quantities should generally be lower than the quantities reported under WStatR

Example: Generation of C&D-Waste (WFD)

Compliance Reporting on WFD: Recovery rate of C&D Waste The recovery rate is defined as follows: Calculation methods: Materially recovered amount: Calculation on basis of national data WStatR data do not allow determining the recovery of C&D waste accurately, e.g. due to the impact of imports and export Generated amount of C&D waste: 1) Use of WStatR data (details are defined in 2011/753/EC) or 2) Use of national data

Cross-check of generated quantities of C&D-waste 2012 Source: Eurostat 2016, Doc. WASTE WG 4.5(2016), Item 4.5 on the agenda, Working Group on waste statistics 1 and 2 March 2016

Some results of the cross-validation Significant differences (> 20%) between WFD and WStatR data on generated quantities occurred in 12 of the 25 reporting countries Reasons include: Different data sources Data compilation by LoW-codes, in combination with excessive use of codes for metal wastes Incorrect data coverage Submission of provisional data Different reference years Source: Eurostat 2016, Doc.
