The E-waste Statistics: Guidelines on classifications, reporting and indicators, third edition and accompanying statistical annex tables. The tables includes: UNU-KEY-v.2 product descriptions; Concordance tables linking the UNU-KEYs across versions (v.1 - v.2); Concordance tables linking the UNU-KEYs to related international classifications (EU Waste CAT 6PV/10, HS22 and CPC2.1); Product lifetime distribution parameters per UNU-KEY; Per-unit average weights per UNU-KEY; and Material composition data per EU6-PV. Together, these provide the guidance and underlying technical inputs recommended for the consistent and harmonised calculation, compilation, and interpretation of e-waste statistics.
