  2. 2. IETA MRG Work Group <ul><li>One of a number of IETA WGs looking at Phase II issues </li></ul><ul><li>Representatives from Industry Sectors and Verifiers </li></ul><ul><li>Desire to cooperate with Commission and Ecofys in producing a user-friendly Phase II MRG. </li></ul>
  3. 3. Cross-cutting issues: Ambiguity <ul><li>Consistency in application across Member States is important </li></ul><ul><li>Need to review and incorporate the Commission's Q&As </li></ul><ul><li>Recommend that the Q&As be kept live to promote consistent application across Member States </li></ul>
  4. 4. Cross-cutting issues: ISO 17025 <ul><li>Limited number of accredited labs </li></ul><ul><li>Use of equivalent “standards” </li></ul><ul><li>Problem of dropping a Tier </li></ul><ul><ul><li>Use of default emission factors </li></ul></ul><ul><ul><li>Introduces a known bias </li></ul></ul><ul><ul><li>Conflict with principle of accuracy </li></ul></ul>
  5. 5. Cross-cutting issues: Role of overall uncertainty <ul><li>Overall uncertainty analysis </li></ul><ul><ul><li>Required or not? </li></ul></ul><ul><ul><li>Ambiguous </li></ul></ul><ul><li>Purpose of Table 3 </li></ul><ul><li>Could be used to select the appropriate Tier for activity data based on the contribution of that source to the overall uncertainty. </li></ul>
