Presentation Transcript

  1. Development of Country by Country Emission Data for HFCs: HFC-134a

  2. Development of Country by Country Emission Data for HFCs: HFC-134a • Sources of Information: • AFEAS - global total, hemispherical distribution • European Union - data submitted by • manufacturers to CEC • National data reported to UNFCCC • as required by Rio Convention • published in the Common Reporting Format

  3. National data reported to UNFCCC Sales = domestic production + imports - exports Emissions = summation of expected losses from the population of equipment and systems ("Bottom - up": such calculations invariably understate emissions)

  4. Measured HFC-134a concentrations as reported on CDIAC

  5. AFEAS Differences are likely due to model

  6. Original (CRF) UNFCCC data Differences are result of understated emissions

  7. UNFCCC data revised - recalculated from Sales reported by UNFCCC
