  1. Calculations are based on (i) the ratio of the uncertainty in emissions from each sector (U_TNOs) to the uncertainty in total emissions (U_TNOTot) and (ii) the relative uncertainty in emissions for Annex I countries (5%) and other countries (10%) from GCB-NAE3.
  2. (a) GCP-GridFED source class codes are adopted from EDGAR. See Table 1 for more information.
  3. (b) 5% uncertainty in total emissions.
  4. (c) 10% uncertainty in total emissions.
