Division 1 A Member State that proposes an adjustment to its national emission inventory in accordance with Article 5(1) shall include in its proposal to the Commission, at least, the following supporting documentation:

evidence that the concerned national emission reduction commitment/s is/are exceeded;

evidence of the extent to which the adjustment to the emission inventory reduces the exceedance and contributes to compliance with the concerned national emission reduction commitment/s;

an estimation of whether and when the concerned national emission reduction commitment/s is/are expected to be attained based on national emission projections without the adjustment;

evidence that the adjustment is consistent with one or several of the following three circumstances. Reference can be made, as appropriate, to relevant previous adjustments:

1. (i)

   in the case of new emission source categories:

   • evidence that the new emission source category is acknowledged in scientific literature and/or the EMEP/EEA Guidebook;

   • evidence that this source category was not included in the relevant historic national emission inventory at the time when the emission reduction commitment was set;

   • evidence that emissions from a new source category contribute to a Member State being unable to meet its emission reduction commitments, supported by a detailed description of the methodology, data and emission factors used to arrive at that conclusion;

2. (ii)

   in the case of significantly different emission factors used for determining emissions from specific source categories:

   • a description of the original emission factors, including a detailed description of the scientific basis upon which the emission factor was derived;

   • evidence that the original emission factors were used for determining the emission reductions at the time when they were set;

   • a description of the updated emission factors, including detailed information on the scientific basis upon which the emission factor was derived;

   • a comparison of emission estimates made using the original and the updated emission factors, demonstrating that the change in emission factors contributes to a Member State being unable to meet its reduction commitments;

   • the rationale for deciding whether the changes in emission factors are significant;

3. (iii)

   in the case of significantly different methodologies used for determining emissions from specific source categories:

   • a description of the original methodology used, including detailed information on the scientific basis upon which the emission factor was derived;

   • evidence that the original methodology was used for determining the emission reductions at the time when they were set;

   • a description of the updated methodology used, including a detailed description of the scientific basis or reference upon which it has been derived;

   • a comparison of emission estimates made using the original and updated methodologies demonstrating that the change in methodology contributes to a Member State being unable to meet its reduction commitment;

   • the rationale for deciding whether the change in methodology is significant.
