The consistency issues are to be seen in relation with (i) Internal calculations of the inventory; (ii) Time-series consistency and; (iii) Consistency between the NIR and the CRF. While reviewing the Energy Sector - Fuel combustion part of a Party’s inventory submission, you should consider the following consistency issues.

Internal consistency:

• Are there any inconsistencies across sectors (e.g., emissions double-counted in the Energy and Industrial Processes Sectors or emissions due to electricity autoproduction)?
  
• Are the explanations for the differences between emission estimates for each fuel type using the Reference and Sectoral approaches reasonable?
