Regarding the distribution of energy consumption for industrial sources
(CRF sector 1A2), a more detailed and frequently updated data material
would be preferred. There is ongoing work to increase the accuracy and
completeness of this IPCC source category. It is not assessed that this has
any influence on the overall emission level of greenhouse gases.

There is no missing accessibility to critical data sources.

A change in calculation procedure would entail that an updated description
would be elaborated.

During data processing it is checked that calculations are done correctly.
This is to a wide degree documented in the data processing spreadsheets.

Time-series for activity data on SNAP level and sectoral level (see main report)
are used to identify possible errors in the calculation procedure. Timeseries
for emission factors and fuel consumption are also scrutinized.

The IPCC reference approach validates the fuel consumption rates and CO2
emissions of fuel combustion. Fuel consumption rates and CO2 emissions
differ by less than 2.0 % (1990-2009). The reference approach is further discussed
in the main report.

There is a direct line between the external datasets, the calculation process
and the input data used to Data Storage level 2. During the calculation process
numerous controls are conducted to ensure correctness, e.g. sum checks
of the various stages in the calculation procedure.
