Activity data

Activity data are taken from consumption data given in official Energy Balances for Germany (AGEB, 2011) [1].

Table: Sources for consumption data in 1.A.4.b ii

Relevant years Data Source
through 1994 AGEB - National Energy Balance, line 79: Households
since 1995 AGEB - National Energy Balance, line 66: Households

Within the Energy Balances the quality of the activity data provided for households is only poor due to missing statistical data on combustion engine mobile machinery used in German households.

Trend discussion for Key Sources

NFR 1.A.4.b.ii - Mobile Sources in Household and Gardening is no key source.

Recalculations

AD: All emissions reported for 2009 had to be recalculated due to a revised 2009 Energy Balance.

For information on the impacts on 1990 and 2009 emission estimates, please see the pollutant specific recalculation tables following chapter 11.1 - Recalculations.

Uncertainties

Uncertainty estimates for activity data of mobile sources derive from research project FKZ 360 16 023: "Ermittlung der Unsicherheiten der mit den Modellen TREMOD und TREMOD-MM berechneten Luftschadstoffemissionen des landgebundenen Verkehrs in Deutschland". For detailled information, please refer to the project's final report here (German version only!).

Uncertainty estimates for emission factors were compiled during the PAREST research project. Here, the final report has not yet been published.

Planned improvements

At the moment, no category specific improvements are planned.
