Short description
Under sub-category 1.A.4.b ii - Residential: Mobile Sources in Households and Gardening fuel combustion activities and resulting emissions from combustion engine driven devices such as motor saws and lawn mowers are being reported.
| NFR-Code | Source category | Method | AD | EF | Key Source for (by 1) |

Method
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.

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.
