Last updated on 18 Mar 2020 09:41 (cf. Authors)

Short description

Within NFR 5.E.2 - Other Waste: Building and Car Fires, emissions from building and car fires are reported.

NFR Code Name of Category Method AD EF Key Category 1
5.E.2 Other Waste: Building and Car Fires D NS D L & T: PM2.5, PCDD/F

Method

With a new method developed within a research project [2] a country-specific method is implemented. So now it is possible to estimate a full-scale-approach for all Buildings and the cars, additionally an estimation of waste container figure.
In all cases only accidental fires are mentioned (including acts of vandalism).

Activity data

Official population statistics for Germany are applied as primary activity data.
From these statistical input data, the number of fires is estimated via the following steps:

  • specific values for number of fires per 1,000 inhabitants, differentiated according to building, vehicle and container fires
  • Determination of the number of relevant fires per year in Germany in total
  • Differentiation of the fires according to building and vehicle fires
  • Differentiation of fires according to fire scale
  • Differentiation of building fires by building category
  • Conversion of different fires per year to full-scale fires per year
  • Transfer of the results on the number of fires in the form of number of full-scale fires per year differentiated by fire categories

In order to apply the emission factors available from the EMEP/EEA Guidebook, the annual number of building fires is differentiated for detached and undetached, appartment and industrial buildings:

Table 1: Estimated shares per building category, for 2018
detached houses undetached houses appartement buildings industrial buildings
53% 13% 13% 20%
Table 2: Estimated number of full-scale fires, per category, per 1,000 inhabitants, for 2018
detached houses undetached houses appartement buildings industrial buildings cars/ vehicles containers
0.02 0.05 0.05 0.08 0.18 0.15

Emission factors

For most of pollutants Tier2 default values from the EMEP/EEA air pollutant emission inventory guidebook 2019 (as 2016), Chapter 5.E - Other waste, tables 3-2 to 3-6 are applied [1]. Due to gap for emissions factors of black carbon we assume the following analogy: 10% of PM2.5 from Table 3-40, Tier 2 emission factor for conventional stoves, wood and similar wood waste. Regarding containers we use figure of Table 6.22 of Danish IIR (http://cdr.eionet.europa.eu/dk/un/clrtap/iir/envxgkjdw/Denmarks_Informative_Inventory_Report_2019.pdf)

In contrast to building fires, in accordance to the emission factor values provided in the EMEP/EEA Guidebook, no additional differentiation e.g. of vehicle categories is implemented.

Verification

For verification purposes, a consultant has checked the Informative Inventory Reports (IIRs) of other countries. In the IIRs of Denmark and Iceland it is additionally stated that the emission factors refer to so-called "full-scale fires" and therefore the activity data (i.e. the number of fires) must be converted to so-called full-scale equivalent fires.

Recalculations

Recalculations were necessary due to revised method regarding AD resulting in lower emissions amounts regarding all years.

For more information on recalculated emission estimates for Base Year and 2017, please see the pollutant-specific recalculation tables following chapter 8.1 - Recalculations.

Planned improvements

No activities at the moment.
