2.L(b) - Diffuse Emissions from Industrial Establishments

Last updated on 16 Oct 2015 06:20 (cf. Authors)

Short description

NFR category 2.L(b) - Diffuse Emissions from Industrial Establishments includes also diffuse emissions from enterprises in general kind.


As no detailed data are available and as NFR 2.L(b) is no key category, all emissions are calculated via a tier1 method.
Estimations are based on an European method computing emissions per person of population.

Actvity data

Table 1: number of inhabitants in Germany
1990 1995 2000 2005 2006 2007 2008 2009 2010 2011 2012 2013
inhabitants 79,753,000 81,817,000 82,260,000 82,438,000 82,315,000 82,218,000 82,002,000 81,802,000 81,752,000 80,328,000 80,524,000 80,524,000

Emission factors

Emission factors originate in the results of a research project with respect to the European RAINS model. - The EF time series for all three fractions of particulate matter show a falling trend.

Pollutant EF
TSP 0.3052
PM10 0.1008
PM2.5 0.0336

Discussion of emission trends

The diffuse particulate matter emissions reported here, depend on (a) the number of inhabitants in Germany, serving as activity data, and (b) on the trend in emission factors that shall reflect the efforts to prevent such particle emissions. Hence, the emission time-series for all three fractions of particulate matter show a downward trend.


As activity data (number of inhabitants) and emission factors remain unchanged, no recalculations had to be carried out.

Planned improvements

There are no improvements planned for this emission source category.
