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

===== Short description =====

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

===== Methodology =====

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.

==== Activity data ====

__Table 1: Population development in Germany since 1990, in Mio inhabitants__
|             ^  1990   ^  1995   ^  2000   ^  2005   ^  2006   ^  2007   ^  2008   ^  2009   ^  2010   ^  2011   ^  2012   ^  2013   ^  2014   ^  2015   ^  2016   ^  2017   ^  2018   ^  2019   ^  2020   ^
^ population  |  79.75  |  81.31  |  81.46  |  81.34  |  81.17  |  80.99  |  80.76  |  80.48  |  80.28  |  80.27  |  80.52  |  80.77  |  81.20  |  82.18  |  82.52  |  82.79  |  83.02  |  83.17  |  83.16  |

==== 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.

__Table 2: EF used for 2019 emissions estimates, in kg/capita__
^ Total suspended particles - TSP  |  0.3052  |
^ PM<sub>10</sub>                  |  0.1008  |
^ PM<sub>2.5</sub>                 |  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.

===== Recalculations =====

There are no recalculations compared to last year's submission.
