ÃÃÃÃÃÃÉÃÃÃÃÃÃÃÃÃ The 1985-2010 time series of NMVOC and CO emissions are shown in Figures
3.68 and 3.69 for other mobile sources. The 2010 sector emission shares
are shown in Figure 3.74. For NMVOC, the most important sectors are
Commercial/Institutional (1A4a), Agriculture/forestry/-fisheries (1A4c),
Residential (1A4b), Industry (1A2f) and Navigation (1A3d) with 2010 emission
shares of 40, 21, 18, 10 and 8 %, respectively. The same five sectors also
contribute with most of the CO emissions. For Commercial/Institutional
(1A4a), Residential (1A4b), Agriculture/forestry/fisheries (1A4c), Industry
(1A2f) and Navigation (1A3d) the emission shares are 55, 20, 15, 5 and 4 %,
respectively. Minor NMVOC and CO emissions come from Railways (1A3c),
Civil Aviation (1A3a) and Military (1A5).
For NMVOC and CO, the significant emission increases for the commercial/institutional
and residential sectors after 2000 are due to the increased
number of gasoline working machines. Improved NMVOC emission factors
for diesel machinery in agriculture and gasoline equipment in forestry
(chain saws) are the most important explanations for the NMVOC emission
decline in the Agriculture/forestry/fisheries sector. This explanation also
applies for the industrial sector, which is dominated by diesel-fuelled machinery.
From 1997 onwards, the NMVOC emissions from Navigation decrease
due to the gradually phase-out of the 2-stroke engine technology for
recreational craft. The main reason for the significant 1985-2006 CO emission
decrease for Agriculture/forestry-/fisheries is the phasing out of gasoline
tractors.
As shown in Figure 3.74, for other mobile sources the largest TSP contributors
in 2010 are Agriculture/forestry/fisheries (1A4c), Industry (1A2f) and
Navigation (1A3d), with emission shares of 46, 32 and 14 %, respectively.
The remaining sectors: Railways (1A3c), Civil aviation (1A3a), Military (1A5)
and Residential (1A4b) represent only minor emission sources.
The 1985-2009 TSP emissions for navigation and fisheries are determined by
the fuel consumption fluctuations in these years, and the development of the
emission factors, which to a major extent is a function of the fuel sulphur
content. The emission development for Agriculture/forestry is determined
by the generally decreasing total diesel fuel consumption and gradually reducing
emission factors over the time period.
The TSP emission development for industrial non-road machinery is the
product of a fuel consumption increase from 1985 to 2008 and a develop-
